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!

    Hi Andrew,

    I have another issue, when I run LVS. I have some errors, below:

    ".......

    LVS completed. NOT COMPARED. See report file: example.lvs.report

    LVS completed. CPU TIME = 0 REAL TIME = 0 LVHEAP = 67/91/91 MALLOC = 59/59/59 ELAPSED TIME = 0

    ERROR: Corresponding cells could not be identified.


    ERROR: Nothing in layout.


    *** Calibre finished with Exit Code: 4 *** "

    I have researched in cadence forums and I know that I have not created any pin. So, I use a function to create pins, I show below:

    minus = rodCreatePath(
    ?layer "M1"
    ?cvId pcCellView
    ?width w
    ?pts list(caar(contactLeft~>dbId~>bBox):
    (abs(abs(cadadr(contactLeft~>dbId~>bBox))- abs(cadar(contactLeft~>dbId~>bBox)))/2 + cadar(contactLeft~>dbId~>bBox))
    caadr(contactLeft~>dbId~>bBox):
    (abs(abs(cadadr(contactLeft~>dbId~>bBox))- abs(cadar(contactLeft~>dbId~>bBox)))/2 + cadar(contactLeft~>dbId~>bBox)))
    ?pin t
    ?pinLabel t
    ?pinLabelLayer list("M1" "pin")
    ?pinLabelHeight 0.5
    ?termName "MINUS"
    ?termIOType "inputOutput"
    )

    But  the result is not changed. I do not why. May I wrong, am I ?. Would you help me ?
    Thankyou
