Skill Pcell Post Trigger with doneProc

NC202503102342 23 days ago

Hi,

I read the post Skill Pcell Post Trigger Function - Custom IC SKILL - Cadence Technology Forums - Cadence Community but I couldn't find a lot of documentation on how to use doneProc.

I'm trying to access the bBox coordinates of the PCell and show the lower left point as a CDF parameter. My first approach was to use the following code

In the PCell code, I added the lines

cdfCreateParam( cdfId

?name "llCoord"

?type ""float

?prompt "PCell Lower left corner"

?editable "nil"

?callback "showLLCoord()"

)

cdfId->doneProc = "showLLCoord"

later, I have

procedure( showLLCoord()

let( ( bBox )

bBox = inst~>bBox
cdfgDat->llCoord~>value = listToVector( car( bBox ) )[0]

) ; let

) ; procedure

But it didn't work. How could it be done?

Thanks very much in advance.

correction:

cdfgData->llCoord~>value = listToVector( car( bBox ) )[0]

Without trying, I think you missed the following part of the citation:
CDF doneProc - it gets passed the instanceId that was changed

Your doneProc has no argument that would take the passed instanceId, though later you are trying to access the (then global) variable inst, which however will be prob. not defined. It might help to use:

procedure( showLLCoord(inst)

There are also mental shortcuts to access edges/corners of bBoxes, like leftEdge, rightEdge, lowerLeft, upperLeft, etc. that do what they are called, also see:

So you do not need to twiddle the bBox with vectors.
