ID:274007 Net name "<name>" is used multiple times, but should be used only once

CAUSE: The EDIF Input File (.edf) contains a name for a net that was already assigned to another net. This problem may exist in the source design file. 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. If those settings are correct, try to correct the source design file. 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.
