Min space well same potential

Technologies often allow smaller minimum space between wells on same potential than on different potential.
Often this is translated to a rule that allows smaller minimum space for well on the same net.
Is this supported by KLayout DRC ?
I only see DRC::Netter used for antenna checks.


  • If they are truly so closely spaced that they would flag the generic rule (which I know can be absurdly large - I've seen 50um on a 180nm process) and truly at same potential, why not just bridge the gap with more NWell and make it all one piece?

  • It could also be a notch in the NWell around part of a n-type device.

  • @fatsie Apart from the notch solution, there is no "drc connected" currently. It's on my todo list, but it's not going to come quickly.
