Hello,

I see Chip Planner regularly working in QPP 22.4 with different designs.

Regards,

Frank

    Hi FvM,

    Thanks for tests. It turned out something has happened in device migration settings between 22.3pro and 22.4pro.

    I use Cyclone 10CX105YF780E5G and migration device 10CX150YF780E5G. Even when I start new design with migration set, chip planner fails. Without migration, it works fine.

    BUT there is a caveat, once you set migration and remove it later through menu, quartus still keeps in QSF file

    assignement

    set_global_assignment -name DEVICE_MIGRATION_LIST 10CX105YF780E5G

    which cause chip planner fail. It must be manually deleted from QSF.

    As I need device migration, I need to keep this assignment

    So, I consider this behaviour a bug in quartus

    Regards

    Peter
