An Off-line Scheduler and System Simulator for the Basement Tm Distributed Real-time Sys- Tem

BASEMENT is a distributed real-time architecture developed within the Swedish Road Transport Informatics Programme. BASEMENT is intended for vehicle internal use in the automotive industry. BASEMENT is holistic in that it covers application development as well as the hardwares and softwares that provide execution and communication support. The key constituents of BASEMENT are: resource sharing (multiplexing) of processing and communication resources, a guaranteed real-time service for safety critical applications, a best-e ort service for non-safety critical applications, a communication infrastructure providing e cient communication between distributed devices, and a software development method allowing resource independent and application oriented development of application software. This paper concentrates on software development. In particular, it presents two design tools: an o -line scheduler and a BASEMENT system simulator, together with an example illustrating their use.
