Saving and Continuing a Simulation (ModelSim)

It is possible to save the state of a simulation at the end of a successful run in a .krn file. In case of a co-simulation, Twin Builder also prompts ModelSim to save its state in a checkpoint file. The checkpoint file name generates based on the name of the ModelSim top level source file name.

Similarly, when a previously saved .krn file is loaded, Twin Builder detects the presence of a co-simulation model and prompts ModelSim to load the saved checkpoint file.

Note that setup steps still must be followed before restoring from a saved simulation.
