downgrading RHEL to support IC 5141

knight499

Hello! Wondering if anyone else had to downgrade RHEL on a new workstation to support both IC 5141 and IC 61? What were the experiences with this? 

Seems quite a few foundries are still in IC 5141, listed in the supported platform matrix as requiring RHEL 4 / EOLd. New workstations are coming with RHEL 6 installed by default which isn't supported yet even for IC 61. So, to choose RHEL 5 even though Cadence doesn't officially support IC 5141 on it, or go down to RHEL 4 and be unsupported by RHN if there are issues in the downgrade such as missing drivers or libraries.

Any success stories or issues with taking either path would be appreciated. This is a Xeon X5687 with 24GB RAM, and there is plenty of disk space.

Cheers

  • Thanks Andrew! This is a big help especially on the networking. 

    The base OS on most systems shipping with Red Hat is now RHEL6. Even the foundries with kits that run on IC 6 don't necessarily support IC 615 ISR12, since this is the latest and greatest. So, two VM is for two PDK one with IC 514 (RHEL4) and one with IC 613 (RHEL5). I'm reluctant to remove the RHEL6 since it's coming soon. 

    Now, I was asking for more information about the implications of "not supported."Yes, extremely helpful that you work for Cadence even.

    If the designers can't get support for basic simulation questions because of using RHEL5, then I would think it's too risky. I mean, we submit that the simulation won't converge for example because itol is not set correctly. And, the SR gets autoclosed because of wrong OS. That would be not cool. 

    But, if not supported meant that if there is something obviously OS related like a simulation crashes with lib.so.X11 or something then the help ticket gets closed until we test on supported OS. That would be palatable,

    Would it be the former or the latter? 

    Cheers,
