 Spacing between nwell and deep nwell on the same net is set by the sum of the rules nwell.2 and nwell.5. By default, DRC run on a cell checks for the separate-net spacing, when nwell and deep nwell nets are separate within the cell hierarchy and are joined in the upper hierarchy. To allow net names to be joined and make the same-net rule applicable in this case, the ""joinNets"" switch should be turned on.
