    About can't find PDK in layout in Cadence

    I have a VCVS instance in my schematic design. I can't find VCVS in layout after generate from schematic because there is no VCVS PDK in Layout. How can solve this problem? Thanks. Attached is VCVS symbol in schematic.

    PDKs pertain to physical implementation at a foundry (and
    the precursor steps of design capture / synthesis / analysis).

    vcvs is an ideal component with no physical implementation.
    It is ignored for LVS (lvsIgnore='t') and there is nothing to be
    generated.

    Now if you made a transistors-and-passives implementation
    of that function (like, say, an op amp buffer with the same gain)
    using foundry PDK library elements then you would see a
    schematic-driven-layout produced.
    .

    Hi, thank you for your response. It do solve my problem. I have one more question. How can I generate schematic - driven-layout in virtuoso?
