3.1i - Spartan-II - Why did the Spartan-II speed files change after I installed a service pack?

Description

Keywords: timing, speed, speed files, Spartan-II

Urgency: Standard

General Description:
I have installed a service pack on top of an existing one, and the timing numbers for my application have changed slightly. (This problem occurs if you install 3.1i Service Pack 7 or older over another SP.)

Solution

Lab testing has revealed that the speed files in software versions previous to 3.1i Service Pack 8 do not have the most accurate numbers.

This problem is fixed in the latest 3.1i Service Pack, available at:
http://support.xilinx.com/support/techsup/sw_updates.
The first service pack containing the fix is 3.1i Service Pack 8.
