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,

    Without seeing your pcell, who knows what the problem is. Most likely there is a difference between what the pcell is expecting and what the CDF value is - either in the type of the value it sees, or in the value. Maybe the pcell is expecting the value to be in microns?

    Above you seem to be setting the default value in the first case to 0.2 nm (which is a bit small and rather ahead of state of the art technology).
