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?

  • Mark,

    There is ABSOLUTELY NO REASON why you should not be able to make it work for both scenarios. Once you've decided whether the user will be setting the dimensions  in metres or microns on the component, you can make it consistent everywhere.It would be very odd if you specified the dimensions differently when placing an instance on the schematic from placing an instance on the layout.

    This is not complicated - so I'm slightly mystified as to why it is seen as being complicated.
