FATAL (CMI-2010) in transient simulation

GuanghuaShu

My spectre version is: Version 15.1.0.644.isr13 64bit -- 22 Oct 2016

Error information as following:

Internal error found in spectre at time = 35.7142 ps during transient analysis `tran'.
Encountered a critical error during simulation. Submit a Service Request via Cadence Online Support, including the netlist, the Spectre log file, the behavioral model files, and any other information that can help identify the problem.
FATAL (CMI-2010): Assertion failed in file `waves.c' at line 12549.
FATAL (SPECTRE-21): Assertion failed.

It is related to the block "shifter_combiner" in the rfLib, and the simulation could run after I remove this block. But I have to use this block for simulation.

Any idea how to resolve this issue?

  • Hi GuanghuaShu,

    When spectre fails with "Assertion Error", something bad has happened and the simulator cannot recover. You need to contact Customer Support (support.cadence.com) and file a Case. Please include your testcase. I searched our records here, but found no similar issues with the shifter_combiner.

    best regards,
    Tawna
