General Description Altera's Flexible Logic Element MatriX (FLEX(R)) family combines the benefits of both erasable programmable logic devices (EPLDs) and fieldprogrammable gate arrays (FPGAs). The FLEX 8000 device family is ideal for a variety of applications because it combines the fine-grained architecture and high register count characteristics of FPGAs with the high speed and predictable interconnect delays of EPLDs. Logic is implemented in LEs that include compact 4-input look-up tables (LUTs) and programmable registers. High performance is provided by a fast, continuous network of routing resources. 2 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet FLEX 8000 devices provide a large number of storage elements for applications such as digital signal processing (DSP), wide-data-path manipulation, and data transformation. These devices are an excellent choice for bus interfaces, TTL integration, coprocessor functions, and high-speed controllers. The high-pin-count packages can integrate multiple 32-bit buses into a single device. Table 3 shows FLEX 8000 performance and LE requirements for typical applications. Table 3.

Each I/O pin has an associated register on the periphery of the device. As outputs, these registers provide fast clock-to-output times; as inputs, they offer quick setup times. The logic and interconnections in the FLEX 8000 architecture are configured with CMOS SRAM elements. FLEX 8000 devices are configured at system power-up with data stored in an industry-standard parallel EPROM or an Altera serial Configuration EPROM device, or with data provided by a system controller. Altera offers the EPC1, EPC1213, EPC1064, and EPC1441 Configuration EPROMs, which configure FLEX 8000 devices via a serial data stream. Configuration data can also be stored in an industry-standard 32 K x 8 bit or larger EPROM, or downloaded from system RAM. After a FLEX 8000 device has been configured, it can be reconfigured in-circuit by resetting the device and loading new data. Because reconfiguration requires less than 100 ms, realtime changes can be made during system operation. f For information on how to configure FLEX 8000 devices, go to the following documents: s s s s s Configuration EPROMs for FLEX Devices Data Sheet BitBlaster Serial Download Cable Data Sheet ByteBlaster Parallel Port Download Cable Data Sheet Application Note 33 (Configuring FLEX 8000 Devices) Application Note 38 (Configuring Multiple FLEX 8000 Devices) 3 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet FLEX 8000 devices contain an optimized microprocessor interface that permits the microprocessor to configure FLEX 8000 devices serially, in parallel, synchronously, or asynchronously. The interface also enables the microprocessor to treat a FLEX 8000 device as memory and configure the device by writing to a virtual memory location, making it very easy for the designer to create configuration software. The FLEX 8000 family is supported by Altera's MAX+PLUS II development system, a single, integrated package that offers schematic, text--including the Altera Hardware Description Language (AHDL), VHDL, and Verilog HDL--and waveform design entry; compilation and logic synthesis; simulation and timing analysis; and device programming. The MAX+PLUS II software provides EDIF 2 0 0 and 3 0 0, library of parameterized modules (LPM), VHDL, Verilog HDL, and other interfaces for additional design entry and simulation support from other industrystandard PC- and UNIX workstation-based EDA tools. The MAX+PLUS II software runs on 486- and Pentium-based PCs, and Sun SPARCstation, HP 9000 Series 700/800, and IBM RISC System/6000 workstations. The MAX+PLUS II software interfaces easily with common gate array EDA tools for synthesis and simulation. For example, the MAX+PLUS II software can generate Verilog HDL files for simulation with tools such as Cadence Verilog-XL. Additionally, the MAX+PLUS II software contains EDA libraries that use device-specific features such as carry chains, which are used for fast counter and arithmetic functions. For instance, the Synopsys Design Compiler library supplied with the MAX+PLUS II development system includes DesignWare functions that are optimized for the FLEX 8000 architecture. f Functional Description For more information on the MAX+PLUS II software, go to the MAX+PLUS II Programmable Logic Development System & Software Data Sheet in this data book. The FLEX 8000 architecture incorporates a large matrix of compact building blocks called logic elements (LEs). Each LE contains a 4-input LUT that provides combinatorial logic capability and a programmable register that offers sequential logic capability. The fine-grained structure of the LE provides highly efficient logic implementation. Eight LEs are grouped together to form a logic array block (LAB). Each FLEX 8000 LAB is an independent structure with common inputs, interconnections, and control signals. The LAB architecture provides a coarse-grained structure for high device performance and easy routing. 4 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet Figure 1 shows a block diagram of the FLEX 8000 architecture. Each group of eight LEs is combined into an LAB; LABs are arranged into rows and columns. The I/O pins are supported by I/O elements (IOEs) located at the ends of rows and columns. Each IOE contains a bidirectional I/O buffer and a flipflop that can be used as either an input or output register. Figure 1.

IOEs are located at the end of each row (horizontal) and column (vertical) FastTrack Interconnect path. Altera Corporation 5 FLEX 8000 Programmable Logic Device Family Data Sheet Logic Array Block A logic array block (LAB) consists of eight LEs, their associated carry and cascade chains, LAB control signals, and the LAB local interconnect. The LAB provides the coarse-grained structure of the FLEX 8000 architecture. This structure enables FLEX 8000 devices to provide efficient routing, high device utilization, and high performance. Figure 2 shows a block diagram of the FLEX 8000 LAB. Figure 2.

Two of these signals can be used as clocks, and the other two for clear/preset control. The LAB control signals can be driven directly from a dedicated input pin, an I/O pin, or any internal signal via the LAB local interconnect. The dedicated inputs are typically used for global clock, clear, or preset signals because they provide synchronous control with very low skew across the device. FLEX 8000 devices support up to four individual global clock, clear, or preset control signals. If logic is required on a control signal, it can be generated in one or more LEs in any LAB and driven into the local interconnect of the target LAB. This process is called programmable inversion, and is available for all four LAB control signals. Logic Element The logic element (LE) is the smallest unit of logic in the FLEX 8000 architecture, with a compact size that provides efficient logic utilization. Each LE contains a 4-input LUT, a programmable flipflop, a carry chain, and cascade chain. Figure 3 shows a block diagram of an LE. Figure 3. FLEX 8000 LE Carry-In Cascade-In DATA1 DATA2 DATA3 DATA4 DFF Look-Up Table (LUT) Carry Chain Cascade Chain D PRN Q LE-Out CLRN LABCTRL1 LABCTRL2 Clear/ Preset Logic Clock Select LABCTRL3 LABCTRL4 Carry-Out Cascade-Out The LUT is a function generator that can quickly compute any function of four variables. The programmable flipflop in the LE can be configured for D, T, JK, or SR operation. The clock, clear, and preset control signals on the flipflop can be driven by dedicated input pins, general-purpose I/O pins, or any internal logic. For purely combinatorial functions, the flipflop is bypassed and the output of the LUT goes directly to the output of the LE. Altera Corporation 7 FLEX 8000 Programmable Logic Device Family Data Sheet The FLEX 8000 architecture provides two dedicated high-speed data paths--carry chains and cascade chains--that connect adjacent LEs without using local interconnect paths. The carry chain supports highspeed counters and adders; the cascade chain implements wide-input functions with minimum delay. Carry and cascade chains connect all LEs in an LAB and all LABs in the same row. Heavy use of carry and cascade chains can reduce routing flexibility. Therefore, the use of carry and cascade chains should be limited to speed-critical portions of a design. Carry Chain The carry chain provides a very fast (less than 1 ns) carry-forward function between LEs. The carry-in signal from a lower-order bit moves forward into the higher-order bit via the carry chain, and feeds into both the LUT and the next portion of the carry chain. This feature allows the FLEX 8000 architecture to implement high-speed counters and adders of arbitrary width. The MAX+PLUS II Compiler can create carry chains automatically during design processing; designers can also insert carry chain logic manually during design entry. Figure 4 shows how an n-bit full adder can be implemented in n + 1 LEs with the carry chain. One portion of the LUT generates the sum of two bits using the input signals and the carry-in signal; the sum is routed to the output of the LE. The register is typically bypassed for simple adders, but can be used for an accumulator function. Another portion of the LUT and the carry chain logic generate the carry-out signal, which is routed directly to the carry-in signal of the next-higher-order bit. The final carry-out signal is routed to another LE, where it can be used as a general-purpose signal. In addition to mathematical functions, carry chain logic supports very fast counters and comparators. 8 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet Figure 4. FLEX 8000 Carry Chain Operation Carry-In a1 b1 LU Register s1 Carry LE a2 b2 LUT Register s2 Carry Chain LE an bn LUT Register sn Carry Chain LE LUT Register Carry-Out Carry Chain LEn + 1 Cascade Chain With the cascade chain, the FLEX 8000 architecture can implement functions that have a very wide fan-in. Adjacent LUTs can be used to compute portions of the function in parallel; the cascade chain serially connects the intermediate values. The cascade chain can use a logical AND or logical OR (via De Morgan's inversion) to connect the outputs of adjacent LEs. Each additional LE provides four more inputs to the effective width of a function, with a delay as low as 0.6 ns per LE. Altera Corporation 9 FLEX 8000 Programmable Logic Device Family Data Sheet The MAX+PLUS II Compiler can create cascade chains automatically during design processing; designers can also insert cascade chain logic manually during design entry. Cascade chains longer than eight LEs are automatically implemented by linking LABs together. The last LE of an LAB cascades to the first LE in the next LAB in the row. Figure 5 shows how the cascade function can connect adjacent LEs to form functions with a wide fan-in. These examples show functions of 4n variables implemented with n LEs. For a device with an A-2 speed grade, the LUT delay is approximately 1.6 ns; the cascade chain delay is 0.6 ns. With the cascade chain, 4.2 ns is needed to decode a 16-bit address. Figure 5.

See Figure 6. In each mode, seven of the ten available inputs to the LE--the four data inputs from the LAB local interconnect, the feedback from the programmable register, and the carry-in and cascade-in from the previous LE--are directed to different destinations to implement the desired logic function. The three remaining inputs to the LE provide clock, clear, and preset control for the register. The MAX+PLUS II software automatically chooses the appropriate mode for each application. Design performance can also be enhanced by designing for the operating mode that supports the desired application. 10 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet Figure 6.

In normal mode, four data inputs from the LAB local interconnect and the carry-in signal are the inputs to a 4-input LUT. Using a configurable SRAM bit, the MAX+PLUS II Compiler automatically selects the carry-in or the DATA3 signal as an input. The LUT output can be combined with the cascade-in signal to form a cascade chain through the cascade-out signal. The LE-Out signal--the data output of the LE--is either the combinatorial output of the LUT and cascade chain, or the data output (Q)of the programmable register. Arithmetic Mode The arithmetic mode offers two 3-input LUTs that are ideal for implementing adders, accumulators, and comparators. One LUT provides a 3-bit function; the other generates a carry bit. As shown in Figure 6, the first LUT uses the carry-in signal and two data inputs from the LAB local interconnect to generate a combinatorial or registered output. For example, in an adder, this output is the sum of three bits: a, b, and the carry-in. The second LUT uses the same three signals to generate a carry-out signal, thereby creating a carry chain. The arithmetic mode also supports a cascade chain. Up/Down Counter Mode The up/down counter mode offers counter enable, synchronous up/down control, and data loading options. These control signals are generated by the data inputs from the LAB local interconnect, the carry-in signal, and output feedback from the programmable register. Two 3-input LUTs are used: one generates the counter data, and the other generates the fast carry bit. A 2-to-1 multiplexer provides synchronous loading. Data can also be loaded asynchronously with the clear and preset register control signals, without using the LUT resources. Clearable Counter Mode The clearable counter mode is similar to the up/down counter mode, but supports a synchronous clear instead of the up/down control; the clear function is substituted for the cascade-in signal in the up/down counter mode. Two 3-input LUTs are used: one generates the counter data, and the other generates the fast carry bit. Synchronous loading is provided by a 2-to-1 multiplexer, and the output of this multiplexer is ANDed with a synchronous clear. 12 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet Internal Tri-State Emulation Internal tri-state emulation provides internal tri-stating without the limitations of a physical tri-state bus. In a physical tri-state bus, the tri-state buffers' output enable signals select the signal that drives the bus. However, if multiple output enable signals are active, contending signals can be driven onto the bus. Conversely, if no output enable signals are active, the bus will float. Internal tri-state emulation resolves contending tri-state buffers to a low value and floating buses to a high value, thereby eliminating these problems. The MAX+PLUS II software automatically implements tri-state bus functionality with a multiplexer. Clear & Preset Logic Control Logic for the programmable register's clear and preset functions is controlled by the DATA3, LABCTRL1, and LABCTRL2 inputs to the LE. The clear and preset control structure of the LE is used to asynchronously load signals into a register. The register can be set up so that LABCTRL1 implements an asynchronous load. The data to be loaded is driven to DATA3; when LABCTRL1 is asserted, DATA3 is loaded into the register. During compilation, the MAX+PLUS II Compiler automatically selects the best control signal implementation. Because the clear and preset functions are active-low, the Compiler automatically assigns a logic high to an unused clear or preset. The clear and preset logic is implemented in one of the following six asynchronous modes, which are chosen during design entry. LPM functions that use registers will automatically use the correct asynchronous mode. See Figure 7. s s s s s s Clear only Preset only Clear and preset Load with clear Load with preset Load without clear or preset Altera Corporation 13 FLEX 8000 Programmable Logic Device Family Data Sheet Figure 7.

When the CLRn port receives a low signal, the register is set to zero. Asynchronous Preset An asynchronous preset is implemented as either an asynchronous load or an asynchronous clear. If DATA3 is tied to VCC, asserting LABCTRLl asynchronously loads a 1 into the register. Alternatively, the MAX+PLUS II software can provide preset control by using the clear and inverting the input and output of the register. Inversion control is available for the inputs to both LEs and IOEs. Therefore, if a register is preset by only one of the two LABCTRL signals, the DATA3 input is not needed and can be used for one of the LE operating modes. Asynchronous Clear & Preset When implementing asynchronous clear and preset, LABCTRL1 controls the preset and LABCTRL2 controls the clear. The DATA3 input is tied to VCC; therefore, asserting LABCTRL1 asynchronously loads a 1 into the register, effectively presetting the register. Asserting LABCTRL2 clears the register. Asynchronous Load with Clear When implementing an asynchronous load with the clear, LABCTRL1 implements the asynchronous load of DATA3 by controlling the register preset and clear. LABCTRL2 implements the clear by controlling the register clear. Asynchronous Load with Preset When implementing an asynchronous load in conjunction with a preset, the MAX+PLUS II software provides preset control by using the clear and inverting the input and output of the register. Asserting LABCTRL2 clears the register, while asserting LABCTRL1 loads the register. The MAX+PLUS II software inverts the signal that drives the DATA3 signal to account for the inversion of the register's output. Asynchronous Load without Clear or Preset When implementing an asynchronous load without the clear or preset, LABCTRL1 implements the asynchronous load of DATA3 by controlling the register preset and clear. Altera Corporation 15 FLEX 8000 Programmable Logic Device Family Data Sheet FastTrack Interconnect In the FLEX 8000 architecture, connections between LEs and device I/O pins are provided by the FastTrack Interconnect, a series of continuous horizontal (row) and vertical (column) routing channels that traverse the entire FLEX 8000 device. This device-wide routing structure provides predictable performance even in complex designs. In contrast, the segmented routing structure in FPGAs requires switch matrices to connect a variable number of routing paths, which increases the delays between logic resources and reduces performance. The LABs within FLEX 8000 devices are arranged into a matrix of columns and rows. Each row of LABs has a dedicated row interconnect that routes signals both into and out of the LABs in the row. The row interconnect can then drive I/O pins or feed other LABs in the device. Figure 8 shows how an LE drives the row and column interconnect. Figure 8. FLEX 8000 LAB Connections to Row & Column Interconnect 16 Column Channels Row Channels Note (1) Each LE drives one row channel. LE1 LE2 to Local to Local Feedback Feedback Note: (1) See Table 4 for the number of row channels. Each LE drives up to two column channels. 16 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet Each LE in an LAB can drive up to two separate column interconnect channels. Therefore, all 16 available column channels can be driven by the LAB. The column channels run vertically across the entire device, and share access to LABs in the same column but in different rows. The MAX+PLUS II Compiler chooses which LEs must be connected to a column channel. A row interconnect channel can be fed by the output of the LE or by two column channels. These three signals feed a multiplexer that connects to a specific row channel. Each LE is connected to one 3-to-1 multiplexer. In an LAB, the multiplexers provide all 16 column channels with access to 8 row channels. Each column of LABs has a dedicated column interconnect that routes signals out of the LABs into the column. The column interconnect can then drive I/O pins or feed into the row interconnect to route the signals to other LABs in the device. A signal from the column interconnect, which can be either the output of an LE or an input from an I/O pin, must transfer to the row interconnect before it can enter an LAB. Table 4 summarizes the FastTrack Interconnect resources available in each FLEX 8000 device. Table 4.

IOEs can be used as input, output, or bidirectional pins. The MAX+PLUS II Compiler uses the programmable inversion option to automatically invert signals from the row and column interconnect where appropriate. Figure 10 shows the IOE block diagram. 18 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet Figure 10. FLEX 8000 IOE Numbers in parentheses are for EPF81500A devices only.

An input signal from an IOE can drive two separate row channels. When an IOE is used as an output, the signal is driven by an n-to-1 multiplexer that selects the row channels. The size of the multiplexer varies with the number of columns in a device. EPF81500A devices use a 27-to-1 multiplexer; EPF81188A, EPF8820A, EPF8636A, and EPF8452A devices use a 21-to-1 multiplexer; and EPF8282A and EPF8282AV devices use a 13-to-1 multiplexer. Eight IOEs are connected to each side of the row channels. Altera Corporation (OE [4..9]) 19 FLEX 8000 Programmable Logic Device Family Data Sheet Figure 11.

Column-to-IOE Connections Two IOEs are located at the top and bottom of the column channels (see Figure 12). When an IOE is used as an input, it can drive up to two separate column channels. The output signal to an IOE can choose from 8 of the 16 column channels through an 8-to-1 multiplexer. 20 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet Figure 12.

IOE IOE Each IOE can drive up to two column signals. 8 8 16 Column Interconnect In addition to general-purpose I/O pins, FLEX 8000 devices have four dedicated input pins. These dedicated inputs provide low-skew, devicewide signal distribution, and are typically used for global clock, clear, and preset control signals. The signals from the dedicated inputs are available as control signals for all LABs and I/O elements in the device. The dedicated inputs can also be used as general-purpose data inputs because they can feed the local interconnect of each LAB in the device. Signals enter the FLEX 8000 device either from the I/O pins that provide general-purpose input capability or from the four dedicated inputs. The IOEs are located at the ends of the row and column interconnect channels. I/O pins can be used as input, output, or bidirectional pins. Each I/O pin has a register that can be used either as an input register for external data that requires fast setup times, or as an output register for data that requires fast clock-to-output performance. The MAX+PLUS II Compiler uses the programmable inversion option to automatically invert signals from the row and column interconnect when appropriate. The clock, clear, and output enable controls for the IOEs are provided by a network of I/O control signals. These signals can be supplied by either the dedicated input pins or by internal logic. The IOE control-signal paths are designed to minimize the skew across the device. All control-signal sources are buffered onto high-speed drivers that drive the signals around the periphery of the device. This "peripheral bus" can be configured to provide up to four output enable signals (10 in EPF81500A devices), and up to two clock or clear signals. Figure 13 shows how two output enable signals are shared with one clock and one clear signal. Altera Corporation 21 FLEX 8000 Programmable Logic Device Family Data Sheet The signals for the peripheral bus can be generated by any of the four dedicated inputs or signals on the row interconnect channels, as shown in Figure 13. The number of row channels in a row that can drive the peripheral bus correlates to the number of columns in the FLEX 8000 device. EPF8282A and EPF8282AV devices use 13 channels; EPF8452A, EPF8636A, EPF8820A, and EPF81188A devices use 21 channels; and EPF81500A devices use 27 channels. The first LE in each LAB is the source of the row channel signal. The six peripheral control signals (12 in EPF81500A devices) can be accessed by each IOE. Figure 13.

Slew-Rate Control The output buffer in each IOE has an adjustable output slew rate that can be configured for low-noise or high-speed performance. A slow slew rate reduces system noise by slowing signal transitions, adding a maximum delay of 3.5 ns. The slow slew-rate setting affects only the falling edge of a signal. The fast slew rate should be used for speed-critical outputs in systems that are adequately protected against noise. Designers can specify the slew rate on a pin-by-pin basis during design entry or assign a default slew rate to all pins on a global basis. f For more information on high-speed system design, go to Application Note 75 (High-Speed Board Designs) in this data book. Altera Corporation 23 FLEX 8000 Programmable Logic Device Family Data Sheet MultiVolt I/O Interface The FLEX 8000 device architecture supports the MultiVolt I/O interface feature, which allows EPF81500A, EPF81188A, EPF8820A, and EPF8636A devices to interface with systems with differing supply voltages. These devices in all packages--except for EPF8636A devices in 84-pin PLCC packages--can be set for 3.3-V or 5.0-V I/O pin operation. These devices have one set of VCC pins for internal operation and input buffers (VCCINT), and another set for I/O output drivers (VCCIO). The VCCINT pins must always be connected to a 5.0-V power supply. With a 5.0-V VCCINT level, input voltages are at TTL levels and are therefore compatible with 3.3-V and 5.0-V inputs. The VCCIO pins can be connected to either a 3.3-V or 5.0-V power supply, depending on the output requirements. When the VCCIO pins are connected to a 5.0-V power supply, the output levels are compatible with 5.0-V systems. When the VCCIO pins are connected to a 3.3-V power supply, the output high is at 3.3 V and is therefore compatible with 3.3-V or 5.0-V systems. Devices operating with VCCIO levels lower than 4.75 V incur a nominally greater timing delay of tOD2 instead of tOD1. See Table 7 on page 26. IEEE 1149.1 (JTAG) Boundary-Scan Support The EPF8282A, EPF8282AV, EPF8636A, EPF8820A, and EPF81500A devices provide JTAG BST circuitry. FLEX 8000 devices with JTAG circuitry support the JTAG instructions shown in Table 6. Figure 14 shows the timing requirements for the JTAG signals. Table 6. EPF8282A, EPF8282AV, EPF8636A, EPF8820A & EPF81500A JTAG Instructions JTAG Instruction Description SAMPLE/PRELOAD Allows a snapshot of the signals at the device pins to be captured and examined during normal device operation, and permits an initial data pattern to be output at the device pins. EXTEST BYPASS Allows the external circuitry and board-level interconnections to be tested by forcing a test pattern at the output pins and capturing test results at the input pins. Places the 1-bit bypass register between the TDI and TDO pins, which allows the BST data to pass synchronously through the selected device to adjacent devices during normal device operation. 24 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet Figure 14.

Each FLEX 8000 device is functionally tested and specified by Altera. Complete testing of each configurable SRAM bit and all logic functionality ensures 100% configuration yield. AC test measurements for FLEX 8000 devices are made under conditions equivalent to those shown in Figure 15. Designers can use multiple test patterns to configure devices during all stages of the production flow. 26 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet Figure 15. FLEX 8000 AC Test Conditions Power supply transients can affect AC measurements. Simultaneous transitions of multiple outputs should be avoided for accurate measurement. Threshold tests must not be performed under AC conditions. Large-amplitude, fast-ground-current transients normally occur as the device outputs discharge the load capacitances. When these transients flow through the parasitic inductance between the device ground pin and the test system ground, significant reductions in observable noise immunity can result.

This predictable performance contrasts with that of FPGAs, which use a segmented connection scheme and hence have unpredictable performance. Timing simulation and delay prediction are available with the MAX+PLUS II Simulator and Timing Analyzer, or with industry-standard EDA tools. The Simulator offers both pre-synthesis functional simulation to evaluate logic design accuracy and postsynthesis timing simulation with 0.1-ns resolution. The Timing Analyzer provides point-to-point timing delay information, setup and hold time prediction, and device-wide performance analysis.

They are worst-case delays based on testable and external parameters specified by Altera. Internal timing parameters should be used for estimating device performance. Post-compilation timing simulation or timing analysis is required to determine actual worst-case performance. These values are specified under "FLEX 8000 3.3-V Device Recommended Operating Conditions" on page 29. For the tOD3 and tZX3 parameters, VCCIO = 3.3 V or 5.0 V. The t ROW and t DIN_D delays are worst-case values for typical applications. Post-compilation timing simulation or timing analysis is required to determine actual worst-case performance. External reference timing characteristics are factory-tested, worst-case values specified by Altera. A representative subset of signal paths is tested to approximate typical device applications. For more information on test conditions, see Application Note 76 (Understanding FLEX 8000 Timing) in this data book.

This model contains three distinct parts: the LE; the IOE; and the interconnect, including the row and column FastTrack Interconnect, LAB local interconnect, and carry and cascade interconnect paths. Each parameter shown in Figure 19 is expressed as a worst-case value in the "Timing Parameters" tables in this data sheet. Hand-calculations that use the FLEX 8000 timing model and these timing parameters can be used to estimate FLEX 8000 device performance.

the following equation: P = PINT + PIO = [(I CCSTANDBY + I CCACTIVE) x VCC] + PIO Typical I CCSTANDBY values are shown as I CC0 in the "FLEX 8000 5.0-V Device DC Operating Conditions" table on page 28 and the "FLEX 8000 3.3-V Device DC Operating Conditions" table on page 29. The PIO value, which depends on the device output load characteristics and switching frequency, can be calculated using the guidelines given in Application Note 74 (Evaluating Power for Altera Devices). The I CCACTIVE value depends on the switching frequency and the application logic. This value can be calculated based on the amount of current that each LE typically consumes. The following equation shows the general formula for calculating ICCACTIVE: A ICCACTIVE = K x f MAX x N x tog LC x --------------------------MHz x LE The parameters in this equation are shown below: fMAX N togLC K = = = = Maximum operating frequency in MHz Total number of logic cells used in the device Average percentage of logic cells toggling at each clock Constant, shown in Table 13 Table 13. Values for Constant K Device 5.0-V FLEX 8000 devices 3.3-V FLEX 8000 devices K 75 60 This calculation provides an I CC estimate based on typical conditions with no output load. The actual I CC value should be verified during operation because this measurement is sensitive to the actual pattern in the device and the environmental operating conditions. Figure 20 shows the relationship between I CC and operating frequency for several LE utilization values. 50 Altera Corporation FLEX 8000 Programmable Logic Device Family Data Sheet Figure 20.

This section summarizes the device operating modes and available device configuration schemes. For more information, go to Application Note 33 (Configuring FLEX 8000 Devices) and Application Note 38 (Configuring Multiple FLEX 8000 Devices). 51 FLEX 8000 Programmable Logic Device Family Data Sheet Operating Modes The FLEX 8000 architecture uses SRAM elements that require configuration data to be loaded whenever the device powers up and begins operation. The process of physically loading the SRAM programming data into the device is called configuration. During initialization, which occurs immediately after configuration, the device resets registers, enables I/O pins, and begins to operate as a logic device. The I/O pins are tri-stated during power-up, and before and during configuration. The configuration and initialization processes together are called command mode; normal device operation is called user mode. SRAM elements allow FLEX 8000 devices to be reconfigured in-circuit with new programming data that is loaded into the device. Real-time reconfiguration is performed by forcing the device into command mode with a device pin, loading different programming data, reinitializing the device, and resuming user-mode operation. The entire reconfiguration process requires less than 100 ms and can be used to dynamically reconfigure an entire system. In-field upgrades can be performed by distributing new configuration files. Configuration Schemes The configuration data for a FLEX 8000 device can be loaded with one of six configuration schemes, chosen on the basis of the target application. Both active and passive schemes are available. In the active configuration schemes, the FLEX 8000 device functions as the controller, directing the loading operation, controlling external EPROM devices, and completing the loading process. The clock source for all active configuration schemes is an oscillator on the FLEX 8000 device that operates between 2 MHz and 6 MHz. In the passive configuration schemes, an external controller guides the FLEX 8000 device. Table 14 shows the data source for each of the six configuration schemes. Table 14.

(3) SDOUT will drive out during configuration. After configuration, it may be used as a user I/O pin. By default, the MAX+PLUS II software will not use SDOUT as a user I/O pin; the user can override the MAX+PLUS II software and use SDOUT as a user I/O pin. (4) If the device is not configured to use the JTAG BST circuitry, this pin is available as a user I/O pin. (5) JTAG pins are available for EPF8636A devices only. These pins are dedicated user I/O pins. (6) TRST is a dedicated input pin for JTAG use. This pin must be grounded if JTAG BST is not used. (7) Pin 52 is a VCC pin on EPF8452A devices only. (8) Unused dedicated inputs should be tied to ground on the board. (9) SDOUT does not exist in the EPF8636GC192 device. (10) These pins are no connect (N.C.) pins for EPF8636A devices only. They are user I/O pins in EPF8820A devices. (11) EPF8636A devices have 132 user I/O pins; EPF8820A devices have 148 user I/O pins. (12) For EPF81500A devices, these pins are dedicated JTAG pins and are not available as user I/O pins. If JTAG BST is not used, TRST must be grounded. TMS, TDI, and TCK should be tied to VCC.
