一、引言为了设计VLSI电路,开发了各种技术.选择什么样的制造工艺(如CMOS、NMOS等)、布局类型(如门阵列、结构模块、PLA等)、电学设计类型(如静态、动态等)、对决定部件的最终性能及芯片设计周期起十分重要的作用.对于一个特定的定制或半定制设计来说。只能根据所设计电路的特点及所采用的制造工艺选择一种适当的设计方法,不存在适用于所有电路的固定设计方法.各种设计方法都有自己独特的设计思路,而各种设计思想均欲达到同一个目标:成本低、性能好、设计周期短.
I. INTRODUCTION In order to design a VLSI circuit, various techniques have been developed to select which manufacturing process (eg CMOS, NMOS, etc.), layout type (eg gate array, structural module, PLA etc.), electrical design type , Etc.) play an important role in determining the final performance of the part and the chip design cycle, for a particular custom or semi-custom design. Only according to the characteristics of the circuit design and the manufacturing process used to choose an appropriate design method, there is no fixed design for all circuits.A variety of design methods have their own unique design ideas, and a variety of design ideas Are trying to achieve the same goal: low cost, good performance, short design cycle.
