These three are ASIC design domain is quite famous software vendors. Other company software relatively users less. Chinas huada company also provide ASIC design software (panda 2000); Another recent famous Avanti company, is originally in Cadence of several Chinese engineers created, their design tools can be comprehensive and Cadence company tools as legitimate, very suitable for deep-submicron IC design. Below the end-use for IC design software for some introductions.(1)design input toolsThis is a kind of any EDA software must possess basic functions. Like the Cadence of viewlogic composer, viewdraw, hardware description language VHDL Verilog HDL is main design, language, many design input tools support HDL. Like other Active - HDL and other input methods, including the design principle and state machines input methods, design FPGA/CPLD tools mostly as IC input methods, such as Altera Xilinx, provide development tools such as company Modelsim FPGA, etc.(2) design simulation workWe use EDA tools a maximum benefits can be verified design is correct, almost every company EDA products have the simulation tools. Verilog - XL, NC - Verilog used for Verilog simulation, Leapfrog used Analog to produce stats Artist used for simulation, VHDL Analog simulation. Viewlogic of simulators are: viewsim door level circuit simulator of speedwaveVHDL simulators, VCS - verilog emulator. There was little subsidiary companies of VHDL and product Model wave-tech Verilog double simulators: Model Sim. Cadence, Synopsys use is VSS. Now the trend is each big EDA companies have gradually in HDL simulator for a circuit verifying tool.(3) comprehensive toolsComprehensive tool will become door level nets table of HDL. This aspect Synopsys tools occupy the bigger advantage, its themselves as a Compile comprehensive industrial standard, it has another product called Compiler Behavior, can offer more advanced comprehensive.Another recent U.S. and worked out a software called Ambit, reportedly more effective than Synopsys software, can be integrated circuits, 50 million door faster. Earlier this year by Ambit Cadence, therefore company acquisitions Cadence abandoned its original integrated software Synergy. As the scale of the FPGA design is more and more big, each EDA company have developed for the FPGA design of integrated software, famouser are: Synopsys FPGA Express, the Cadence of Synplity, was Leonardo, this three FPGA integrated software accounts for most of the market.(4)layout and wiringIn IC design layout tools, wiring Cadence software is stronger, it has many products used for standard unit, gate array has can realize interaction wiring. The most famous is Cadence spectra, its original is used for PCB wiring, and later Cadence put it used for IC wiring. Its main tools are: Cell3, Silicon Ensemble - standard unit wiring manometers; Gate Ensemble - Gate arrays wiring manometers; Themselves Planner - layout tools. Every other EDA software development company also provide its own layout wiring tools.(5)physical validation toolPhysical validation tool includes layout design tool, territory validation tool, territory extraction tools, etc. This aspect is strong, its Cadence Dracula, Virtuso, Vampire such physical tools have many users.(6) analog circuits emulatorFront speak simulator is mainly directed against the digital circuit, for analog circuit simulation tools, commonly used SPICE, this is the only choice. Just choose different companies, like the MiceoSim SPICE, the Soft Meta PSPICE HSPICE etc. Avanti HSPICE is now company acquisitions. In numerous SPICE, as IC design, and its HSPICE simulation model, the accuracy is high.2.4 PLD design toolsPLD is a kind of questions by users according to need itself Logic functions of tectonic digital integrated circuit. At present basically has two big type: PLD and Complex Programmable Gate Array F
