15.6.1.1 Using PDC Files (IGLOO, Fusion, ProASIC3, and Axcelerator only)

Any constraint that you can enter using ChipPlanner, you can also enter using a Physical Design Constraint (PDC) file. A PDC file is a Tool Command Language (Tcl) script file specifying physical constraints. This file can be imported and exported from Designer. PDC files replace the PIN file for the Axcelerator family.
