Resuming transient simulation in Spectre (Read 5159 times)

by default transient simulation will save checkpoints which are spaced 1800 seconds apart (this can be changed by setting the "saveclock" transient option). If the checkpoint file exists, then you can run from that point by setting recover on (in ADE under Setup->environment->recover) or spectre option -recover.

do spectre -h
or spectre -h tran
or refer to the spectre manual for more information.

Better still use the capability in recent versions of spectre (I think it was introduced in MMSIM61, although it may have been MMSIM60) to save "state". There are a number of options to the tran analysis which allow you to specify times to save the state, or the wall clock period to save the state (similar to the checkpoint options that Alan suggested). As with checkpoint, these may be recovered using the recover options.

The benefit is that this saves a complete state, and tends to be more robust in restarting.

Regards,

Andrew.
