Please run `getSpectreFiles' or send the netlist, thespectre log file, the behavioral model files, and any other informationthat can help identify the problem to support(at)cadence.com. my spectre version is mmsim6.1. who know what's the problem ? thank you all!

  • Internal errors are indicative of an uncaught problem with the software. Usually there is some additional information which can help identify if it's a known problem by showing the context of the error in the spectre output log.

    However, you are using an old, no-longer supported version of MMSIM. My advice would be to install MMSIM72 (the latest release; it's possible you may need to request an update to your license file to get the latest version numbers) and then try again. There have been many, many improvements since MMSIM61 (since there have been 4 major releases since then), so it should be beneficial in all sorts of ways.

    If the problem still persists after updating your version, please follow the advice in the message and contact Cadence Customer Support, as it will then be indicative of an unresolved bug (which might be triggered by user error, who knows, so cust support may be able to suggest a workaround).
