layoutXL Gen from source doesn't give correct sizes.

MarkTown

 If I place my Pcell by hand the cell works fine. Sizes are what I expect them to be.

Gen from source gives me small values that can't be laid out.

The symbol though has "90n M" which doesn't match other tech files I've worked with "90n"

 I've tried two different ways of doing the CDF:

    cdfCreateParam( cdfId
        ?name           "w"
        ?prompt         "width"
        ?defValue       "0.2n"
        ?parseAsNumber  "yes"
        ?type           "string"
        ?units          "lengthMetric"
    )
 

 

I've also tried the following default value:

minMosWidth = 0.2 * 1e-6

?defValue       sprintf(nil "%g" minMosWidth)
 

Neither gives me the desired result.  Any thoughts?

  •  Yes, Andrew, I'm aware that its a units issue. I've tried quite a few different units trying to get them to match. I get the code working one way and then it breaks another way. 

     

    For something as easy to mess up as this, it would be nice if CD not only had an example like the 90nm sample code but also an explanation of why each cb, cdf, il and symbol has to be what it is and why. Where the conversion should be etc. I've thought I had ever line matched up with the CDS examples and yet it still didn't work. 

     

    So now its just going to ahve to be skill code that is placed. Its easy to make that work.  No gen from source in this version.

     

    thanks for you help
