    tsmc13rf pdk file in cadence virtuoso

    i am using the tsmc13rf pdk in cadence virtuoso

    there is a lot of nmos types that i dont know what is the difference between them

    nmos1v
    nmos2v
    nmos3v
    nmos1vcap
    nmos1vhvt
    nmos1vlvt
    nmos1vn

    would anyone help me to identify the difference between this instances?

    nmos1v
    This is the 1V device (gate/drain breakdown).

    nmos2v
    This is the 2V device (drain breakdown, need to verify if gate breakdown is 2V, sometimes it is not)

    nmos3v
    This is the 3V device (drain breakdown, need to verify if gate breakdown is 3V, sometimes it is not)

    nmos1vcap
    Nmos capacitor? Seems like it might be a moscap.
    nmos1vhvt
    1V device with threshold implant for high threshold voltage (reduces leakage).

    nmos1vlvt
    1V device, with threshold adjustment for a low threshold voltage (more leakage, but better headroom).

    nmos1vn
    Not sure about this one.
