Simulation continuing from where the previous one left off.

[dati_remo@libero.it]

I accidentally simulated my large design for 65ns instead of the required 75ns.
Is there a way to simulate a design for the time 65ns to 75ns, starting from the
previous simulations' state?

Thanking you,

Dati

If you are using spectre, there is, look for "checkpoint" in your spectre docs. But be careful: we have seen differences between the resumed simulation and the "real thing". Possibly caused by device models, because the checkpoint contains information about currents & potentials (charges, fluxes) in the network, but no info about the state of compact models.

Any expert here can confirm that compact models have a state? that they are not instantaneous and can show some transient effects ?
