ac simulation question?

[xiongshoufen]

anyone can tell me how to do ac simulation with 130ms dc operation point.
that is to say , how to do ac simulation with some moment dc operation point. thanks!!

Run a transient simulation up to 130ms, and save the final operating points (ie at 130ms) to a file. There is a "writefinal" in the simulation option.

Then run the ac simulation, by input the file as initial condition.
Not sure if it will works.
