Abutment of one object with itself. How?

Zelli

I do not have left and right objects. (leftdiff, rightdiff). I have one diffusion object. Thus, I cannot use this standart:

"procedure(tranAbutFunction(instA instB pinA pinB pinAside conn event @optional group)

let(( result pinAcontP pinAstrP pinBcontP pinBstrP pinAw pinBw pinAcontV

pinAstrV pinBcontV pinBstrV drop_moving debugging eqW )"

And how I may use abutment in my case ?

  • Thanks, but... I will explain:

    Аssume there is such transistor (I will try to represent top view):

    bgss
    bgds
    bgss

    b - substrate
    g - gate
    s - source
    d - drain

    I want that abutment worked like this:

    bgss     ssgb     bgsssgb
    bgds +  sdgb =  bgdsdgb
    bgss     ssgb     bgsssgb


    And I write:

      when(diff~>dbId != nil objId = diff~>dbId
               when(objId~>pin != nil objId~>pin~>name = "source")
               dbReplaceProp(objId "vxlInstSpacingDir" "list" list("right"))
               dbReplaceProp(objId "vxlInstSpacingRule" "float" msdd)
               dbReplaceProp(objId "abutAccessDir" "list" list("right"))
               dbReplaceProp(objId "abutFunction" "string" "tranAbutFunction")
               dbReplaceProp(objId "w" "float" W)
               ;dbReplaceProp(objId "contactParam" "string" "leftcnt")
              )

    Result:

    >>> spcMosAbutFunction
    instA~>name = "|MA1"
    instB~>name = "|MA4"
    pinA~>pin~>name = "source"
    pinB~>pin~>name = "source"
    pinAside = 8
    conn = 1
    event = 2
    group = db:239227436
    *Error* get/getq: second arg must be a symbol or a string – nil

    >>> spcMosAbutFunction
    instA~>name = "|MA1"
    instB~>name = "|MA4"
    pinA~>pin~>name = nil
    pinB~>pin~>name = nil
    pinAside = 0
    conn = 0
    event = 3
    group = db:239227436
    Calculating un-abutment
    Returning result t

    :(((((

    But in standart example it is written:

      when(leftdiff~>dbId != nil objId = leftdiff~>dbId
               when(objId~>pin != nil objId~>pin~>name = "source")
               dbReplaceProp(objId "vxlInstSpacingDir" "list" list("left"))
               dbReplaceProp(objId "vxlInstSpacingRule" "float" msdd)
               dbReplaceProp(objId "abutAccessDir" "list" list("left"))
               ;dbReplaceProp(objId "abutClass" "string" cellViewId~>cellName)
               dbReplaceProp(objId "abutFunction" "string" "tranAbutFunction")
               dbReplaceProp(objId "w" "float" W)
               dbReplaceProp(objId "contactParam" "string" "leftcnt")
              )

      when(rightdiff~>dbId != nil objId = rightdiff~>dbId
               when(objId~>pin != nil objId~>pin~>name = "drain")
               dbReplaceProp(objId "vxlInstSpacingDir" "list" list("right"))
               dbReplaceProp(objId "vxlInstSpacingRule" "float" msdd)
               dbReplaceProp(objId "abutAccessDir" "list" list("right"))
               ;dbReplaceProp(objId "abutClass" "string" cellViewId~>cellName)
               dbReplaceProp(objId "abutFunction" "string" "tranAbutFunction")
               dbReplaceProp(objId "w" "float" W)
               dbReplaceProp(objId "contactParam" "string" "rightcnt")
              )

    and abutment work in this case:

    sgd     sgd    sg*gd
    sgd +  sgd = sg*gd

    and in this:

    sgd     dgs    sgdgs
    sgd +  dgs = sgdgs


    Why does not work  my variant ?
