OpenFASoC: Fully Open-Source Autonomous SoC Synthesis using Customizable Cell-Based Synthesizable Analog Circuits

https://readthedocs.org/projects/openfasoc/badge/?version=latest

OpenFASOC is focused on open-source automated analog generation from user specification to GDSII with fully open-sourced tools. This project is led by a team of researchers at the University of Michigan and is inspired by FASoC, that sits on proprietary tools. (See more about FaSoC at website)

Getting Started

Install all the prerequisites using the dependencies.sh script provided in the home location of this project (where this README.rst file is found). Supports CentOS7, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.

$ sudo ./dependencies.sh

For more info on getting-started, please refer to ["Getting Started" section ](https://openfasoc.readthedocs.io/en/latest/getting-started.html)

Below are the tool requirements along with their currently support versions that are updated regularly upon testing againsts the generators.

  1. Magic (version:8.3.453)

  2. Netgen (version:1.5.264)

  3. Klayout (version:0.28.12-1)

    • Please use this command to build preferably: ./build.sh -option '-j8' -noruby -without-qt-multimedia -without-qt-xml -without-qt-svg
  4. Yosys (version:0.36+8)

  5. OpenROAD (version:2.0_10905)

  6. Open_pdks (version:1.0.286)

  • open_pdks is required to run drc/lvs check and the simulations
  • After open_pdks is installed, please update the open_pdks key in common/platform_config.json with the installed path, down to the sky130A folder
  1. Xyce (version: 7.6)
  • Once the Xyce installation is complete, please make sure to add Xyce binary to $PATH environment variable.

Other notice:

  • Python 3.7 is used in this generator.
  • All the required tools need to be loaded into the environment before running this generator.
