The way how change the 'Display' in object properties of pin in symbol,

shane park

Hello, 

I am beginner at the skill language, and I am making the script which generate symbol and schematic automatically in Skill.

anyway, when I made symbol, by the below code 

  schCreatePin(cvSchem OpinId port "output" nil x_o:y_o+dy "R90")

however,

 the pins I made dosen't have 'Display' option in its Object property.

So, I also want to change this 'display property' into 'value' by code.

I found lots of website, but I couldn't figure out it.

I tried like below code, but it doesn't work.

foreach(term cvId~>terminals

  term->textDisplays="value"

)

Would you resolve this problem?

thank you.

  • Hi,

    I tried creating using the following code (from schCreatePin documentation):

    inputCVId = dbOpenCellViewByType( "basic" "ipin" "symbol" "" 'r )
    pinId = schCreatePin( (geGetEditCellView) inputCVId "I1" "input" nil 0:0 "R0" )

    It created a pin with its label displayed

    However you might have a different setup (or instantiate a different kind of pin?)
    I hope the following functions might help you:


    (defun get_schematic_pins (@optional (sch_cv (geGetEditCellView)))
      "Return pins from SCH_CV"
      (setof inst sch_cv->instances inst->pin))

    (defun get_schematic_pin_name_display (pin)
      "Return PIN name associated text display"
      (car (exists obj pin->children (and obj->objType=="textDisplay" obj->text=="name"))))

    (defun display_schematic_pin_name (pin @optional (visible t))
      "Show or hide PIN name associated text display according to VISIBLE toggle"
      (let ((text_display (get_pin_name_display pin)))
        ;; Make sure text_display was well fetched
        (assert text_display "Unable to fetch %A name text display" pin)
        (schSetPropertyDisplay ?object text_display ?visibility (if visible 'value 'off))))

    You should be able to use them like this:

    ;; Display all pin names in current cellview
    (foreach pin (get_schematic_pins) (display_schematic_pin_name pin))
    ;; Display name of pin created before using schCreatePin
    (display_schematic_pin_name pinId)

    Hope this helps

    Hi Aurélien,

    Thank for reply, but What I wanted was putting label on not 'schematic pin' but 'symbolic pin'.

    So, I used schCreateSymbolPin rather than schCreatPin.

    If I use just 'schCreateSymbolPin' , then the label (the name of each pin) is not visible, so I want modify the 'Display' option in its Object Property from 'off' to 'value'.

    I also tried applying the 'schSetPropertyDisplay' but it dosen't wok, but of course, I might do wrong ..lol
