PCells
=============================

Parametric Cells for the Generic PDK.

Consider them a foundation from which you can draw inspiration. Feel free to modify their cross-sections and layers to tailor a unique PDK suited for any foundry of your choice.

By doing so, you'll possess a versatile, retargetable PDK, empowering you to design your circuits with speed and flexibility.
