四、硅系统设计的CAD系统四(一)硅系统设计中CAD的主要内容如前所述,VLSI系统具有很高的复杂性.VLSI系统设计的关键是复杂性管理.硅系统的设计方法学的基本出发点即是有效的复杂性管理.为了实现硅系统的设计,必须开发建立在对应的设计方法学基础上的CAD系统.这种系统可以显著加快设计速度,可以在未进行实际制备前建立相应的模型对其功能及性能进行模拟,从而使设计一次成功的几率大为提高.根据VLSI的特点,通常芯片中一个错误就会使其失效.改正设计中的错误,需要重新设计,制版及流水制备,其代价十分昂贵.因此,CAD系统是VLSI设计中不可缺少的工具.随着复杂性的增大,CAD越来越成为VLSI设计的核心.
Four, the silicon system design of the CAD system Four (a) of the main contents of the CAD system of the silicon system design As mentioned earlier, the VLSI system has a very high complexity .VSLSI system design is the key to complexity management .Silicon system design methodology The basic starting point is effective complexity management.In order to realize the design of silicon system, it is necessary to develop a CAD system based on the corresponding design methodology, which can significantly speed up the design and can be established before the actual preparation The corresponding model to simulate its function and performance, so that the probability of a successful design greatly improved.According to the characteristics of VLSI, usually a chip error will make it invalid.To correct the design errors, you need to redesign, plate making and Pipeline preparation is expensive, so CAD systems are an indispensable tool in VLSI design, and as complexity increases, CAD becomes more and more the core of VLSI design.
