Mixed reality systems overlay real data with virtual information in order to assist users in their current task, they are used in many fields (surgery, maintenance, entertainment). Such systems generally combine several hardware components operating at different time scales, and software that has to cope with these timing constraints. MIRELA, for Mixed Reality Language, is a framework aimed at modelling, analysing and implementing systems composed of sensors, processing units, shared memories and rendering loops, communicating in a well-defined manner and submitted to timing constraints. The paper describes how harmful software behaviour, which may result in possible hardware deterioration or revert the system's primary goal from user assistance to user impediment, may be detected such as (global and local) deadlocks or starvation features. This also includes a study of temporal properties resulting in a finer understanding of the software timing behaviour, in order to fix it if needed.
