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

jdgriggs

 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.

    I was rather busy the last few days and so couldn't answer.

    If "which spectre" is not finding the executable, then it must be either that your UNIX path is wrong, or the permissions are wrong. Running the executable "spectre -W" could fail with command not found if /bin/ksh wasn't working, but "which" should just search for an executable in your path - so  I think your issue is going to be something simple (well it will be once we've figured it out!)

    First of all, the MMSIM path must be before the IC path - because otherwise you'll get the old spectre that came in IC5141 (which is really old) which is why various simulations fail, including monte carlo. Your models are probably incompatible with the old parser (MMSIM has been a separate release stream since late 2004).

    Please post what you get when you type "echo $path" (don't edit anything - just post it as is because you may hide some of the evidence by doing that).

    Check your MMSIM121 installation - does it have a "bin" dir? Is there a "spectre" within? Is it executable?

    This is really something that is very hard to debug over a forum - I'm sure it's something messed up in either your environment or your installation, but trying to work that out this way is very hard. What you're seeing seems very odd, and I'm positive it's a usage problem not a tool bug.

    Regards,

    Andrew.
