So, can I include the '*.ic' got from Hsim to solve the DC noconvergence problem in Hspice? thanks

And, you must setup a high accuracy for hsim. Actually, I sometimes do in this way for postsimulation. Another way is to use uic to generate an IC. I think this should be the first choice.

Added after 2 minutes: sorry for mistaking 'change the step of the simulation to smller ' for 'chang the step of the simulation to larger'
