请问要怎么操作？

可以在spectre帮助文档中搜索"Savestate - Recover"相关章节, 以下是一些介绍

Savestate - Recover (savestate)
Description
Savestate-Recover is a transient analysis feature. It is a replacement for Checkpoint-Restart
capability.
The Checkpoint-Restart capability saves only the circuit solution for the timepoint at which the
simulation is interrupted. Because there is no history information saved for the circuit,
glitches, convergence issues, and inaccuracies can result when the simulation is resumed.
The Savestate-Recover feature saves the complete state of the circuit, avoiding these issues.
Savestate-Recover provides the following functions:
■ You have the option to save circuit information at set intervals or at multiple points during
transient analysis. If the simulation halts unexpectedly, you can restart transient analysis
from any saved timepoint.
■ You can experiment with different accuracy settings over different transient time periods
to obtain the optimal speed/accuracy trade-off.
