At this point RHEL 3 is the baseline for most EDA too vendors so that has the most compatibility. RHEL 4 and SLES 10 are becoming the standard but still not quite there.
This should go in the Linux section of the board.
I've seen it working at customers with the latest versions of Synopsys ( DC & Primetime ), Cadence NC-Verilog and Mentor ModelSim and Magma ..... so I think it is ok.
I know they had problems with previous versions of some of these program but
the current versions run ok
