Designing Safety Critical Applications

A design toolbox for hardware, software and system Engineers.

This is a training for design engineers. It gives a common ground of knowledge needed for engineers to discuss and agree on design requirements with Safety Managers.

When a product is recommended to meet any Safety related norm, design engineers involved in the development of electronics hardware and software parts of such products need to speak the same language and understand the basics of Functional Safety.

During this training the attendees will be given a toolbox for entering a new state of mind: knowledge of when and why safety rules started becoming important in the realm of embedded systems, and how to effectively join a safety-first design process.
