Auto-Assigned Ports To Device Pins

This compiler hint occurs when there is a port on the schematic and there is no FPGA_PINNUM placement constraint specified for the design’s configuration. The system automatically assigns a pin number to this port based on the device you have selected. The message is displayed in the Messages panel in the following format:

Port PortName will be automatically assigned to a Device Pin

where

PortName is the name of the offending port (e.g. LEDS[7..0])                                                                        

Default Report Mode

Warning

Recommendation

Assign a placement constraint in the constraint file for that port by using FPGA_PINNUM with the appropriate device pin(s).
