A SKILL++ Pcell class object that is inherited from class pcParamClass.

Value Returned

t

If the database objects are created for a specified SKILL++ Pcell class.

nil

If the database objects are not created.

Examples

defmethod( pcDraw ((device RING))
    let((cv ringS ringW coreBBox llx lly urx ury pts ring)
     ringS = pcGetParamSlotValue(device 'ringS)
  ringW = pcGetParamSlotValue(device 'ringW)
   coreBBox = getCoreBBox(device)
   llx = xCoord( lowerLeft(coreBBox))
   lly = yCoord( lowerLeft(coreBBox))
   urx = xCoord( upperRight(coreBBox))
   ury = yCoord( upperRight(coreBBox))
    pts = list(
     llx-ringS:lly-ringS             ; points on inner edges
     urx+ringS:lly-ringS
     urx+ringS:ury+ringS
     llx-ringS:ury+ringS
     llx-ringS:lly-ringS-ringW   ; extending to outer edge
     llx-ringS-ringW:lly-ringS-ringW ; points on outer edges
     llx-ringS-ringW:ury+ringS+ringW
     urx+ringS+ringW:ury+ringS+ringW
     urx+ringS+ringW:lly-ringS-ringW
     llx-ringS:lly-ringS-ringW)
     ; layer is chosen for its color's visibility
     cv   = slotValue(device 'cvId)
     ring = dbCreatePolygon( cv list("Via2" "drawing") pts)
    callNextMethod()
  )
)
