Sky130 Opamp Practice

This repository contains practice materials for designing and simulating operational amplifiers (opamps) using the Skywater 130nm (Sky130) process with xschem and magic tools.

Getting Started

Topology

How to Use

1. Clone the repository
   First, clone the repository to your local machine:

   git clone https://github.com/gilangfajrul/sky130_gff_opamp-practice.git

2. Navigate to the xschem directory
   Change into the xschem/ directory:

   cd xschem/

3. Open the schematic
   Open the op_tb.sch schematic in xschem:

   xschem op_tb.sch

4. Edit the symbols
   Click on the symbol you want to edit, then press e to open the symbol editor.

5. Create the layout
   Layout your schematic using magic tools in the mag/ directory:

   magic -d XR

Additional Tools

There are additional scripts and tools that can help with transistor analysis and netlisting:

1. Copy the transistor_modes.py script
   Copy the transistor_modes.py file into your netlist directory (usually located at ~/.xschem/simulations/).

2. Run the script
   Use Python to run the script with your .lis file:

   python3 transistor_modes.py op5_tb.lis
