【正文】 matic wiring using tools, its newest edition is Protel DXP, now monly used are Protel99SE, it is a plete omnidirectional circuit design system that incorporates electricity principle chart drawing and analog and digital circuit of mixed signal simulation, multilayer PCB design (including printed circuit board automatic layout wiring), programmable logic device design, chart formation, circuit form generation, support macros operation, etc., and has are/Server (customer/service system structure, but also throws in some other design software file formats, such as ORCAD, PSPICE, EXCEL, etc. Use multilayer printed circuit board, which can realize the automatic wiring high density of the PCB 100% cloth tong rate. Protel software powerful (at the same time with circuit simulation function and PLD development function), friendly interface, easy to use, but it is the most representative is circuit design and PCB design. 10 IC design software IC design tools many, including according to market the share of row Cadence, behavior was little and Synopsys. These three are ASIC design domain is quite famous software vendors. Other pany software relatively users less. China39。 MMICAD LiveWire, Edison, Tina Pro who Spark etc. The following simple introduced the first three software. (1) the SPICE Simulation done account (vehicle) : Emphasis is launched by the university of California, Circuit analysis Simulation software, the 1980s the world the most widely applied Circuit design software, 1998 was designated as the American national standards. In 1984, the United States MicroSim pany launched microputer version PSPICE based on the SPICE (Personal SPICE). Now use morer, can say is among similar products, it is the most powerful analog and digital circuit hybrid simulation EDA software, in domestic monly used. The latest to release the version. It can undertake various kinds of circuit simulation, incentive establish, temperature and noise analysis, simulation control, waveforms output, data output, and in the same window inside also showed analog and digital simulation results. No matter what kind of device which circuit simulation, all may obtain accurate simulation results, and may independently establish ponents and ponent libraries. (2) The latest version of EWB multiSIM (add) software: is Interactive Technologies Ltd in 20th century rolls out circuit simulation software. Its newest edition is multiSIM7, currently in widespread use is multiSIM2021, relative to other EDA software, it has more image intuitive manmachine interface, especially its instrument repository each instrument operation and real in a real experiment instrument, but it do not differ pletely to module circuit of hybrid simulation function but no less, can almost 100% emulation produce real circuit, and it results in instrument repository also provides a multimeter, signal generator, watt table, dual tracer oscilloscope (for multiSIM7 also has four steps oscilloscope), potter instrument (quite 9 actually of sweeping frequency instrument), words signal generator, the logical analyzer, logic transition meter, the distortion degree analyzer, spectrum analyzer, work analyzer and voltmeter and ammeter etc instrumentation. Also provides our daily mon various modeling accurate ponents, such as resistors, capacitors, and inductors, triode, diodes, relays, SCR, digital tube etc. Analog integrated circuits have all sorts of operational amplifiers, other mon integrated circuits. Digital circuit has 74 series integrated circuits, 4000 series integrated circuits, etc also support the homemade ponents. MultiSIM7 also has iv analyzer (equivalent to realworld transistor characteristics shown instrument) and Agilent signal generator, Agilent multimeter, Agilent oscilloscope and dynamic logic flat pen etc. At the same time it also can VHDL simulation and Verilog HDL simulation. (3) MATLAB one of the product family: they have many characteristics is facing the specific application of toolbox and simulation block, contains the plete function sets used to image signal processing, control system design, neural work, and other special application analysis and design. It has a data acquisition and report generation and MATLAB language programming generate independent C/C + + code, and other functions. MATLAB product family has the following features: data analysis, Numerical calculation and symbols, engineering and scientific drawing, Control system design, Digital image signal processing, Financial engineering。 MultiSIM7。 7 EDA Technology And Software EDA is Electronic Design Automation (Electronic Automation) is the abbreviation of themselves, in the early 1990s from puter aided Design (CAD), puter aided manufacturing (CAM), puter aided testing (CAT) and puter aided engineering (CAE) development of the concepts and e. EDA technology is on the puter as the tool, the designer in EDA software platform, with VHDL HDL finish design documents, then by the puter automatically logic pilation, reduction, division, prehensive, optimization, layout and wiring and simulation for a particular goal chips, until the adapter pilation, logic mapping and programming download, etc. 1 EDA technology concepts EDA technology is in electronic CAD technology developed on the basis of puter software system by means of puter for working platform, shirtsleeve application of electronic technology, puter technology and information processing and intelligent technology to the latest achievements of electronic products, the automatic design. Using EDA tools, electronic stylist can be from concept, algorithm, agreement, etc, begin to design your electronic system a lot work can be finished by puter and electronic products can be from circuit design, performance analysis to design the IC territory or PCB layout
