While running DRC in sky130, I am getting a error for my model. Although it passes, it shows a soft error! Any suggestions?
```Loading DRC CIF style.

<@U073HK94F7W> Looks like `66/44` is the pwell drawing layer. This layer is not used in the magic tech file, so that’s what’s causing the warning, I think.

Thats a lot David and Sudhanshu! Now I remember that is has been discussed. Actually I think adding a pwell when doing nfet is not necessary . Thanks a lot for the suggestion and delay in replying!

What is Linen?
