Hi All,

I'm working on Cadence IC616 with UMC40LP technology & using Calibre for DRC. I've encountered following DRC error.

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...
