Generate only partial bitstream not the full bitstream

In Partial Reconfiguration flow, I've noticed that when I compile a Persona Implementation, it generates both the full bitstream(.sof) and partial bitstreams for all PR partitions(.pmsf and .rbf...

    The .sof files for each implementation revision allow you to test your design with that persona in place without having to perform a PR first. If you don't use them, just ignore or trash them.

    Once you have a .pmsf file for a partition, use Convert Programming Files to create a .rbf for it. Your workaround is saying that partition_2 is a SUPR (static update PR) region. Normally a .rbf file is created for a SUPR region even though you can't use that .rbf to PR a SUPR region during runtime (why it's call static). I guess I'm not sure what your goal is with (2).

2. is resolved by having

set_instance_assignment -name RBF_FILE_GENERATION_FOR_SUPR OFF -to pr_partition_2

in .qsf file. I am not sure why the it is RBF_FILE_GENERATION_FOR_"SUPR", but it seems to exclude

pr_partition_2 when generating partial bitstreams.

Quartus is still generating the full bitstream(*.sof), so 1. is not resolved yet.
