Automatically placement of PINS on NETS

DannyRitt

Hello,


When generating/updating PINS in VXL it typically places them near the 0,0 coordinates as one group. I have a large block with many PINS, all grouped near 0,0 coordinates. I am interested to automatically place them on objects with the same layer and NET name. These PINS do not need to be on EDGES but on polygons with the same NET name. The skill script will take all selected PINS and move them to the matched path/rectangle/polygon with the same NET name.

Any ideas will be greatly appreciated.

Danny

    Hi Dan,

    Can you please help me to move the pin on the net  if pin name and net name is same using skill?

    Try the next code:

    procedure(MovePinsToInstances()
    let( (term pin net childTerm pinFigLocation location instTerm pinFig)
    cv=geGetWindowCellView()
    foreach(term cv~>terminals
    ; iterate over all the pins for this terminal
    foreach(pin term~>pins
    pinFig=pin~>fig
    net=term~>net
    ; only do this if there aren't more than one inst term
    ;unless(cdr(net~>instTerms)
    instTerm=car(net~>instTerms)
    childTerm=instTerm~>term
    childPinFig=car(instTerm~>term~>pins)~>fig
    ; location within the instance master
    location=centerBox(childPinFig~>bBox)
    ; transform to the top level coordinate system
    location=dbTransformPoint(location instTerm~>inst~>transform)
    pinFigLocation=centerBox(pinFig~>bBox)
    ; calculate the overall transform to move the pin to the new location
    ;transform=dbConcatTransform(list(-xCoord(pinFigLocation):-yCoord(pinFigLocation) "R0" 1) location)
    transform=dbConcatTransform(list(-xCoord(pinFigLocation):-yCoord(pinFigLocation) "R0" 1) list(xCoord(location):yCoord(location) "R0" 1))
    dbMoveFig(pinFig cv transform)
    ;    )
       )
      )
     ) ; let
    )
