ID:274004 Net "<name>" has no sources. Ignoring net during synthesis.

CAUSE: The EDIF Input File (.edf) contains the specified net but does not include any source for the net. This message can also occur if you specify incorrect names for the VCC and GND signals that are used in files generated by an EDA design entry or synthesis tool.

ACTION: Make sure you specified correct names for the VCC and GND signals so that the specified net has a source. If those settings are correct, try to correct the source design file so that the specified net has a source. In general, it is better to correct only the source design file rather than the EDIF Input File. If you prefer to edit the EDIF Input File, make sure it conforms to the format for EDIF version 2 0 0. If necessary, consult your EDIF manual.
