Inter-Path Competition (Beginner Question)

First I believe you have to explicitly code the duplicate registers. This means that if you have a register called test_reg that fans out to 20 destinations you would create extra copies that are logically identical but are wired up to different destinations (test_reg_a, test_reg_b, etc). You have to code the fanouts yourself.

Then go into Assignments -> Settings -> Compiler Settings -> Advanced Settings (Synthesis). There's a setting in there called "Remove Duplicate Registers" that is enabled by default. You need to disable that so that your duplicate registers don't get optimized away.

I believe this is the best way to handle this. If not then hopefully someone else will chime in.
