No matching .SUBCKT statement error in LVS check

archive
archive over 17 years ago

Hello All I am using Calibre-LVS for LVS check between final layout and verilog code both are generated by Cadence-Encounter v4.1. The output log file is enclosed. The LVS does not compare two files because of some errors like: Error: No matching ".SUBCKT" statement for "BFSVTX10" at line 43459 in file "/tmp/lvsRunDir/_decoder36.v.sp" Error: No matching ".SUBCKT" statement for "BFSVTX10" at line 43460 in file "/tmp/lvsRunDir/_decoder36.v.sp" BFSVTX10 is a standard lib given in STM cmos90nm lib. I appreciate your comment to solve this issue. Thanks, Ali

    Hello Kari,

    Thanks for your reply.
    There is a verilog translator integrated into the Calibre-LVS. I entered a verilog file (for netlist ) and a layout (a GDS file was imported to vituoso layout) as two inputs for the LVS. Hence I didn't use v2lvs. But if it is not a safe method please let me know the correct syntax.
    Also I didn't mention the std cells. I think this is the step I missed. How should I introduced them to the design? at starting point of the LVS check I see some warnings like this:

    "Warning: no module declaration for module CTBUFLVTX12_0 first encountered in module decoder36"

    CTBUFLVTX12_0 is std buffer from cmos90nm library.
    decoder36 is my top cell name.

    Thanks,
    Ali
