Getting coordinates for pin placement

LongTimeNovice

Hello, everyone.  I'm trying to examine a pin that's in a layout subcell, and then draw a pin directly over it.  I'm having trouble getting my coordinates in the correct format.  I'm sure of two things: 1) I'm probably making this harder than it needs to be, and 2) I'm probably missing something obvious.  I've pasted the code, and below that is the response from Cadence.

############# Here is my code #############

;GET bBox OF PIN IN TARGET INSTANCE

pBox=car(instTerm~>term~>pins)~>fig~>bBox

;SEPARATE OUT LOWER LEFT COORDINATES

pBoxLL=car(car(pBox))
pBoxFixLL=dbTransformPoint(pBoxLL inst~>transform)

;GET LOWER COORDINATE AND CONVERT TO STRING

pBoxFixLower=car(pBoxFixLL)
sprintf(pBoxFixLower "%L" pBoxFixLower)

;GET LEFT COORDINATE AND CONVERT TO STRING

pBoxFixLeft=cdr(pBoxFixLL)
sprintf(pBoxFixLeft "%L" pBoxFixLeft)
pBoxFixLeft = substring(pBoxFixLeft 2 strlen(pBoxFixLeft)-2)

;MAKE A STRING WITH LOWER AND THEN A COLON AND THEN LEFT

pinCoordsLL=strcat(pBoxFixLower ":" pBoxFixLeft)

;SEPARATE OUT UPPER RIGHT COORDINATES

pBoxUR= cdr(car(pBox))
pBoxUR=car(pBoxUR)
pBoxFixUR=dbTransformPoint(pBoxUR inst~>transform)

;GET UPPER COORDINATE AND CONVERT TO STRING

pBoxFixUpper=car(pBoxFixUR)
sprintf(pBoxFixUpper "%L" pBoxFixUpper)

;GET RIGHT COORDINATE AND CONVERT TO STRING

pBoxFixRight=cdr(pBoxFixUR)
sprintf(pBoxFixRight "%L" pBoxFixRight)
pBoxFixRight = substring(pBoxFixRight 2 strlen(pBoxFixRight)-2)

;MAKE A STRING WITH UPPER AND THEN A COLON AND THEN RIGHT

pinCoordsUR=strcat(pBoxFixUpper ":" pBoxFixRight)

;MAKE STRING WITH UPPER-LEFT COORDS AND LOWER-RIGHT COORDS SEPARATED BY A "/"

pinCoords=strcat(pinCoordsLL "/" pinCoordsUR)

;CONVERT THIS STRING TO A LIST CONTAINING L:L AND U:R

pinCoords = parseString(pinCoords "/")

;PRINT THESE VARIABLES FOR DEBUGGING PURPOSES

printf("  *** pinCoordsLL is %A\n" pinCoordsLL)
printf("  *** PinCoordsUR is %A\n" pinCoordsUR)
printf("  *** PinCoords is %A\n" pinCoords)

;MAKE A PIN USING pinCoords VARIABLE

leCreatePin( cv  pLPP  "rectangle"  pinCoords  pName  "inputOutput"  list("left" "right" "top" "bottom") )

############# This is the response from Cadence starting with the debugging lines and ending with the error #############

*** pinCoordsLL is "11.175:10.315"

*** PinCoordsUR is "11.605:10.745"

*** PinCoords is ("11.175:10.315" "11.605:10.745")

*Error* length: argument must be a list or an array - "11.175:10.315"

<<< Stack Trace >>>

leCreatePin(cv pLPP "rectangle" pinCoords pName ... )

I notice that the PinCoords list, when printed, looks right but has quotes in it.  I wonder if this throwing off my leCreatePin statement.

I'd love to hear your thoughts.

Thank you!

Steven.

  • Hi, Andrew.

    Thanks for responding.  It's always great to hear from you.

    First off, I'm so sorry I misrepresented the tool name.  You're exactly right: the tool is Virtuoso.  I didn't mean to imply that Cadence the company had anything to do with this.  I'm sure Customer Support would have been very helpful.  You all always do a great job!

    Please see my reply to Lawrence for my explanation of why I converted the coordinates to strings.  I know it was incorrect and certainly not what a professional SKILL programmer would do.  My education and work experience is in electrical engineering and layout, not programming, and I'm doing my best to create good scripts without bothering you all any more than necessary.  I'm able to figure out most things on my own through the Cadence Help documents and old posts on this forum, but sometimes I get stuck, and sometimes I go down the wrong path.  Thank you for setting me straight when I need it!

    Thanks again.

    Steven.
