Openwater LIFU Verification Tests

openLIFU-test-scripts

Utility and verification scripts for OpenLIFU hardware validation, burn-in, and data analysis.

Overview

This repository contains:

• Thermal and burn-in verification scripts for transmitter and console behavior
• Self-test and hardware sanity scripts
• Data processing helpers for logs and report generation
• Historical and legacy test content kept for reference

The main active package is verification, which contains most test runners and shared test logic.

Repository Layout

• verification/: Primary test package and production requirement test scripts
• tools/: Helper utilities and support scripts
• tutorials/: Example and tutorial content
• logs/: Output logs produced by test runs
• plots/: Generated plots and visualizations
• legacy/: Older scripts retained for backwards reference
• deprecated/: Retired scripts that should not be used for new runs
• build/, dist/: Build artifacts

Requirements

• Python 3.10 to 3.12
• OpenLIFU SDK installed and accessible
• Device access permissions for serial/USB interfaces when running against hardware

From pyproject.toml:

• Package name: verification
• Runtime dependency: openlifu-sdk

Setup

1. Create and activate a virtual environment.

Windows PowerShell:

python -m venv .venv
.\.venv\Scripts\Activate.ps1

2. Install the package in editable mode from repository root:

pip install -e .

Common Test Scripts

In verification/

• prodreqs_tx_short_verification_test.py

  • Short transmitter verification path
  • Useful for communication and functional checks

• prodreqs_tx_long_verification_test.py

  • Long-duration heating/burn-in workflow scaffold

• prodreqs_base_class.py

  • Shared base class, telemetry monitoring, limits, and CLI argument parser

Running Tests

Because several scripts use package-relative imports, run them from the repository root with module syntax.

Examples:

python -m verification.prodreqs_tx_short_verification_test --frequency 400 --num-modules 2 --test-runthrough

python -m verification.prodreqs_tx_long_verification_test --frequency 400 --num-modules 2

Frequently Used CLI Options

Most production requirement scripts consume argument parsing from verification/prodreqs_base_class.py.

Useful options include:

• --frequency KHZ
• --num-modules N
• --test-case N
• --test-runthrough
• --simulate
• --external-power
• --console-shutoff-temp C
• --tx-shutoff-temp C
• --ambient-shutoff-temp C
• --temperature-check-interval S
• --temperature-log-interval S
• --log-dir DIR
• --verbose or --quiet
• --skip-logfile

Logs and Outputs

• Runtime logs are typically written under logs/
• Additional outputs may be created in:
  • plots/
  • verification/*.csv
  • project root files like combined_logs.xlsx

Use --log-dir to direct log output to a custom path.

Safety Notes

When running against physical hardware:

• Ensure emergency stop and power cutoff procedures are known before starting
• Confirm shutoff temperatures and monitoring intervals are appropriate
• Prefer running with conservative thresholds during initial validation

Troubleshooting

• Import errors:

  • Ensure you run via python -m verification.<module> from repo root
  • Confirm pip install -e . completed successfully

• Device connection failures:

  • Verify hardware is connected and powered
  • Confirm SDK/device drivers are installed
  • Re-run with --verbose for more detailed logs

• No log file generated:

  • Check --skip-logfile was not set
  • Confirm write access to the selected log directory

Development Notes

• Some files in legacy/ and deprecated/ are intentionally preserved and may not reflect current behavior
• Keep new work in verification/ unless intentionally adding migration content
• Maintain script compatibility with Python 3.10-3.12
