I did two Assura RCX extractions with "coupling" and "de-coupling" extraction. The post-layout simulation gives pretty different result. The "de-coupling" one works fine, but not the "coupling" one. So which extraction is more accurate? Thanks.
hsim accuracy
I have tried to tweak HSIMMAXALLOWEDDV and HSIMTAUMAX, the final settling voltage does change. But I still cannot make it reach less than 100 uV error, which is needed in my simulation. Thanks.
hsim simulator
I am trying to simulate delta-sigma modulator with HSIM (it is said it is faster than Spectre). However when I look at the voltage across the sampling cap, there is around 0.5 mV numerical error (Spectre gives right result). It seems like the voltage keeps going to the right...
