EDA的发展及VHDL的应用 90s in 20 centuries, international last electronics and calculator technique more the forerunners nation, has been being actively investigating a new design method of the electronics electric circuit, and carried on an exhaustive change in the aspects of designing a method, tool wait, obtain huge success.At the design realm of the electronics technique, the application of programmable logic spare part(like CPLD, FPGA), have already got extensive universality, these spare parts brought tremendous vivid for the design of numerical system.These spare parts can pass a software plait a distance but as to its hardware structure and work the way carry on heavy Gou and make thus the design of hardware can like software design so convenient fast.The all these biggest changed a traditional numerical method, design process of the system design and design idea and promoted the EDA technical quick development. The EDA is an electronics design automation(the Automation of the Electronic Design) of abbreviation, design(CAD) from the calculator assistance at the beginning of 90s in 20 centuries, calculator assistance manufacturing(CAM), calculator assistance test(CAT) and calculator lend support to the concept of engineering(CAE) a development since then.The EDA technique is to take calculator as tool, design at EDA software terrace up, use the hardware description language HDL completion a design a document, then is of oneself completed logic to edit and translate, turn Chien, partitioned by the calculator, comprehensive, excellent turn, set up, cloth line with imitate really, until for particular target chip of proper go together with to edit and translate, the logic reflect to shoot with plait distance download etc. work.The EDA technical emergence, biggest raised efficiency and maneuverability of electric circuit design, eased to design of labor strength. These spare parts can pass a software plait a distance but as to its hardware structu
