Abstract
Real-time software is required to react within certain time constraints. Aimed at forecasting early during the design process whether the design approach chosen will fulfill those time constraints, while avoiding costly prototyping, two different methods have been developed: open-loop dynamic evaluation of time-critical parts of executable design specifications, and animating a closed-loop system, consisting of the executable design specifications, coupled to a dynamic simulation model of the physical system involved. Both methods are explained using examples.
