Hi, I am trying to finish fixing DRC errors on my top level sky130 layout w/ pre-check. The last two types reported by Magic are [ERROR] - Violation Message 'All nwells must contain metal-connected N+ taps (nwell.4)', [ERROR] - Violation Message 'P-diff distance to N-tap must be < 15.0um (LU.3)' . The challenge I am having is that the locations pointed to in the magic_drc_check.drc.report do not seem to correspond to X,Y (um) feature locations in layout. Any suggestions on this?

I believe the error coordinates are in the internal units, so you would do "xinternal" where x is x coordinate.

As a follow up.. The errors do not show up doing local magic DRC check w/ the volare sk130 magicrc setup, or with the efabless online pre-check. So seems to be a discrepancy w/ the local pre-check Magic DRC check setup.
