Soft TEMAC Won't Stop Instantiating BUFGs

Jump to solution

Hi all,

 

I'm trying to use the soft TEMAC on a S-6 in EDK 12.2, and having some problems with the automatic instantiation of BUFG/BUFGMUX resources.

 

I've got a flow where I will be bringing in clocks through BUFGs externally to the EDK system. This is a requirement for my system and cannot change. The TEMAC has a generic called C_INCLUDE_IO that can be set to 0, and this is supposed to make the TEMAC get instantiated without the internal global clock resources. This does not seem to be working - bringing in the netlists from EDK into PlanAhead, I see on the schematic view the clock resources being instantiated. These are the ones I want to avoid!

 

Is there a way to not have these global clock resources be used in the soft TEMAC? If they are inferred, how can it be made not to happen?
