ERROR (USIMUWI-20008)

huadel

Hello,

I am simulating a DC/DC Converter feedback loop. I have this error, that appears amid transient simulation in ADE:

Internal error found in spectre at time = 1.36483 ms 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: Internal error with exception. Terminating simulation.
Error found by spectre at time = 1.36483 ms during transient analysis `tran'.
    ERROR (USIMUWI-20008): The simulator failed to flush the stream for the format 'psfxl'. Check the format and supporting functions (for user defined formats) before running the simulation again.no error
Internal error found in spectre at time = 1.36483 ms 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 (SPECTRE-21): Assertion failed.

Is it related to a setup or licensing issue? ( I simulated this loop before without error using the same setup )

Thanks.

    You should do what the message suggests and contact customer support. It's possible that this is because either the disk filled up or you exceeded your quota, but the couple of previous reports of this message suggests that this may not be the case. It might be due to an excessive number of signals being saved (if this is post-layout for example), but this is really guesswork. No clear answer from either occurrence that's been reported; one we haven't got the testcase, and the other is not fully resolved yet.

    So that's why we'd need you to talk to customer support - so we can explore in more detail what's going on.

    Regards,

    Andrew
