Check LVS for Pcell

NguyenDinh

Hi all, I am a newer in Pcell. I designed a Pcell and run LVS, and had errors. I show  it below. Can anyone help me? Thank!

    I don't know where you are seeing these errors - without knowing that it's hard to know.

    However, it sounds as if you're loading the code containing pcDefinePCell in (say) the libInit.il of the library; that makes no sense, as you wouldn't redefine the PCell every time the library is opened - once you define it, the code is stored within the view and there's no need to keep redefining it (and you'll hit issues like this).

    Maybe you're also calling leDefineMPPTemplate() too in the libInit.il - that is not available in all interfaces (like the stream interfaces) - you could instead add:

    when(isCallable('leDefineMPPTemplate)
      leDefineMPPTemplate(...) ; or load the code containing this call
    )

    As I said, without knowing what files you have, what's defined where, and what is producing these errors, I can't really be more specific - this is all based on supposition and guesswork.

    Regards,

    Andrew
