Insert cell only with layout no symbol view to schematic view.

    > It takes advantage of using a metal resistor in your PDK (most PDKs have something similar)

My PDK only provides small metal resistor's layout view. Is it possible to use layout only cell to the schematic? 

View symbolic
----
... (omitted)
access drwxr-x--- [r]
files layout.oa
master.tag
managed by N/A (data not currently managed)

BTW:

There is normal metal resistor with symbol and layout view, but the PDK code limits the minimum size/width of the resistor.

Is there a way to bypass the PDK limits as a workaround?

 

  • It rather depends on what the LVS rules do with such a component. If they are just treated as a short in LVS, then there will be nothing in the extracted representation for you to probe. If they are preserved in the extraction part of the LVS, then they might still exist in the extracted representation and you can probe the terminals that way. It's hard to know without seeing the details of how it behaves... which is hard to know without any details of the PDK you're using. I'd expect the PDK would need to support matching a component on the schematic side with that on the layout side - even if this was being used as a means of breaking a net rather than a true metal resistor - so you might need to talk to your PDK provider.
