I have a design with PPC. I am not using in-built hard emac in the device. When I run through MAP in ISE, I get
the following error message:
ERROR:LIT:298 - DCREMACWRITE pin of PPC405_ADV symbol
................./PPC405_ADV_i can only drive pin DCREMACWRITE of an EMAC.
Make sure -u option (Trim Unconnected Signals) in MAP properties is disabled.
