10、PGA Compiler II、 vExemplar Logic公司的LeonardoSpectrum、 vSynplicity公司的Synplify。 1.第三方工具軟件是對CPLD/FPGA生產(chǎn)廠家開發(fā)軟件的補 充和優(yōu)化，如通常認為Max+plus II和Quartus II對 VHDL/Verilog HDL邏輯綜合能力不強，如果采用專用的 HDL工具進行邏輯綜合，會有效地提高綜合質(zhì)量。 2021/6/730 ALTERA 公司的公司的EDA合作伙伴合作伙伴 2021/6/731 硬件描述語言：起源 v是電子電路的文本描述。 v最早的發(fā)明者：美國國防部，美國國防部，VHDL,1983 v

11、大浪淘沙，為大者二： VHDL 和 Verilog HDL v其他的小兄弟： ABEL、AHDL、System Verilog、System C。 2021/6/732 一個D觸發(fā)器的VHDL代碼例子 v- VHDL code position: p83_ex4_11_DFF1 v- v- LIBARY IEEE; v- USE IEEE.STD_LOGIC_1164.ALL; vENTITY DFF1 IS vPORT (CLK:INBIT; vD:INBIT; vQ:OUTBIT v); vEND ENTITY DFF1; vARCHITECTURE bhv OF DFF1 IS vBEG

12、IN vPROCESS(CLK) vBEGIN vIF CLKEVENT AND (CLK=1) AND ( CLKLAST_VALUE = 0) THEN v- 嚴格的CLK信號上升沿定義 vQ 2021/6/738 Compiler Netlist Extractor （編譯器網(wǎng)表提取器）（編譯器網(wǎng)表提取器） vThe Compiler module that converts each design file in a project (or each cell of an EDIF Input File) into a separate binary CNF. The filename

13、(s) of the CNF(s) are based on the project name. Example vThe Compiler Netlist Extractor also creates a single HIF that documents the hierarchical connections between design files. vThis module contains a built-in EDIF Netlist Reader, Verilog Netlist Reader, VHDL Netlist Reader, and converters that

14、translate ADFs and SMFs for use with MAX+PLUS II. vDuring netlist extraction, this module checks each design file for problems such as duplicate node names, missing inputs and outputs, and outputs that are tied together. v返回 2021/6/739 Database Builder(數(shù)據(jù)庫構建器 ): vThe Compiler module that builds a si

15、ngle, fully flattened project database that integrates all the design files in a project hierarchy. vThe Database Builder uses the HIF to link the CNFs that describe the project. Based on the HIF data, the Database Builder copies each CNF into the project database. Each CNF is inserted into the data

16、base as many times as it is used within the original hierarchical project. The database thus preserves the electrical connectivity of the project. vThe Compiler uses this database for the remainder of project processing. Each subsequent Compiler module updates the database until it contains the full

17、y optimized project. In the beginning, the database contains only the original netlists; at the end, it contains a fully minimized, fitted project, which the Assembler uses to create one or more files for device programming. vAs it creates the database, the Database Builder examines the logical comp

18、leteness and consistency of the project, and checks for boundary connectivity and syntactical errors (e.g., a node without a source or destination). Most errors are detected and can be easily corrected at this stage of project processing. v返回 2021/6/740 Logic Synthesizer vThe Compiler module that sy

19、nthesizes the logic in a projects design files. vUsing the database created by the Database Builder, the Logic Synthesizer calculates Boolean equations for each input to a primitive and minimizes the logic according to your specifications. vFor projects that use JK or SR flipflops, the Logic Synthes

20、izer checks each case to determine whether a D or T flipflop will implement the project more efficiently. D or T flipflops are substituted where appropriate, and the resulting equations are minimized accordingly. vThe Logic Synthesizer also synthesizes equations for flipflops to implement state regi

21、sters of state machines. An equation for each state bit is optimally implemented with either a D or T flipflop. If no state bit assignments have been made, or if an incomplete set of state bit assignments has been created, the Logic Synthesizer automatically creates a set of state bits to encode the

22、 state machine. These encodings are chosen to minimize the resources used. v返回 2021/6/741 Fitter（適配器） vThe Compiler module that fits the logic of a project into one or more devices. vUsing the database updated by the Partitioner, the Fitter matches the logic requirements of the project with the avai

23、lable resources of one or more devices. It assigns each logic function to the best logic cell location and selects appropriate interconnection paths and pin assignments. vThe Fitter attempts to match any resource assignments made for the project with the resources on the device. If it cannot find a

24、fit, the Fitter allows you to override some or all of your assignments or terminate compilation. vThe Fitter module generates a Fit File that documents pin, buried logic cell, chip, clique, and device assignments made by the Fitter module in the last successful compilation. Each time the project com

25、piles successfully, the Fit File is overwritten. You can back- annotate the assignments in the file to preserve them in future compilations. v返回 2021/6/742 Timing SNF Extractor(時序SNF文件提取器) vThe Compiler module that creates a timing SNF containing the logic and timing information required for timing

26、simulation, delay prediction, and timing analysis. vThe Timing SNF Extractor is turned on with the Timing SNF Extractor command (Processing menu). It is also turned on automatically when you turn on the EDIF Netlist Writer, Verilog Netlist Writer, or VHDL Netlist Writer command (Interfaces menu). Th

27、e Timing SNF Extractor cannot be turned on at the same time as the Functional SNF Extractor or the Linked SNF Extractor. vA timing SNF describes the fully optimized circuit after all logic synthesis and fitting have been completed. Regardless of whether a project is partitioned into multiple devices

28、, the timing SNF describes a project as a whole. Therefore, timing simulation and timing analysis (including delay prediction) are available only for the project as a whole. Neither timing simulation nor functional testing is available for individual devices in a multi-device project. Functional tes

29、ting is available only for a single-device project. v返回 2021/6/743 Assembler（匯編器） vThe Compiler module that creates one or more programming files for programming or configuring the device(s) for a project. vThe Assembler module completes project processing by converting the Fitters device, logic cel

30、l, and pin assignments into a programming image for the device(s), in the form of one or more POFs, SOFs, Hex Files, TTFs, Jam Files, JBC Files, and/or JEDEC Files. POFs and JEDEC Files are always generated; SOFs, Hex Files, and TTFs are always generated if the project uses ACEX 1K, FLEX 6000, FLEX

31、8000 or FLEX 10K devices; and Jam Files and JBC Files are always generated for MAX 9000, MAX 7000B, MAX 7000AE or MAX 3000A projects. If you turn on the Enable JTAG Support option in the Classic & MAX Global Project Device Options dialog box (Assign menu) or the Classic & MAX Individual Device Optio

32、ns dialog box, the Assembler will also generate Jam Files and JBC Files for MAX 7000A or MAX 7000S projects. After compilation, you can also use SOFs to create different types of files for configuring FLEX 6000, FLEX 8000 and FLEX 10K devices with Convert SRAM Object Files (File menu). vThe programm

33、ing files can then be processed by the MAX+PLUS II Programmer and the MPU or APU hardware to produce working devices. Several other programming hardware manufacturers also provide programming support for Altera devices. v返回 2021/6/744 Simulation Mode vFunctional Simulates the behavior of flattened n

34、etlists extracted from the design files. You can use Tcl commands and scripts to control simulation and to provide vector stimuli. You can also provide vector stimuli in a Vector Waveform File (.vwf) or a text-based Vector File (.vec), although the Simulator uses only the sequence of logic level cha

35、nges, and not their timing, from the vector stimuli. This type of simulation also allows you to check simulation coverage (the ratio of output ports actually toggling between 1 and 0 during simulation, compared to the total number of output ports present in the netlist). vTiming Uses a fully compile

36、d netlist that includes estimated or actual timing information. You can use Tcl commands and scripts to control simulation and to provide vector stimuli. You can also provide vector stimuli in a Vector Waveform File (.vwf) or a text-based Vector File (.vec). This type of simulation also allows you t

37、o check setup and hold times, detect glitches, and check simulation coverage (the ratio of output ports actually toggling between 1 and 0 during simulation, compared to the total number of output ports present in the netlist). vTiming using Fast Timing Model Performs a timing simulation using the Fa
