README
# Simulate a Skywater 130nm standard cell using ngspice
This repository is a template for project 1.1 that takes you through:
* Browse the standard cells
* Choose a standard cell to simulate
* Copy the spice file
* Modify the Makefile
* Modify the spice file to provide inputs to the gate
* Run the spice simulation to get a plot of the inputs and outputs
* Measure propagation delay
