ID:274027 Can't read format of location assignment "<name>" associated with assignment "<name>"

CAUSE: An EDIF Input File (.edf) in the current project contains the specified location assignment; however, the Quartus Prime software cannot process this assignment. This error may occur if the location assignment does not follow the legal format <chip name>@<pin number>.

ACTION: Regenerate the EDIF Input File in the appropriate EDA tool. If you prefer to edit the EDIF Input File, make sure that the file conforms to the format for EDIF version 2 0 0. If necessary, consult an EDIF manual.
