Effective design To achieve an effective design,a designer needs to explore the design space for tradeoffs of competing design objectives. The following are some of the most critical design objectives the Designer needs to consider: >Geometric chip size Area(规模，成本) >Transistor count Critical path delays(带宽) Gate-equivalents Testability(可测性) Power dissipation(功耗) 2021/1/13 ASIC Design,by Yan Bo
