When Is Robustness Verification Complete?


Understandably, hardware designed for an aircraft, or indeed any safety critical application, must be robust. I also believe that all engineers wish to verify their designs as thoroughly as possible, anyway. However, there are limiting factors; most notably the high complexity of most designs. Since we are unable to discover and verify the design against all abnormal conditions, the main questi... » read more

At the end of February, I attended the Aero Show in India - and what a show it was. So many exhibitors from around the world, including all main players from the commercial and military sides of the aerospace industry. Visitors could see everything required to build a modern aircraft: from small components like specialized ICs, cables and connectors up to big parts, such as the jet engines... » read more

Traceability is becoming increasingly important in most engineering projects, if only on the grounds of ‘good practice,’ and it is specifically required for projects that have to meet safety standards such as DO-254 and ISO 26262. To provide traceability, you must maintain the relationships between all aspects of a project; from the system-level requirements through implementation and ve... » read more
