One of the more interesting developments in FinFET SoC design is the return of custom logic and ‘macros’. These large functional blocks include large bit count register trays, pulse latches, retention flops, and programmatic delay buffers. In FinFETs, they can play an essential role in optimizing power, performance and area. These Macros require process variation models (AOCV, POCV, LVF) just like any standard cell. However, because these cells are very large, it is impossible to use MC SPICE. Macro FX is the first practical solution for variation modeling of custom logic.
