5.2i CPLD Fitter CoolRunner XPLA3 - A fatal error occurs when auto-slew is used (ISE "Timing-driven slew rate" option)


General Description: 

When I use the Timing-Driven Slew Rate option, a fatal error similar to the following is reported:  


"CPLDFIT caused an invalid page fault in module KERNEL32.DLL at 0167:bff9dfff.

To work around this issue, use the "Fast" or "Slow" options rather than the "Timing-Driven" option when selecting the default slew rate. 


This will be fixed in the 6.1i software release.
