The three laws of safe embedded systems
This short article is part of an ongoing series in which I aim to explore some techniques that may be useful for developers and organisations that are beginning their first safety-related embedded project.
Developing software for a safety-related embedded system for the first time
Developing a safety-related embedded product is not the same as writing ordinary firmware, and this article lays out eight practical steps to get you started. Using a washing-machine controller as a running example, it covers scoping, key requirements, hazard analysis, applicable standards, platform and MCU choices, runtime monitoring, and prototyping. The checklist helps teams prepare for verification, testing, and later certification work.
How to test a Tesla?
Tesla’s autopilot system is moving from headlines to real roads, and that raises an immediate testing question. This short post revisits the UK legal angle and points to early driver reports covered by the Express, giving a quick snapshot of how people are starting to evaluate the system in practice.
“Smarter” cars, unintended acceleration – and unintended consequences
Smarter cars are arriving fast, but the software tricks behind them may be creating new safety and compliance risks. This post connects Tesla’s autopilot, the VW emissions scandal, and a reported Porsche throttle-delay case to ask whether automotive standards and regulations are keeping pace with increasingly intelligent vehicle control systems.
