I am trying to use Calibre DFM commands to evaluate the amount of critical area in my layout designs for instance for shorts.
I have created a new layout rule for shorts and tried to see the results of the check.
However, I am only obtaining a single error result, that is the whole layout polygon. What I mean is that the error does not point the location of the critical areas, but the whole layout.
When I define a small radius for the defects, no result is shown, and when I reach a given threshold radius from which a critical area is detected, then the whole layout is highlighted.
And the whole layout area is not critical... I promess! XD
My objective is to calculate the amount of critical area in my layout, for instance 1 square um, and if possible to highliht it in the layout.
Is this possible? Can someone give me some advice?
