FATAL (CMI-2010): Assertion failed in file `bypassUtils.cc'

Clidre

Hello,

I'm facing the following problem, when I try to run a transient simulation.

FATAL (CMI-2010): Assertion failed in file `bypassUtils.cc' at line 1977.

FATAL (SPECTRE-21): Assertion failed.

The only thing that I empirically know is that it's a  hierarchy problem: a block in my system causes this problem, but if I remove the block and I put exactly what is inside that block, the simulation can run.

I also couldn't find the file  `bypassUtils.cc'

Has anyone experienced this?

I work with Virtuoso 6.1.5-64b

Thanks

  • More relevant would have been the simulator version number (at the  top of the spectre.out log file).

    There have been various assertion failures coming from this file over the years - I can't find an exact match though (the line number could change from subversion to subversion though).

    Which simulator version were you using? Could  you try using the latest hotfix of MMSIM13.1 or MMSIM14.1? If it still fails after that, you should contact customer support so that we can identify the problem and fix it.

    Kind Regards,

    Andrew

  • Thank you Andrew; my simulator version is

    Version 12.1.1.164.isr15 64bit -- 26 Oct 2013

    Can you explain in simple word what kind of problem is this one? Is an inner problem of Cadence? Can be a conflict with the technology files?

    Thank you very much!

    It's a bug in the simulator, albeit one that only shows up with certain data. It won't be a conflict with the technology files.

    Regards,

    Andrew.
