Official quick method of switching between devices in device migration list

what is the official but quick method for switching between devices in the device migration list? I do hope it doesn't involve creating a whole new project variant for each target device as this wil...

    That's your call then. I thought the only thing you wanted was to quickly switch devices and I/O assignments, but if there are other things that may change and need to match between the different revisions, then it might not be the best way to go.

    You could instead use Tcl scripting in the .qsf for this type of stuff.

Hi sstrell

I would prefer 1x QSF file if possible -- the device migration list ensures everything is otherwise compatible across the prospective devices so why have multiple QSF files -- say for instance we discover an transceiver assignment change improves transceiver performance then we would have to edit multiple QSF files (via Quartus GUI of course) to keep them in synch functionally

Regards

Steve

      Switching devices is easy in the GUI (Assignments menu -> Device). It's just that many assignments get blown away when you switch devices and you also may have to regenerate IP.

        Hi sstrell certainly that was what I was concerned about -- I did an experiment and it appears that the only assignment that gets stomped in QSF is the DEVICE_MIGRATION_LIST which is easy enough recreated -- regenerate the the QSYS and it seems to work -- will use this method with extreme caution going forward...
