How to get " the rotation & coordinate to the top " of the cellname in a large layout design ?

Dear All,

I want to get  " the  rotation & coordinate to the top " of the cellname in a large layout design , but how to do it ?

The cellname maybe has more than one  and the layout design is very large .

Thank you,

Charley

    Charley,

    Is this the sort of thing that you want?

    procedure(CCFfindInstLocation(cvId @key libName cellName viewName 
        found (transform list(0:0 "R0" 1)))
      foreach(inst cvId~>instances
        if((!libName || libName==inst~>libName) &&
          (!cellName || cellName==inst~>cellName) &&
          (!viewName || viewName==inst~>viewName) then
          found=cons(list(dbTransformPoint(inst~>xy transform) 
            cadr(dbConcatTransform(inst~>transform transform))) found)
        else
          found=CCFfindInstLocation(inst~>master ?libName libName 
            ?cellName cellName ?viewName viewName ?found found 
            ?transform dbConcatTransform(inst~>transform transform))
        )
      )
      found
    )

    Then you can just call:

    CCFfindInstLocation(geGetEditCellView() ?cellName "adc_sample_hold")

    and it returns a list of top level coordinates and overall orientations (one per "flattened" instance):

    (((1559.77 15.4) "R90")
    ((1786.765 130.68) "R90")
    )

    Note there is no attempt to deal with mosaics in this code - I was just keeping it simple.

    Regards,

    Andrew
