As timing constraints and resource allocations are strict, it is necessary to verify schedulability, safety and liveness properties. In this paper, we formally specify real-time software using hybrid automata and verify its schedulability using both deductive refinement theory and scheduling theory. In this case, the above real-time software consists of periodic processes and a fixed-priority preemptive scheduling policy on one CPU. Using our proposed methods, we can uniformally and easily specify real-time software and verify its schedulability based on hybrid automata. Moreover, we can verify its schedulability at design stage.}, pages = {527--533}, publisher = {Institute of Electrical and Electronics Engineers (IEEE)}, title = {Deductive Schedulability Verification Methodology of Real-Time Software using both Refinement Verification and Hybrid Automata}, year = {2003} }
