DRD error message meaning

Hi,

I am trying to make the gnd rails at the bottom of the PR boundary, When I was trying to make a metal 1 line for the gnd rail, the DRD tool points out 2 messages: "minPRBoundaryInteriorHalo 0" and "Off-Screen minPRBoundaryInteriorHalo 0" (please see the image below). After I make this rail, there is a permanent error highlighted (last image). I don't understand these terms. Please help what I am doing wrong here?

Thanks and regards,

Vishesh

This is covered in the documentation. In the search box at the top of the help menu in Virtuoso enter "minPRBoundaryInteriorHalo" and in the documentation system you should see several results. I'd look a the "DRD Editing and PR Boundary Objects" which describes this fairly well.

Also, some coverage in this article: How to create a blockage region around the inside of the boundary, to prevent DRCs due to fill insertion, for example.
