I am using Spartan 3A industrial grade device. By default ISE assumes the device to commercial grade. The PAR file says "Initializing temperature to 85.000 Celsius. (default - Range: 0.000 to 85.000 Celsius)".
Timing analyzer also does the analysis against commercial temperature range.
How do I change the temperature range to industrial grade?
Any help would be greatly appreciated.

Adding a few more details:
Device to be used is XC3S200A-4FT256Industial
ISE version 10.1
I am able to see any device settings in ISE for timing which can differentiate between XC3S200A-4FT256Industial and XC3S200A-4FT256Commerial

Glad to have you on xilinx forums.
At present there is no options to select Industrial Grade devices in ISE.
There is no need for an Industrial grade options in ISE, since the commercial device does analysis for the worst case, which occurs at 85 degrees for commercial devices and 100 degrees for the industrial devices.

One more article which can be of help is http://www.xilinx.com/support/answers/11163.htm
Also observe that for commercial devices the temperature range which you can give in UCF is from 0 to 85 only. Even in the timing analyzer you have the range from 0 to 85 only. When you give a range out of this 0-85 the tool throws an out of range error.
Hope this helps. Let me know if it improved your understanding of the tool
