QRC: extract only down to a certain layout level

Hi everybdoy,

is it possible to extract the parasitics of a layout only for some parts of the hierarchy?

E.g. I would like to extract the parasitics of the "top level" and the level below to see the parasitics of certain (very long) wires. Further I would like to use the extracted view to include these parasitics into a simulation. The "sub cells" sould be included as normal schematics in the simulation.

I tried with the HRX, but with my settings this generates the sub blocks as extracted views in an additional library...

 Thank you very much!

 Best regards,

Markus

    Hello Andrew,

    thank you for the hint :-)
    Grey/black boxing is not doing the things I want, but based on this keywords I've found the correct option: "extraction_setup -ignore_cells_file xyz".

    Best regards,
    Markus
