OpenPCF

The OpenPCF command opens an existing physical constraints file (PCF). This command applies only to FPGAs. The order of the constraints in the PCF file is reflected by the Timing Analyzer.

Loading a new physical constraints file causes the Prorating Options to be reset to the values specified in the last PCF file you loaded. If the PCF file does not contain Prorating Options preferences, the worst case values are used.

This command is equivalent to the File Open Physical Constraints menu command.
