Hi Ryan

Sorry for late response.

Can you try to remove those board trace model assignment with OUTPUT_IO_TIMING_NEAR_END_VMEAS and OUTPUT_IO_TIMING_FAR_END_VMEAS? Those assignment might not supported by certain devices.

Cross family device migration has no direct flow. We have to review from various aspect such as pin assignment, IP migration, parameter setting and etc. The suggested migration is vertical migration within the same family which can be referred to datasheet of each family.

Thanks.
