PIN2UCF Overview
PIN2UCF is a command line program that generates pin-locking constraints in a User
Constraints File (UCF) by reading a placed, or placed and routed NCD file for FPGAs or
GYD file for CPLDs. PIN2UCF writes its output to an existing UCF. If there is no existing
UCF, PIN2UCF creates one.
