In ISE 11.1 schematic files are written to a new XML-based format. The new format will be used when creating a new schematic file or when saving an existing schematic. An issue has been found in the schematic reader code where CR-LF characters are being handled in an inefficient way.
A patch for this issue is available at:
http://www.xilinx.com/txpatches/pub/swhelp/ise11_updates/ar32786_projnav_11.zip The patch is applicable to ISE 11.1 on Windows 32-bit, Windows 64-bit, Linux 32-bit, and Linux 64-bit platforms.
COMPATIBILITY:
This Tactical Update is compatible with ISE 11.1 and will no longer be needed as of ISE 11.2.
INSTALLATION:
Please extract to the root of your ISE 11.1 installation directory (for example, C:\Xilinx\11.1\ISE).
