5.30.11.2 ProASIC and ProASIC PLUS Placement Constraint File (GCF)

For ProASIC and ProASIC PLUS designs, you can export a GCF constraint file to get all of the constraint information. From the File menu, choose Export > Constraint Files, type a file name and click Save, and then select All GCF constraints in the Export GCF File dialog box. Blocks with locked placement constraints generate locked placement constraints, while the others generate initial placement constraints. You can edit a GCF file to remove existing

constraints or add new constraints. You must then import the modified GCF file as well as the netlist back into Designer. See Importing Source Files for more information about importing files.
