poly path count()

poly_path_count()

Select polygons based upon path count information computed during a merge operation. Input layer must be the result of a merge command. Returns: A polygon layer.

Syntax

dve_drc (poly_path_count (inLayer) operator distance [, qualifierName, qualifierValue]);

where:

inLayer	A polygon layer produced by a merge operation between two layers
operator	< Less than <= Less than or equal to == Equal to > Greater than >= Greater than or equal to
value	A real value in layout units
qualifierName, qualifierValue	A name, value pair that qualifies the rule

Path Count Qualifier: DVE_RN_PATH_COUNT

Qualifier Resource Value:

DVE_RV_PATH_COUNT	(default) Select based upon path count of top polygon
DVE_RV_ANTI_PATH_COUNT	Select based upon path count of bottom polygon

Path Code Qualifiers

DVE_RN_PATH_CODE

Example 1

decl lyrCond = dve_import_layer ("cond");
decl lyrCond2 = dve_import_layer ("cond2");
decl lyrError101 = dve_export_layer ("error101");
decl lyrPolyMerge = NULL;
decl lyrPoly = NULL;
lyrPolyMerge = dve_bool_not (lyrCond, lyrCond2);
lyrPoly = dve_drc (poly_path_count (lyrPolyMerge) >= 1,
        DVE_RN_PATH_CODE, DVE_RV_TOP,
        DVE_RN_PATH_CODE, DVE_RV_INT);
lyrError101 += dve_drc (all_edges (lyrPoly),
        "Metal layer outside and butting internally");
