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, Lawrence.

    I've still got a problem.  I'm sure it's related to what I'm feeding into the dbTransformBBox statement.  My definition of instPinList is probably wrong.  Here is my code:

     

    instList=selectedSet() ;MULTIPLE INSTANCES ARE SELECTED WHEN SCRIPT IS RUN

    ;CYCLE THROUGH INSTANCES, FIND PINS OF EACH INSTANCE, AND THEN GET EACH PIN'S COORDS BEFORE MOVING TO THE NEXT INSTANCE

    foreach(inst instList

    instPinList = inst~>instTerms~>term~>pins

    foreach( instTerm instPinList

    pinFig = car(instTerm~>term~>pins)~>fig

    printf("  *** pinFig is %A\n" pinFig) ;PRINT LINE FOR DEBUGGING

    pinCoords = dbTransformBBox(pinFig~>bBox inst~>transform)

    printf("  *** pinCoords is %A\n" pinCords) ;PRINT LINE FOR DEBUGGING

    );foreach

    );foreach

    And here is the response from Virtuoso:

      *** pinFig is (db:0x43911dcd) *Error* dbTransformBBox: Invalid bBox - (((5.82 5.88) (6.25 6.31))) <<< Stack Trace >>> dbTransformBBox((pinFig~>bBox) (inst~>transform))

    I'd love to hear your thoughts.  Thank you!
