Technical notes for embedded test workflow evidence

Use these notes to understand one workflow problem at a time before changing tools or starting a larger implementation.

testing / hil · Updated Jun 20, 2026

Your HIL Test Passed. Your System Failed. Welcome to the Simulation Gap.

Why hardware-in-the-loop testing creates false confidence, how a 37.73% compute-latency gap between simulation and embedded hardware was measured in UAV research, and what refinery safety systems, ghost configuration settings, and silent callback failures teach us about testing what actually matters.

Therac-25: When Testing Is a Matter of Life and Death

A case study of the Therac-25 radiation therapy disasters – six accidents, multiple deaths, and the testing lessons that changed medical software forever.

Why Your Embedded Test Team Spends Most of Their Time Doing Dishes – And It's Not in Any Budget

Engineers spend days configuring test stands, chasing opaque errors, and rebuilding one-off setups. Forum analysis confirms: the majority of pain themes are configuration-related. C-suite never sees it.

So You're Building a Rocket. Your First System Is the Test System.

A launch is a terrible first integration test. What rocketry teaches about building test infrastructure before you need it – and what happens when you don't.

From Pass/Fail to Defensible Evidence: What the EU Cyber Resilience Act Means for Your Test Workflows

In our experience, most embedded test workflows are not ready for what the CRA requires for traceable test evidence.

Your Test Framework Should Be a REST API, Not a Desktop App

Why CI/CD and LabVIEW/TestStand don't mix – 322 forum posts, 793 pain rows, and $220K/year in handoff tax. A case study in what breaks when test tools are desktop-first.

The Handoff Tax: Why Your Embedded Test Team Loses 20-40% of Its Engineering Budget Between Tools

Every tool boundary, every specialist dependency, every compliance deadline – the hidden cost of handoffs in embedded test. What it is, why it compounds, and what to do before December 2027.

architecture / orchestration · Jun 12, 2026

Your tools work fine. The handoffs between them are the problem.

A six-layer way of seeing an embedded test workflow – from physical devices to test evidence – that makes handoff gaps visible and closable, without replacing any tool.

evidence-pack / export · Jun 11, 2026

Your export pipeline is lying to you. Not about the result – about the evidence.

Exporting test results to XML, CSV, or PostgreSQL preserves data but drops the context engineers need to trust results six months later. Map one workflow's evidence chain.

evidence-pack / embedded-test-workflow · Jun 10, 2026

The difference between test logs and trusted evidence

A test log records what happened. A trusted evidence pack preserves enough setup, run, and review context to make the result useful later.

workflow-mapping / example · Jun 10, 2026

Example: mapping one embedded HIL workflow [fictitious]

A fictitious but realistic walkthrough of mapping one embedded HIL workflow – showing where setup, tool handoffs, and evidence context get lost.

hil-sil / repeatability · Jun 10, 2026

Why HIL test repeatability is a workflow problem

HIL repeatability depends on more than the simulator. Setup, versions, environment, operator steps, and evidence handoffs all affect trust.

labview-teststand / tool-handoff · Jun 10, 2026

Where LabVIEW and TestStand handoffs lose workflow context

LabVIEW and TestStand can remain valuable tools while the workflow around them still loses setup, evidence, and review context.

labview / vector · Jun 10, 2026

LabVIEW + Vector CANoe: when two strong tools don't talk

Both tools are capable on their own. The problem is the handoff between them – and it is a problem that repeats in labs everywhere.

test-tool-migration / workflow-mapping · Jun 10, 2026

Map one test workflow before replacing another tool

Before a test tool migration, map one workflow to see whether the real problem is setup, handoff, evidence, or repeatability.

diagnostic-workshop / paid-diagnostic · Jun 10, 2026

What a paid workflow diagnostic should deliver

A paid diagnostic is a narrow, time-boxed exercise. Here is what you should expect before committing: inputs, outputs, duration, price test, and decision criteria.

embedded-test-workflow / tool-handoff · Jun 10, 2026

Why embedded test labs fail between tools

Most embedded test labs do not have a missing-tool problem. They have a between-tool problem – and replacing one tool rarely fixes it.
