Net list creation error

wgtkan

Hello,

An old solution has been posted to running into an error when simulating a schematic created in IC6.1 using specter simulator. 

When I added IC6.1 library (I'm using virtuoso 6.17 version) and other directories and ran the spectre simulation, I got Netlist Error:  

Could not find netlist procedure:ABbnNetlistProc instance "M1" in cell-view "Ch31_IC61" "Fig20_47" "schematic"

As a solution, this code was posted. Where should I place it?

defun(ABbnNetlistProc (inst)

    let((formatter netlister bulk sigs)

        ;----------------------------------------------------------------

        ; Get hold of the formatter and netlister objects

        ;----------------------------------------------------------------

        formatter=nlGetFormatter(inst)

        netlister=nlGetNetlister(formatter)

        nlPrintInstComments(formatter inst)

        nlPrintIndentString(netlister)

        nlPrintInstName(formatter inst)

        ;----------------------------------------------------------------

        ; Print the standard signals. Can't use nlPrintInstSignals

        ; because the parentheses would be around the terminals in

        ; the termOrder, and not include the bulk node

        ;----------------------------------------------------------------

        sigs=nlGetSignalList(inst)

        nlPrintString(netlister " (" car(sigs))

        foreach(sig cdr(sigs)

            nlPrintString(netlister " " sig)

        ) ; foreach

        ;----------------------------------------------------------------

        ; Get the bn parameter and output that as the connection, if

        ; it is set

        ;----------------------------------------------------------------

        bulk=nlGetParamStringValue(inst "bn")

        when(member(bulk '("D" "G" "S"))

            bulk=nlGetTerminalSignalName(inst bulk)

            )

        when(bulk

            nlPrintString(netlister " " bulk)

            )

        ;----------------------------------------------------------------

        ; Write out the close parenthesis, now that the bulk is written

        ;----------------------------------------------------------------

        nlPrintString(netlister ")")

        nlPrintModelName(formatter inst)

        nlPrintInstParameters(formatter inst)

        )

    I guess the post you're referring to is this one (always useful to have a cross-reference). 

    What I'd do is look at the M1 transistor in Ch31_IC61/Fig20_47/schematic and see what library it's from. Then add the function above into the libInit.il file within that library (or if one doesn't exist, create that file and put this code within it). You'll have to restart virtuoso for it to have an effect though.

    Alternatively, put it in your .cdsinit file.

    Regards,

    Andrew.

    Hello Andrew,

    Thanks for your prompt response. The library is from NCSU analog parts. I created libInit.il and put the above code into it and in my .cdsinit , I placed a line: 

    load(strcat("path to libInit.il"))

    Still, it is not working.

    You've clearly got some mangled characters in the code that you're loading (I would have thought that's rather obvious from the error message). By dumping the same sequence of characters to a file, I can see the same problem. Here's what it looks like in an editor such as "vi" when I do that:

    I see the same thing if I just cat the file too (that may depend on your terminal though).

    So, you appear to have some strange characters instead of whitespace at the beginnings of your lines (at least this line) in the code. You'll need to fix that.

    Regards,

    Andrew.
