APS-PSS error: "ERROR: ZERO DIAG reordering in Matrix factor"

Aldo2

Hello!

How can I avoid the following error running an aps-pss with mmsim 10.1?

Error found by spectre during periodic steady state analysis `pss'.
    ERROR: ZERO DIAG reordering in Matrix factor
    ERROR: ZERO DIAG reordering in Matrix factor
    ERROR: ZERO DIAG reordering in Matrix factor
    ERROR: ZERO DIAG reordering in Matrix factor
    ERROR: ZERO DIAG reordering in Matrix factor

...

Thank you

  • Aldo,

    I would suggest you log a service request for this issue. It looks like CCR 941065 which is to do with the beat frequency calculated by the GUI not matching the actual beat frequency due to rounding error and thus getting an inaccurate match (probably looking at the analysis statements in the input.scs would reveal this). You could try typing "autofund=yes" into the Additional Parameters field at the bottom of the PSS options form - but this is very much a wild guess - it may not be this problem at all. Without seeing the data, it's very hard to be sure (there are very few reports of this precise error message).

    So that's why a service request makes sense - we can then take a more detailed look at the data.

    Regards,

    Andrew.
