stitching results of two transient simulations

SoniaMK

Hi,

This might be a simple question for those who are skilled in spectre but it seems I can't figure out how to do the following. I want to run two transient simulation, the second one starting from a point in time where the first simulation finished or perhaps at a point of time somewhere during the run of the first simulation. Then I would like to stitch together the results of the first and second simulation. I hope this is possible and going from the first to the second simulation can be done quite seamlessly.

Thanks for your help.

    There are transient options called savefile, savetime, recover etc which do the job:

    
    22      saveperiod        Save the tran analysis periodically on the simulation
                              time.
    23      saveperiodhistory=no
                              Maintains the history of saved files. If yes,
                              maintains all the saved files. Possible values are no
                              and yes.
    24      saveclock (s)     Save the tran analysis periodically on the wall clock
                              time. The default is 1800s for Spectre. This
                              parameter is disabled in the APS mode by default.
    25      savetime=[...]    Save the analysis states into files on the specified
                              time points.
    26      savefile          Save the analysis states into the specified file.
    27      recover           Specify the file to be restored.
    

    If you run the first simulation with a savefile, and either savetime or save period or save clock to specify how often you want to write it, and then on the second simulation reference a file using recover, it will do what you want.

    Andrew.
