selecting a bufgmux

Jump to solution

Hello,

 

This is a conceptual question so don't worry that there's no code attached. 

 

I was wondering, is it possible to add a constraint in the ucf file that will tell the map and/or place and route tool which bufgmux to use for a given clock input? For the record I am using verilog with ISE 14.7.

 

Thanks,

Kevin
