I've encountered following DRC error. Code: POLY1 must be covered by N+ or P+ implant layer Exclude AA_CELL_MARK, HR and MR layers I've turned ON the following switches Since it's a block level Design. DRC UNSELECT CHECK L2_DENSITY // AL_RDL density checking DRC UNSELECT CHECK POLY_DENSITY // PO1 density checking DRC UNSELECT CHECK DIFF_DENSITY // DIFFUSION density checking Follow the attachment for more details..... Please do let me know how to handle this DRC... Thanks in advance...

I would expect that Booleans enforce field poly to be shot with one of the two (N+ or P+) but maybe not. Extend the N+ or P+ to cover all poly (plus extension), is what the rule evidently demands.
