Different bitstream produced by Quartus II v10.1 - Windows Linux

Hi,

I found on Altera documentation that passing from Windows to Linux the bitstream may vary.

From "Quartus II Handbook Version 11.1 Volume 2: Design Implementation and Optimization":

Any design change that directly or indirectly affects the Fitter has the same type of random effect as changing the seed value. This includes any change in source files, Analysis & Synthesis Settings, Fitter Settings, or Timing Analyzer Settings. The same effect can appear if you use a different computer processor type or different operating system, because different systems can change the way floating point numbers are calculated in the Fitter.

Now I really have to carefully analyse my design in order to eliminate timing violations that probably are causing my problems.

Did anybody have timing problems with a model created with Synopsys Synphony?
