DRC error in TSMC65nm

[mursina]

These are some DRC error I am getting when I try to check DRC with IO pads, without IO pads these errors are not coming.
I kept p+ and n+ guardning also, but still these errors are not going, can someone please tell how to resolve this, thanks in advance 1.

Does your foundry groundrules package not include descriptions and illustrations for every one of these? It's kind of expected.

Armed with that understanding and guided by the helpful marker polygons you have no doubt already measured the features involved, verified the validity of the violation and identified the cause, to correct.

So what's next?
