Verification Report

Overview

This document summarizes the validation artifacts of the Embedded Sensor Interface Module (ESIM) tests run via native_sim.

Test Execution Logging

Environment

  • Target OS: Linux native_sim (Zephyr)
  • Host Tools: Python 3.11 with Pytest
  • Framework: Pytest 8.x

Known Limitations

  1. As explicitly stated in the design, because native_sim operates under Linux User Space scheduling, there is inherent jitter preventing absolute sub-20ms hard real-time latency verification. Tests compensate slightly for OS pipe jitter.
  2. Hardware assertions, signal integrity, and logic bounds (RAM/Flash space footprint) cannot be perfectly represented computationally and will require physical evaluation metrics on ultimate platform hardware transitions.
