How to know if a terminal pin is in the left,right,top and bottom of a circuit symbol?

Reinice

Hi All,

How can I know if a terminal pin is in the left,right,top and bottom of a circuit symbol? and how to count them?

ex.

left - 13 terminal pin

right - 10 terminal pin

top - 2 terminal pin

bottom - 0 terminal pin

Thank you very much in advance.

Best Regards,

Reinice

  • Reinice,

    Here's a function I've used to categorize the side a pin is on (based on the xy (e.g. centerBox) of the pin):

        /***************************************************************
    *                                                              *
    *                  (abGetClosestEdge xy bBox)                  *
    *                                                              *
    *  INTERNAL function to return one of the symbols left, right  *
    *   bottom or top to indicate whether the specified point is   *
    *  closest to which edge - given a bBox of the symbol - prior  *
    *  to adding pins or labels. Helpful to determine orientation  *
    *                       of labels, etc.                        *
    *                                                              *
    ***************************************************************/
    (defun abGetClosestEdge (xy bBox)
      (let (edgeData distances)
        (setq edgeData
              (list
                (list (xCoord (lowerLeft bBox)) (xCoord xy) 'left)
                (list (yCoord (lowerLeft bBox)) (yCoord xy) 'bottom)
                (list (xCoord (upperRight bBox)) (xCoord xy) 'right)
                (list (yCoord (upperRight bBox)) (xCoord xy) 'top)
                ))
        (setq distances 
              (foreach mapcar edge edgeData
                       (list (abs (difference (car edge) (cadr edge)))
                             (caddr edge))))
        (cadar (sortcar distances 'lessp))
        )
      )
     
    Maybe that will get you started?
