quotation mark replacement with pcreReplace?

oyayla

Hi,

I am trying to get outputs from ocean using  outputs() function into a list from a post layout simulation(netlist is dspf file). The format of outputs() is sth like this: /VCO/VCO_CORE/CAPBANK[0]/MMN0:G

To be able to plot these with ocean, I need to convert them to below format:

v("VCO.VCO_CORE\\/CAPBANK\\[0\\]\\/MMN0\\:G)

In other words, I need to use double escape character before "/ [ ] : " characters. We can assume VCO section is common for all saved nets so /VCO/ => VCO. is not much an issue. Also I was able to change [ ] : and / with pcreCompile and pcreReplace but I couldn't figure out how to add quotation mark after v(

To add double backslach before : [ ]/ , I have below

comPat2 = pcreCompile("[:/\\[\\]]")

pcreReplace(comPat1 "/VCO/VCO_CORE/CAPBANK[0]/MMN0:G" "\\\\&" 0)

The question is how I can replace quotation mark in pcreReplace such that /VCO/ becomes v("VCO?

Thanks

    I am putting the sample of code I am trying to fix. As mentioned earlier, this script is supposed to get saved nets from outputs() function, post-process with pcre and plot it.

        sigList_raw = outputs()

        ; Compile patterns
        comPatSpecial = pcreCompile("[:/\\[\\]]")
        comPatTop = pcreCompile("/VCO/(.*)")

        sigList = list(nil)
       
        foreach(sg sigList_raw
            pcreExecute(comPatTop sg)
            sigNet = pcreSubstitute("v(\\\"VCO\\.\\1\\\")")

            ;Add escapes for special characters
            sigNet = pcreReplace(comPatSpecial sigNet "\\\\&" 0)

           plot(sigNet)

        ); foreach sigList

    Example input: /VCO/VCO_CORE/CAPBANK[0]/MMN0:G

    Expected output: v("VCO.VCO_CORE\\/CAPBANK\\[0\\]\\/MMN0\\:G")

    and plot the waveform.

    Current issue with this script is that final signal names are strings as below and when I use evalstring, it gives below error message:

    "v(\"VCO.VCO_CORE\\/CAPBANK\\[0\\]\\/MMN0\\:G\")"

    Error message:

    *Error* evalstring: argument #1 should be a string (type template = "ts")

    Thanks

    In theory you should just be able to use the name from outputs() directly, but I think in this case the name is confusing the mapping code. So I suggest that instead you do:

    sigList=outputs(?map nil)
    foreach(sg sigList
      plot(v(sg))
    )

    This will be much simpler - you're over-complicating the problem. I wouldn't use evalstring anyway, I'd use a pattern substitution and then pass the result to the v() function; however, the approach of getting the unmapped names (with ?map nil) is even simpler and avoids having to do all the substitution.

    Regards,

    Andrew.

    Hi Andrew,


    Thanks for the reply. I have tried both plot(v(sg)) way and ?map nil way. Both of them are working as you mentioned.

    Thanks for the suggestions which saved me the above complications.

    Thanks,
