ISO26262: Freedom of interference – What is that?

Veröffentlicht am

There are four essential measures in the development of safety-critical systems. Design of safe systems Measures to minimize random hardware errors Measures to minimize systematic hardware and software errors Organizational measures (management of functional safety) Particularly in the design of safe systems, the principle of Freedom of interference is a powerful measure. What’s this? The […]
