Summary

test_support provides shared Python infrastructure for XMOS simulation and testbench code. It includes helpers for running xsim from pytest, interacting with simulated ports and pins, comparing simulator output, reading XE metadata, and modelling resolved bus wires in Python testbenches.

Features

  • Python wrapper for the xCORE simulator XSI interface.
  • Pytest-oriented simulator runners and output comparison helpers.
  • Simulator thread support for Python-driven testbench activity.
  • Resolved wire model for buses with multiple named drivers.
  • Python access helpers for XE files.
  • Python code coverage support for xsim traces.

Known issues

  • None

Development repo

Required tools
