Abstract
Synchronous Reactive Modelling provides an optimal framework for the
modular decomposition of programs that engage in complex patterns of
deterministic interaction, such as many real-time and communication
entities. This paper presents an approach which includes performance
modelling techniques in the Synchronous Reactive Modelling method
supported by
Esterel.
It defines a methodology based on timing
and probabilistic quantitative constructs which complete the
functional models. A monitoring mechanism provides performance results
during the simulation. This methodology is applied to a protocol
modelling case study. Performance metrics are computed and compared
with known reference results.
Key words: Performance Engineering, Synchronous Reactive Models,
Real-Time & Embedded Systems, Model Development, Instrumentation,
Simulation and Monitoring.
