Hi, Andrew, Thanks for your reply. My icfb version is 5.10.41. I actually don't understand the mechanism of corner tools. I have seen two typical cases of corner tool. 1) In CIW window, there is something like" Delete psf data in /home/wangrui/simulation/filter_spmod_tb/spectreVerilog/config/psf. ... Corner simulation #15/25 finished with status=ok, corner="slow_hot2" ... Delete psf data in /home/wangrui/simulation/filter_spmod_tb/spectreVerilog/config/psf. ... Corner simulation #16/25 finished with status=ok, corner="typ3" ... " The output log looks like a normal simulation. but refreshing itself after a new corner begins.
2) nothing in CIW window. The output log has something like " *********************** Alter Group `fast_best' *********************** device "I453.I496.M123.m0" is altered device "I453.I496.M124.m0" is altered device "I453.I496.M132_1.m0" is altered device "I453.I496.M132_2.m0" is altered device "I453.I496.M132_3.m0" is altered device "I453.I496.M18.m0" is altered ....... " The first one is very robust but the second one is prone to failure,.
My simulation output used to be like case 2. It refuses to work and that's why I posted here for help. Then I deleted some variables and used a even larger circuit, the simluation looks like case1 and it works. But I am still confused.
