ModelSim EE/SE Command Reference ModelSim Commands CR-53
checkpoint
The checkpoint command saves the state of your simulation. The checkpoint
command saves the simulation kernel state, the vsim.wav file, the list of the HDL
items shown in the List and Wave windows, the file pointer positions for files
opened under VHDL and the Verilog $fopen system task, and the states of foreign
architectures. Changes you made interactively while running VSIM are not saved;
for example, VSIM macros, command-line interface additions like user-defined
commands, and states of graphical user interface windows are not saved.
Once saved, a checkpoint file may be used with the restore command
(CR-134)
during the same simulation to restore the simulation to a previous state. A VSIM
session may also be started with a checkpoint file by using the vsim -restore
command
(CR-208).
