Times: A tool for schedulability analysis and code generation of real-time systems

TIMES is a tool suite designed mainly for symbolic schedulability analysis and synthesis of executable code with predictable behaviours for real-time systems. Given a system design model consisting of (1) a set of application tasks whose executions may be required to meet mixed timing, precedence, and resource constraints, (2) a network of timed automata describing the task arrival patterns and (3) a preemptive or non-preemptive scheduling policy, TIMES will generate a scheduler, and calculate the worst case response times for the tasks. The design model may be further validated using a model checker e.g. UPPAAL and then compiled to executable C-code using the TIMES compiler. In this paper, we present the design and main features of TIMES including a summary of theoretical results behind the tool. TIMES can be downloaded at www.timestool.com.
