Is there a similar skill function (or other workaround) to "avExtractedCellViewCallProc" when generating a SPICE output? - during QRC extractions

frankp

Hello Cadence folk,

In ICADV12.30.ISR15, QRC tool

When generating layout extractions in SPICE output (not the usual "Extracted" view), is there a way to invoke a (skill or other) procedure at the end of the SPICE generation ?. 

I've noticed that when the output type is "Extracted", there is a "Call procedure" field that appears on the QRC form. However this field is absent when the output type is "Spice". I see per the help documentation, there is a skill function that exists named "avExtractedCellViewCallProc" which is invoked when an extraction of type "Extracted" is generated. I am unclear at the moment if this a user-trigger function that needs to be registered (similar to PVS triggers) or if it simply needs to defined by the user. However, it is clear per the name of the function that it will be invoked for extractions of type "Extracted" -not Spice.

Is there someway to call a procedure to execute actions for extractions of type "Spice" ? -  akin to a POST trigger. 

Thank you

Regards,

Frank

  • Hi Frank,

    I don't believe so. The avExtractedCellViewCallProc is invoked by the program that generates the extracted view, whereas the SPICE format is directly output by Quantus QRC - not sure there's really a place for a SKILL hook there (it's unclear why it would need SKILL to do any processing anyway).

    If you need something like this, I'd suggest you contact customer support to outline  your requirement.

    Regards,

    Andrew.

    Hello Andrew,

    The reason why this "hook" is needed is because the SPICE output file ends up in the user's workarea as a regular text file. It would have been useful and more manageable if a new view (of type text) was created, similar to when an extracted view is created. This way, a user will not inadvertently delete a needed SPICE file when he (or she) is removing file clutter in the extraction directory. I was hoping to have a call procedure that copies the SPICE text file into a newly created text view.

    Hi Frank,

    Understood - better still would be to have a view of type "Spice" as then it could be directly included in simulation (when using spectre). Anyway, if you want such a hook, customer support is the way to go as then we can file an enhancement change request on your behalf.

    Regards,

    Andrew.

    Hi Frank,

    A colleague pointed out to me that it's possible to add a post-processing script on the Netlisting tab on the QRC Quantus form. It's not SKILL, but a command that is invoked upon completion. More details can be found in this article. Thanks Viki for the suggestion!

    Regards,

    Andrew.

    Thanks Andrew for going the extra mile.

    The referenced article seems to be exactly what I was searching for (haven't tried out though yet).

    Regards,

    Frank
