Release 12.2 - par M.63c (nt64) Copyright (c) 1995-2010 Xilinx, Inc. All rights reserved. Wed Apr 30 19:05:22 2014 INFO: The IO information is provided in three file formats as part of the Place and Route (PAR) process. These formats are: 1. The <design name>_pad.txt file (this file) designed to provide information on IO usage in a human readable ASCII text format viewable through common text editors. 2. The <design namd>_pad.csv file for use with spreadsheet programs such as MS Excel. This file can also be read by PACE to communicate post PAR IO information. 3. The <design name>.pad file designed for parsing by customers. It uses the "|" as a data field separator.
