Abstract:

Professional electronic equipment, in many fields, has a relatively long expected lifetime (several decades). During their existence, they can be subject to stresses linked to their environment (variations in temperature, humidity, etc.) as well as to changes in components in the event of a breakdown, situations which can have an impact on their performance. Thus, in order to minimise redesign and production costs, it is essential to ensure, from the design phase of such equipment, maximum reliability and durability and, in particular, to guarantee that it will generate as little electromagnetic interference as possible and that it will itself be resilient to such interference throughout its life cycle.

One of the root causes of possible malfunctions in such electronic equipment is the integrated circuit. Consequently, the objective of the proposed thesis is to develop models to predict the performance of integrated circuits with respect to electromagnetic disturbances throughout the serial life of the equipment they compose. In the long term, these models will be validated and incorporated into the data provided by the IC manufacturers in order to facilitate the design of electronic products that are both functional and durable.
