(Ask a Question)Description
This Tcl command exports the I/O Physical Design Constraint (*.pdc) File. You can export the I/O PDC file from Constraint Manager > I/O Attributes or Constraint Manager Floor Planner or from File menu. Constraints can be exported to PDC file for reference, but must be manually added to an existing PDC or imported via the Constraints Editor for the changes to affect the final paced and routed design. The exported file has *.pdc file name extension. Before exporting, you need to run 'Place and Route'.

Example
The following example exports information about all of the physical design constraints (I/O constraints, I/O Banks, routing constraints, region constraints, global and local clocks). Created both "sd_io1.pdc" and "sd_io2.pdc" files.
export_io_pdc -file {./sd_io1.pdc} -file {sd_io2.pdc}
