Abstract

We introduce a global design methodology for large-scale real-time systems; it is based on such concepts as data-flow analysis, sequential processes, communication links, abstract architecture. These concepts give us a guide for designing real-time systems; two tools are also introduced, having a specific action in the design process: OGIVE, a Petri net analyzer, makes the verification and the validation of the abstract structure; OSCAR, analytical queuing network, oriented, evaluates quantitatively some implementation choices of the real system. These tools are integrated very early in the design process to make us sure we shall not have dramatic regressions to do for, eventually, redesigning the system.
