PUFFS

PyTest Unified Framework for FPGA Simulation — a Python-based testing framework that combines pytest with cocotb simulation for verifying hardware designs.

evolvablehardware/PUFFS

Overview

PUFFS provides a unified testing environment for FPGA designs by integrating pytest's testing conventions with cocotb's hardware simulation capabilities. This allows hardware designs to be verified using familiar Python testing workflows, with channel-level abstractions enabling Python-based testbench interactions.

Key Features

  • pytest integration for conventional testing workflows
  • cocotb simulation for Verilog/SystemVerilog designs
  • Channel-level abstractions enabling Python-based testbench interactions
  • Gold model support with Python reference implementations alongside RTL

Project Structure

  • src/models/ — Python gold models (reference implementations)
  • src/unit/ — Unit tests
  • src/verilog/ — RTL designs
