Standard Cell Design Project – SKY130

📌 Project Overview

This repository documents my ongoing work on CMOS standard cell design using the SKY130 (130nm) PDK.
The objective of this project is to understand and implement the complete standard cell design flow from schematic to layout-level verification.
