ModelSim EE/PLUS Reference Manual Simulator Command Reference

restore

The

restore

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

checkpoint

command (p291) during the current invocation of VSIM, this we call

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 (p91), 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.

Syntax

restore

[-nocompress] <filename>

Arguments

-nocompress
