XST keeps removing some of my input pins. I have used the LOC attribute in both the VHDL itself and in the .ucf file to no avail. After PAR, the pins declared in the port declaration (and LOCed to specific pins) have not been routed to a pad.
The inputs ARE used by latching into a register that is later read. Any thoughts on why XST is removing them and how to make it stop? Thx-Matt
