General Description: Express currently writes an IPAD to the netlist when a BUFG is inferred at the port. However, if the BUFG is instantiated, then the IPAD is not inserted (contrary to what is shown in FPGA Express' schematic viewer). Schematics netlisted by ECS contain instantiated BUFG, thus most all schematics through the express flow will fail in MAP.
In Foundation ISE:
1. Right click on 'Implement Design' and select 'Properties ...' 2. Under the 'Translate Options' tab, select 'Create I/O Pads from Ports' 3. Delete the .ngd or .ngo file so that edif2ngd will run again.
These steps will execute the ngdbuild command with the -a swicth turned on.
