在用PT生成的sdf文件和PR以后的得到的门级网表文件进行VCS后仿真的时候,在跑best和worst两种情况的时候,报了很多有关SDF Warning主要集中在以下两种:
SDF Warning:Negative limit Cannot be used in simple timing check,it's replaced by 0.Please use $recrem.
SDF Warning:Negative IOPATH Delay A1 to ZN is replaced by 0.This negative value cannot be handled with switch -negdelay.Please check SDF files.
请大家看看该如何解决或者说这个可以忽略?
