CR-134 ModelSim Commands ModelSim EE/SE Command Reference

restore

The restore command restores the state of a simulation that was saved with a

checkpoint command

(CR-53) during the current invocation of VSIM (called a

"warm restore").

The items restored are: simulation kernel state, vsim.wav file, HDL items listed in

the List and Wave windows, file pointer positions for files opened under VHDL

and under Verilog $fopen, and the saved state of foreign architectures.

If you want to restore while running VSIM, use this command. If you want to start

up VSIM and restore a previously-saved checkpoint, use the -restore switch with

the vsim command

(CR-208), this we call a "cold restore".

Note: Checkpoint/restore allows a cold restore, followed by simulation activity, followed by a warm

restore back to the original cold-restore checkpoint file. Warm restores to checkpoint files that were not

created in the current run are not allowed except for this special case of an original cold restore file.
