Hey Guys, I had a quick question. I have created an n-trasistor array and now i want to draw an n well over it and change it to a p-transistor array. However, Since i have used subcells while building the array the diffusions don’t flip once i draw the nwell. Is there anyway i can merge all the subcells into a single flat layer so i can draw the nwell without any drc’s in magic.

To change it to P type you have to change the nsdm to psdm also. But if you want to just "merge" multiple cells together, the KLayout should hande that just fine, use "Flatten Cell" to do it

Thanks @User will give this a shot

@User: You can edit any instance of the array and paint nwell to change the transistor type. Since every instance in the array uses the same base cell, then editing the cell definition will change every instance of it. I do not recommend flattening an array, as basically everything becomes inefficient when working on flattened layout.

Thank you @User will give that a shot as well
