Resume ModelSim sim from wlf?

    Hello,

    Sometimes while running very long simulations in the background I need
    to reboot. In cases like this it would be nice to be able to pause the
    simulation and save the dataset so I can continue later. I am familiar
    with saving the dataset to a wlf and then opening the dataset for
    viewing. I've tried reopening the dataset in this way, but I don't see
    if it's possible to resume the sim at the exact time point I left off.
    Iirc, when I reload the sim and open the wlf, it will start running
    from t=0. Is there a way to continue a simulation?

    Thanks,
    -Brandon

    Hi Brandon,

    This is called checkpoint and restore and AFAIK only supported on SE/Questa.
