Abstract

We describe a layered approach to the specification and verification of real-time systems. Application processes are specified in the CSR application language, which includes high-level language constructs such as timeouts, deadlines, periodic processes, interrupts and exception-handling. Then, a configuration schema is used to map the processes to system resources, and to specify the physical communication links between them. To analyze and execute the entire system, we automatically translate the result of the mapping into the CCSR process algebra. CCSR characterizes CSR's resource-based computation model by a priority-sensitive, operational semantics, which yields a set of equivalence-preserving proof rules. Using this proof system, we perform the algebradc verification of our original real-time system.
