How to dump DRC shape coordinates into a file?

LostInRTN

I need to get the coordinates of the polygons, rectangles, etc that are highlighted after a DRC run in the Error Layer Window. Equivalently these are the shapes the errorLayer procedure uses. I've tried geGetSelSet, the marker functions and the Hilight functions and none of these seem to be the method the ELW uses to show the DRC errors.

 Thanks

    You can use ?saveTextErrors function in avParameters. In the drc form, click on "avParameters" button, locate the ?saveTextErrors function and enter a suitable filename. The coordinates of all the error shapes will be dumped to a text file similar to:

    test_error 2000.000000
    Rule      2 : Testing
    1 1 1 Fri Nov  6 08:49:32 2009
    Testing
    e 1 2
    CN test_error C 1 0 0 1 0 0
    -590 12050 -590 5440
    -370 5440 -370 12050

    To get the actual coordinates, divide the numbers by the dbuPerUU used. For the above example, it is 2000. The above example shows the 4 corner coordinates of an error rectangle in database units. An example of calculating the coordinates would be:

    X1 = -590/2000 =-0.295
    Y1 = 12050/2000 = 6.025

    Hope that this helps you. : )  For your information, you can also use ?outErrorLayers to dump all the error shapes into a gds file.
