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

  • This is a single workstation which will hold the license file and any VM would be installed on it.Let's say I keep the base RHEL 6 and install 1-2 VM to support PDK and IC versions. I apreciate this as the safe and approved path and I have some questions. 

    The license server can't run on a VM. How do I get the base OS let the VM access the license? I'm thinking of using VirtualBox, has anyone done this and was it a seamless part of the install or was further configuration needed?

    Does anyone have experience with performance hit due to serving license from base operating system of same hardware? I've seen another thread on installing VM but not a consensus.

    Anyone running 2 VM to support 2 different PDK/IC together with license server on the same base machine? 

    I'm getting a different, unofficial recommendation from elsewhere to go with RHEL 5 as the base OS. Apparently no one is having issues with IC 5141 in RHEL 5 except for with cdnsdoc. Would Cadence refuse to provide support if running IC 5141 on RHEL 5? I guess we could still test any issues that did come up with a VM RHEL 4 test environment if necessary.

    Thanks, all, for sharing your expertise on this!
