*
* $Log: print_ucf.c,v $
* Revision 1.1.1.1 2003/11/04 23:34:57 mjames
* Imported into local repositrory
*
* Revision 1.5 2003/01/02 21:37:16 mjames
* Experiment on creating NOT_ROUTABLE_H and NOT_ROUTABLE_L
* properties on the nets so that pin jumpers can be made without a problem.
*
* Still need to sort out pin assignments made to these not_routable nets
* which will become legal in some cases so that pullups and pulldown
* pins can be used on the FPGA.
*
* Revision 1.4 2002/10/02 18:38:26 MJAMES
* Added semicolons to strings
*
* Revision 1.3 2002/09/16 11:03:31 mjames
* Made the output compatible with Xilinx expectation, after testing with
* Xilinx Alliance
*
* Revision 1.2 2002/09/09 10:12:02 mjames
* Moved pin remapping function to pin ident editing function from
* sorting pin name routine.
*
* Revision 1.1 2002/08/19 14:30:03 mjames
* Added the 'write UCF' command for
* listing pin assignments in Xilinx UCF file format
*
*
*
* This file contains routines for listing UCF files out for Xilinx Virtex
* (and CoolRunner!)
*
* **********************************************************************
* this file generates a list like this
