11.1 PlanAhead - Does PlanAhead support all UCF constraints?


Does PlanAhead support all UCF constraints?


PlanAhead supports most, but not necessarily 100%, of the UCF constraints. Xilinx is continually updating the tool to further improve its UCF support. 


If PlanAhead does not recognize a constraint, it will read and write it out to the exported UCF, but you will not be able to set it or change its value within the tool.
