Hspice simulation and switches non-idealities

[pseudockb]

Hi, I would like to know whether Hspice can simulate the non-idealities like clock feedthrough and charge injection of the switches effectively. If so, how to do it? Thank you.

yes.
do .tr analysis

Make sure that the models you're using are charge conservative.

How to check if the models are charge conservative? Thanks

i hear hspice level 49 model can't modeling this effect very well.
