1.2.2. Assigning a Pin
To assign a signal to a pin or device location, use the Tcl command shown in this example:
set_location_assignment -to <signal name> <location>
Valid locations are pin location names. Some device families also support edge and I/O bank locations. Edge locations are EDGE_BOTTOM, EDGE_LEFT, EDGE_TOP, and EDGE_RIGHT. I/O bank locations include IOBANK_1 to IOBANK_n, where n is the number of I/O banks in a device.
