[SOLVED] DRC error that I can't understand

[AMSA84]

Hi guys I have an error that I can't understand why is happening:



It is the first one. This kind of error has to do with the contacts to the NWELL. I had this error before, but not for this kind of layout (mosfet that will serve as power devices).

As you can see I have the contacts to the well but he still gives the error. The description on the right I never saw before.

Does anyone knows why this is happening?

If that's all one big NWell and only contacted about the
periphery, there may be regions where you violate the
tap-to-channel distance rules or something like that
because your device is too big without intervening taps.

I see. Thank you. You're right!
