Error found by spectre during circuit read-in--can't find process.scs library

Hi everyone

I've recently have come across an error that have not come across before and i'm hoping one of you may have an answer for me. For some unapparent reason the input.scs cannot not seem to find my process.scs libs. This just occured but previously Cadence has been running fine.

here is what the output files gives

I don't understand what could be causing this error all of a sudden any insight you can offer would be appreciated.

Also, I think cmrf7sf is not compatible with IC610. Theres a post on the MOSIS user group regarding this, although it is about a year old now. Check your cdslib release notes to verify what version of IC they used to test the PDK. I'm using cmrf8sf and I'm pretty sure they're still testing on IC5141. For the sake of simplicity, why not use (if you have it) allModels.scs instead of design.scs, process.scs and fixed_cor.scs? (I havent used 7sf, i'm assuming the kit structure is the same as 8sf).
Updating IBM kits can be tricky. You have the rel@ link in your pdk folder so you are using the latest files... you mentioned that you patched your kit recently, did you start having these problems after doing so? try making rel point to an older kit version and see if it works. if it does, then something went wrong when patching your kit. You don't need to define section for the model files, your .cdsenv should read:
spectre.envOpts modelFiles “../rel/Spectre/models/design.scs ../rel/Spectre/models/fixed_corner.scs
../rel/Spectre/models/process.scs”
spectre.envOpts includePath string "../rel/Specre/models"
of course you would make your own site-specific adjustments for the paths.
Can you check your spectre version? type "spectre -W" in terminal. Maybe you have the correct version of MMSIM but if its not defined in the PATH before IC, you'll still be using spectre from the IC stream.

Check this link.. its the weblog of the system admin of UofChicago's EE dept. S/he details how they troubleshoot cadence and mosis kits. https://hepblog.uchicago.edu/hep/hep4/
