ID:271007 Can't process assignment. Attribute format is illegal -- multiple source values "<name>" specified for assignment using '-from' option. Use legal format for ALTERA_ATTRIBUTE assignment.

CAUSE: You specified the ALTERA_ATTRIBUTE assignment, but you specified multiple assignment source values using the '-from' option. The Quartus Prime software cannot process assignments with multiple source values.

ACTION: Modify the ALTERA_ATTRIBUTE assignment so that it contains only one source value.
