Spectre error when simulating with extracted view

Pyroblast

Hi,

As the topic says, when I do a simulation with the extracted view I get this error:


ERROR (SFE-400): multiple case sensitive symbols have been created which match the case insensitive symbol `C2'.

Does anyone know what this means? How can I solve this?

This C2 is a MOM CAP ASY MM.

From what I can understand there might be an issue with this cap, but don't know what and why. Doesn't make any sense.


Regards.

  • I'm not sure what would cause this in a Cadence extracted view flow. My guess is that maybe you are using extracted views from a tool other than QRC? Or maybe including a SPICE or DSPF definition of the extracted layout.

    If something is defined in SPICE or included as a case-insensitive netlist, then maybe it could clash with another instance which is case sensitive. I tried a simple case and couldn't reproduce it and could find no record of this error message anywhere.

    So I'd like to understand how the data was produced, and ideally to see the netlist that is giving the error. Can you log a support request with customer support so that you can share the netlist (if you can't share it here), and then post the case number so I can take a look?

    Thanks,

    Andrew.
