Functional Description
Warp ProfessionalTM is an integration of the Warp(R) CPLD Development package with additional sophisticated EDA software features from Aldec. In addition to accepting IEEE 1076/1164 VHDL text, IEEE 1364 Verilog text and graphical finite state machines for design entry, Warp Professional provides a graphical HDL block diagram editor with a library of graphical HDL blocks pre-optimized for Cypress devices. It synthesizes and optimizes the entered design, and outputs a JEDEC or Intel hex file for the desired PLD or CPLD (see Figure 1). For simulation, Warp Professional provides a timing simulator, as well as VHDL timing models for use with third party simulators. Warp Professional also provides the designer with important productivity tools like the Architecture Explorer graphical analysis tool. * San Jose * CA 95134 * 408-943-2600 Revised January 9, 2002

DESIGN ENTRY
COMPILATION
The VHDL and Verilog languages also allow users to define their own functions. User-defined functions allow users to extend the capabilities of the language and build reusable files of tested routines. VHDL and Verilog provide control over the timing of events or processes. They have constructs that identify processes as either sequential, concurrent, or a combination of both. This is essential when describing the interaction of complex state machines. VHDL and Verilog are rich programming languages. Their flexibility reflects the nature of modern digital systems and allows designers to create accurate models of digital designs. Because they are not verbose languages they are easy to learn and compile. In addition, models created in VHDL and Verilog can readily be transported to other EDA Environments. Warp Professional supports IEEE 1076/1164 VHDL including loops, for/generate statements, full hierarchical designs with packages, enumerated types, and integers as well as IEEE 1364 Verilog including loops, reduction and conditional operators.

A VHDL Design Example
Design Entry Warp Professional descriptions specify: * The behavior or structure of a design, and * The mapping of signals in a design to the pins of a PLD/CPLD (optional) The part of a Warp Professional description that specifies the behavior or structure of the design is called an entity/architecture pair. Entity/architecture pairs, as their name implies, are divided into two parts: an entity declaration, which declares the design's interface signals (i.e., defines what external signals the design has, and what their directions and types are), and a design architecture, which describes the design's behavior or structure. The entity portion of a design file is a declaration of what a design presents to the outside world (the interface). For each external signal, the entity declaration specifies a signal name, a direction and a data type. In addition, the entity declaration specifies a name by which the entity can be referenced in a design architecture. This section shows code segments from five sample design files. The top portion of each example features the entity declaration. Behavioral Description The architecture portion of a design file specifies the function of the design. As shown in Figure 1, multiple design-entry methods are supported in Warp Professional. A behavioral description in VHDL often includes well known constructs such as If...Then...Else, and Case statements. Here is a code segment from a simple state machine design (soda vending machine) that uses behavioral VHDL to implement the design: LIBRARY ieee; USE ieee.std_logic_1164.all; ENTITY drink IS PORT (nickel,dime,quarter,clock:#in Page 2 of 8
Figure 1. Warp(R) Design Flow VHDL and Verilog Compilers VHDL and Verilog are powerful, industry standard languages for behavioral design entry and simulation, and are supported by all major vendors of EDA tools. They allow designers to learn a single language that is useful for all facets of the design process. VHDL and Verilog offer designers the ability to describe designs at many different levels. At the highest level, designs can be entered as a description of their behavior. This behavioral description is not tied to any specific target device. As a result, simulation can be done very early in the design to verify correct functionality, which significantly speeds the design process. The Warp syntax for VHDL and Verilog includes support for intermediate level entry modes such as state tables and Boolean entry. At the lowest level, designs can be described using gate-level descriptions. Warp Professional gives the designer the flexibility to intermix all of these entry modes. In addition, Verilog and VHDL allow you to design hierarchically, building up entities in terms of other entities. This allows you to work either "top-down" (designing the highest levels of the system and its interfaces first, then progressing to greater and greater detail) or "bottom-up" (designing elementary building blocks of the system, then combining these to build larger and larger parts) with equal ease. Because these languages are IEEE standards, multiple vendors offer tools for design entry and simulation at both high and low levels and synthesis of designs to different silicon targets. The use of device-independent behavioral design entry gives users the freedom to easily migrate to high volume technologies. The wide availability of VHDL and Verilog tools provides complete vendor independence as well. Designers can begin

LIBRARY ieee; USE ieee.std_logic_1164.all; USE work.std_arith.all; ENTITY sequence IS port (clk: in std_logic; s : inout std_logic); end sequence; ARCHITECTURE fsm OF sequence IS SIGNAL count: std_logic_vector(3 downto 0); BEGIN PROCESS BEGIN WAIT UNTIL clk = '1'; CASE count IS WHEN x"0" | x"1" | x"2" | x"3" => s <= '1'; count <= count + 1; WHEN x"4" | x"5" | x"6" | x"7" => s <= '0'; count <= count + 1; WHEN x"8" | x"9" => s <= '1'; count <= count + 1; WHEN others => s <= '0'; count <= (others => '0'); END CASE; END PROCESS; END FSM; In this example, the + operator is overloaded to accept both integer and std_logic arguments. Warp Professional supports overloading of operators. Functions A major advantage of VHDL is the ability to implement functions. The support of functions allows designs to be reused by simply specifying a function and passing the appropriate parameters. Warp Professional features some built-in functions such as ttf (truth-table function). The ttf function is particularly useful for state machine or look-up table designs. The following code describes a seven-segment display decoder implemented with the ttf function: LIBRARY ieee; USE ieee.std_logic_1164.all; USE work.table_std.all; ENTITY seg7 IS PORT( inputs: IN STD_LOGIC_VECTOR (0 to 3) outputs: OUT STD_LOGIC_VECTOR (0 to 6) ); END SEG7; ARCHITECTURE mixed OF seg7 IS Page 3 of 8
ARCHITECTURE fsm OF drink IS TYPE drinkState IS (zero,five,ten,fifteen, twenty,twentyfive,owedime); SIGNAL drinkstatus:drinkState; BEGIN PROCESS BEGIN WAIT UNTIL clock = '1'; giveDrink <= '0'; returnDime <= '0'; returnNickel <= '0'; CASE drinkStatus IS WHEN zero => IF (nickel = '1') THEN drinkStatus <= five; ELSIF (dime = '1') THEN drinkStatus <= Ten; ELSIF (quarter = '1') THEN drinkStatus <= twentyfive; END IF; WHEN five => IF (nickel = '1') THEN drinkStatus <= ten; ELSIF (dime = '1') THEN drinkStatus <= fifteen; ELSIF (quarter = '1') THEN giveDrink <= '1'; drinkStatus <= zero END IF; -- Several states are omitted in this -- example. The omitted states are ten, -- fifteen, twenty, and twentyfive. WHEN owedime => returnDime <= '1'; drinkStatus <= zero; when others => -- This makes sure that the state -- machine resets itself if -- it somehow gets into an undefined state. drinkStatus <= zero; END CASE; END PROCESS; END FSM; VHDL is a strongly typed language. It comes with several predefined operators, such as + and /= (add, not-equal-to). VHDL offers the capability of defining multiple meanings for operators (such as +), which results in simplification of the code written. For example, the following code segment shows Document #: 38-03047 Rev. *A
CY3128
CONSTANT truthTable: ttf_table (0 to 11, 0 to 10) := ( -- input& output -- ----------------------"0000"& "0111111", "0001"& "0000110", "0010"& "1011011", "0011"& "1001111", "0100"& "1100110", "0101"& "1101101", "0110"& "1111101", "0111"& "0000111", "1000"& "1111111", "1001"& "1101111", "101-"& "1111100", --creates E pattern "111-"& "1111100" ); BEGIN outputs <= ttf(truthTable,inputs); END mixed; Boolean Equations A third design-entry method available to Warp Professional users is Boolean equations. Figure 2 displays a schematic of a simple one-bit half adder. The following code describes how this one-bit half adder can be implemented in Warp Professional with Boolean equations: the following code shows how this design can be described in Warp Professional using structural VHDL: LIBRARY ieee; USE ieee.std_logic_1164.all; USE work.rtlpkg.all; ENTITY shifter3 IS port ( clk : IN STD_LOGIC; x : IN STD_LOGIC; q0 : OUT STD_LOGIC; q1 : OUT STD_LOGIC; q2 : OUT STD_LOGIC); END shifter3; ARCHITECTURE struct OF shifter3 IS SIGNAL q0_temp, q1_temp, q2_temp : STD_LOGIC; BEGIN d1 : DFF PORT MAP(x,clk,q0_temp); d2 : DFF PORT MAP(q0_temp,clk,q1_temp); d3 : DFF PORT MAP(q1_temp,clk,q2_temp); q0 <= q0_temp; q1 <= q1_temp; q2 <= q2_temp; END struct;

Figure 3. Three-Bit Shift Register Circuit Design All of the design-entry methods described can be mixed as desired. VHDL has the ability to combine both high- and low-level entry methods in a single file. The flexibility and power of VHDL allows users of Warp Professional to describe designs using whatever method is appropriate for their particular design.

In structural descriptions, the designer simply lists the components that make up the design and specifies how the components are wired together. Figure 3 displays the schematic of a simple 3-bit shift register and Document #: 38-03047 Rev. *A
A Verilog Design Example
Design Entry Warp Professional descriptions specify: * The behavior or structure of a design, and * the mapping of signals in a design to the pins of a PLD/CPLD (optional) The part of a Warp Professional description that specifies the behavior or structure of the design is called a module. The module declares the design's interface signals (i.e., defines what external signals the design has, and what their directions and types are). The module portion of a design file is a declaration of what a design presents to the outside world (the interface). For each external signal, the module specifies a signal name, a direction and a data type. In addition, the module declaration specifies a name by which the entity can be referenced in other modules. This section shows code segments from four sample

design files. The top portion of each example features the module declaration. Behavioral Description The module portion of a design file specifies the function of the design. As shown in Figure 1, multiple design-entry methods are supported in Warp Professional. A behavioral description in Verilog often includes well known constructs such as If...Else, and Case statements. Here is a code segment from a simple state machine design (soda vending machine) that uses behavioral Verilog to implement the design: MODULE drink (nickel, dime, quarter, clock, returnDime, returnNickel, giveDrink); INPUT nickel, dime, quarter, clock; OUTPUT returnDime,returnNickel,giveDrink; REG returnDime, returnNickel, giveDrink; PARAMETER zero = 0, five = 1, ten = 2, fifteen = 3, twenty = 4, twentyfive = 5 owedime = 6; REG[1:0] drinkStatus; ALWAYS@ (POSEDGE clock) BEGIN giveDrink = 0; returnDime = 0; returnNickel = 0; CASE(drinkStatus) zero: BEGIN IF (nickel) drinkStatus = five; ELSE IF (dime) drinkStatus = ten; ELSE IF (quarter) drinkStatus = twentyfive; END five: BEGIN IF (nickel) drinkStatus = ten; ELSE IF (dime) drinkStatus = fifteen; ELSE IF (quarter) BEGIN drinkStatus = zero; giveDrink = 1; END END // Several states are omitted in this // example. The omitted states are ten // fifteen, twenty, and twentyfive. owedime: BEGIN returnDime = 1; drinkStatus = zero; END Sum default: BEGIN // This makes sure that the state // machine resets itself if // it somehow gets into an undefined state. drinkStatus = zero; END ENDCASE END ENDMODULE Verilog is not a strongly typed language. The simplicity and readability of the following code is increased by use of the CASEX. The CASEX command accepts "Don't Cares" and chooses the branch depending on the value of the expression. MODULE sequence (clk, s); INPUT clk; INOUT s; WIRE s; REG temp; REG[3:0] count; ALWAYS@(POSEDGE clk) CASEX(count) 4'b00XX: BEGIN temp=1; count=count+1; end 4'b01XX: BEGIN temp=0; count=count+1; end 4'b100X: BEGIN temp=1; count=count+1; end default: BEGIN temp=0; count=0; end ENDCASE ASSIGN s=temp; ENDMODULE Boolean Equations A second design-entry method available to Warp Professional users is Boolean equations. Figure 4 displays a schematic of a simple one-bit half adder. The following code describes how this one-bit half adder can be implemented in Warp Professional with Boolean equations:

ASSIGN sum = x^y; ASSIGN carry = x&y; ENDMODULE Structural Verilog While all of the design methodologies described thus far are high-level entry methods, structural Verilog provides a method for designing at a very low level. In structural descriptions, the designer simply lists the components that make up the design and specifies how the components are wired together. Figure 5 displays the schematic of a simple 3-bit shift register and the following code shows how this design can be described in Warp Professional using structural Verilog. MODULE shifter3 (clk, x, q0, q1, q2); INPUT clk, x; OUTPUT q0, q1, q2; WIRE q0, q1, q2; REG q0_temp, q1_temp, q2_temp; DFF d1(x,clk,q0_temp); DFF d2(q0_temp,clk,q1_temp); DFF d3(q1_temp,clk,q2_temp); ASSIGN q0 = q0_temp; ASSIGN q1 = q1_temp; ASSIGN q2 = q2_temp; ENDMODULE; (CY3130 and CY3138) comes with a utility that converts HDL text into these blocks.
Language Assistant
The language assistant is a library of language templates that you can browse and automatically insert into your HDL text. They provide syntax and structure and give examples to aid users who are new to using a particular HDL.
Flow Manager
The flow manager is a special interface that helps you keep track of your complex projects. It arranges the tools as part of the logical flow the designer takes through a project and remembers what steps have been completed on which designs.
Compilation
Once the VHDL or Verilog description of the design is complete, it is compiled using Warp Professional. Although implementation is with a single command, compilation is actually a multistep process as shown in Figure 1. The first part of the compilation process is the same for all devices. The input description is synthesized to a logical representation of the design. Warp synthesis is unique in that the input languages support device-independent design descriptions. Competing programmable logic compilers require very specific and device-dependent information in the design description.

Warp synthesis is based on UltraGen technology. This technology allows Warp Professional to infer adders, subtractors, multipliers, comparators, counters and shifters from the behavioral descriptions. Warp Professional then replaces these operators internally with an architecture-specific circuit. This circuit or "module" is also pre-optimized for either area or speed. Warp Professional uses the appropriate implementation based on user directives. The second step of compilation is an iterative process of optimizing the design and fitting the logic into the targeted device. Logical optimization in Warp Professional is accomplished using Espresso algorithms. The optimized design is automatically fed to the Warp Professional fitter for targeting a PLD or CPLD. This fitter supports the automatic or manual placement of pin assignments as well as automatic selection of D or T flip-flops. After optimization and fitting, Warp Professional creates a JEDEC or Intel hex file for the specified PLD or CPLD.
Figure 5. Three-Bit Shift Register Circuit Design All of the design-entry methods described can be mixed as desired so long as only one HDL is used. VHDL and Verilog have the ability to combine both high- and low-level entry methods in a single file. The flexibility and power of VHDL and Verilog allow users of Warp Professional to describe designs using whatever method is appropriate for their particular design.
Automatic Error Tracking
Warp Professional features automatic error location that allows problems to be diagnosed and corrected in seconds. Errors from compilation are displayed immediately in a window. If the user highlights a particular error, Warp Professional will automatically open the source code file and highlight the offending line in the entered design. If the device fitting process includes errors, a window will again describe them. A detailed report file is generated indicating the resources required to fit the input design and any problems that occurred in the process.
Finite State Machine Editor
Aldec's Active-HDL FSM finite state machine editor, allows graphic design entry through the use of graphical state diagrams. A design may be represented graphically using state diagrams and data flow logic. This tool will automatically generate the HDL code of the design.
HDL Block Diagram Editor
The HDL block diagram editor lets you represent portions of your code with graphical symbols. This representation allows you to view the high-level structure of your complex designs and lets you copy and paste entire modules of your design within or between designs. The editor comes with a library of HDL blocks optimized for Cypress devices. Warp EnterpriseTM
Timing Simulation
Warp Professional includes a post-synthesis timing simulator called Active-HDL Sim. Active-HDL Sim features a graphical waveform simulator that can be used to simulate PLD/CPLD designs generated in Warp Professional. The simulator provides timing simulation for PLDs/CPLDs and features interacPage 6 of 8

tive waveform viewing as well as graphical creation and editing of stimulus waveforms. The simulator also provides the ability to probe internal nodes, and automatically generate clocks and pulses. The version in Warp Professional has the ability to compare waveforms and highlight differences before and after a design change. In Warp Professional there is a maximum simulation time of 5 ms. Source-level simulation support and unlimited timing simulation are available with Warp Enterprise (CY3130 and CY3138). No matter what HDL you use for design entry, Warp Professional automatically creates a VHDL netlist to enable the use of the timing simulator. However, Warp Professional can generate both VHDL and Verilog timing models for third-party simulators to perform functional and timing verifications of the synthesized design. JAM/STAPL and programs the device. For FLASH370i, the JEDEC file is used directly to program the device. Warp Professional comes with an UltraISR Programming Cable and a Delta39K\Ultra37000 prototype board with a CY37256V 160-pin TQFP device and a CY39100V 208-pin PQFP device.[1] The JEDEC and Intel hex files produced by Warp Professional can also be used with any qualified third party programmer to program Cypress CPLDs. For more information on Cypress's ISR software see the ISR Programming Kit (CY3900i) data sheet.

Architecture ExplorerTM
The Architecture Explorer graphically displays how the design will be implemented on the chip. It provides a view of the entire device to show what memory elements and logic clusters have been used for what part of the design. This display gives the designer an idea of what resources are free. The Architecture Explorer allows you to zoom in multiple times. At maximum zoom it displays the logic gate implementation in each macrocell. The Architecture Explorer is available for PSI, Delta39K, and Quantum38K devices.

Timing Analyzer
The timing analyzer gives the time across any path as well as the breakdown of what steps are causing the timing delays. This tool does not simply display the general specification for the target device but a worst-case simulation of the actual path being taken through the device. When you highlight a path on the timing analyzer, the source and destination of that path are displayed on the Architecture Explorer. The timing analyzer graphical interface is available for PSI, Delta39K, and Quantum38K devices. However, for other devices the same information is available in a report file.
