Skywater + OpenFPGA: Open-Source FPGAs

Introduction

FPGA tape-outs using the open-source Skywater 130nm PDK and OpenFPGA

Quick Start

#Clone the repository and go inside it
git clone https://github.com/LNIS-Projects/skywater-openfpga.git
python3 SCRIPT/repo_setup.py --openfpga_root_path ${OPENFPGA_PROJECT_DIRECTORY}

---

• If you have openfpga repository cloned at the same level of this project, you can simple call

  python3 SCRIPT/repo_setup.py

Otherwise, you should provide full path using the option --openfpga_root_path

Directory Organization

• Keep this folder clean and organized as follows
  • DOC: documentation of the project
  • ARCH: Architecture XML and other input files which OpenFPGA requires to generate Verilog netlists
  • BENCHMARK: Benchmarks to be tested on the FPGA fabric
  • HDL: Hardware description netlists for the FPGA fabrics
  • SDC: design constraints
  • SCRIPT: Scripts to setup, run OpenFPGA etc.
  • TESTBENCH: Verilog testbenches generated by OpenFPGA
  • PDK: Technology files linked from skywater opensource pdk
  • SNPS_ICC2: workspace of Synopsys IC Compiler 2 Keep a README inside the folder about the ICC2 version and how-to-use.
  • MSIM: workspace of verification using Mentor ModelSim

---

• Note:
  • Please ONLY place folders under this directory. README should be the ONLY file under this directory
  • Each EDA tool should have independent workspace in separated directories.
