做电路仿真时
工艺角有ss,tt,ff,fs,sf
温度 -40, 27, 85
还有电压VDD(1-a%),VDD ,VDD(1+a%)
请问大家,这3组变量,大家是怎么组合仿真的?貌似组合有好多种

should run all the combinations. For certain performance, if you know which combination is the best case and which one is the worst case, just run the best case, worst case, and typical case (3 cases).
如果每个case都仿的话就有5*3*3=45种case
看需要吧,要都仿,工作量确实也大了点
学习了
好像小编的corner不太全
1.8v mos model * 3.3v mos model * res model * cap model * vdd * temp
不考虑typ的情况,有 4(ss,ff,sf,fs)*4(ss_3v,ff_3v,sf_3v,fs_3v)*2(min_res,max_res)*2(min_cap,max_cap)*2(vdd..)*2(-40,125)=256
我曾经编过一个4096的corner,很遗憾仿真器干不了这个活
