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

  • Marion,

    IC613 should also run on RHEL4, so I don't think you necessarily need an RHEL5 VM.

    Nothing gets auto-closed because of the wrong OS. Simulation convergence problems and usage questions would be dealt with as it's almost certainly nothing to do with the OS being used. And anyway, recent versions of MMSIM require you to be using RHEL5 or later (so that might be another reason for running IC5141 on an "unsupported" OS - because otherwise if you want to use IC5141 with MMSIM10.1 you'd have to use remote simulation so you could run both on a supported OS (icfb on your RHEL4 VM, and MMSIM on the physical host, maybe).
