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.

I'm presuming you are talking about the feature of adding migration devices in the Pin Planner to make sure pin assignments are valid across the multiple devices.

Probably the best way to implement this would be to use the revisions feature in Quartus. Create a new revision of your project based off the current project and then switch the device in the new revision. You can always switch back to the original revision.

I'm not sure if you'll lose the I/O assignments when you change the device, but before doing so, you can export the I/O assignments from the Pin Planner and then import them back in after changing the device (kind of like a backup).

Hi sstrell

I am specifically hoping to avoid creating a project variant -- how about manual edit the QSF file:

### pick active device
#set_global_assignment -name DEVICE 10AX027H4F34E3SG
#set_global_assignment -name DEVICE 10AX032H4F34E3SG
#set_global_assignment -name DEVICE 10AX048H4F34E3SG
set_global_assignment -name DEVICE 10AX066H4F34E3SG
#...
set_global_assignment -name DEVICE_MIGRATION_LIST "10AX066H4F34E3SG,10AX057H4F34E3SG,10AX048H4F34E3SG,10AX032H4F34E3SG,10AX027H4F34E3SG"

Regards

Steve

    I'm not sure what you mean by a project variant. The revisions feature is still a single project (single .qpf file) with multiple settings files (.qsf files). When you switch revisions (pop-up list in toolbar or Revisions dialog box), you're just switching between the .qsf files so you don't have to go in and edit them manually like this.

      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
