geClosePolygon() does not work correctly

sparksu

I encountered a problem while using utility function "geClosePolygon()".

It is documented in "skdfref.pdf" :

**********************************************

         geClosePolygon(

                    d_cellViewId

                    l_points

                    t_snapMode

          ) =>  t/nil

*********************************************

But my codes did not work as it was described in file "skdfref.pdf".

geClosePolygon(deGetCellView() list(0:0 10:0 10:10) nil) => argument #3 should be a string.

geClosePolygon(deGetCellView() list(0:0 10:0 10:10) "orthogonal") => ((10.0 10.0) (0.0 10.0) (0.0 0.0)) 

geClosePolygon returns a list instead of t/nil.

 

My software version is 5.10.41.500.598.

And my document title is:

    Cadence Design Framework II SKILL Function Reference

    product version 6.31

    July 2007

  • You should contact Cadence Customer Support to report bugs - that is the correct avenue for getting things fixed.

    As far as I can tell, the documentation is wrong - it should say that the third argument needs to be the snap mode (e.g. "anyAngle", "diagonal" etc) and not nil as in the example. The return value should be the resulting list of points for the closed polygon - it doesn't actually create the shape.

    However, I don't think it actually works correctly from my experiments - it does not appear to be trying to ensure an orthogonal polygon, and when I used anyAngle with certain point lists, I end up with a list of two points, which is clearly incorrect.

    That said, I can't think of any case where I'd actually want to use this function!
