Static timing analysis apparatus and method for distributed real-time embedded software

A static timing analysis apparatus for distributed real-time embedded software, comprising:

• a task analyzer analyzing tasks per processor based on either a source code of real-time embedded software if the source code exists or a design model of a corresponding piece of the real-time embedded software if the source code does not exist;
• a message analyzer analyzing messages per network based on the source code and the design model;
• a task worst-case response time analyzer analyzing a worst-case response time of each task, which is taken account of a scheduling policy of a corresponding operating system at which said each task is operated, based on the task analysis result for each processor provided by the task analyzer and the message analysis result for each network provided by the message analyzer;
• and
• a task real-time analyzer analyzing whether the worst-case response time of each task analyzed at the task worst-case response time analyzer exceeds a deadline of the corresponding task.
