Real-time embedded programs are time sensitive and, to trace such programs, the instrumentation mechanism must honor the programs' timing constraints. We present a time-aware instrumentation technique that injects program code with slack-based conditional instrumentation. The central idea is to execute instrumentation code only when its execution does not(More)
Debugging is an important phase in the embedded software development cycle because of its high proportion in the overall cost in the product development. Debugging is difficult for real-time applications as such programs are time-sensitive and must meet deadlines in often a resource constrained environment. A common approach for real-time systems is to(More)
Runtime monitoring aims at analyzing the well-being of a system at run time in order to detect errors and steer the system towards a healthy behavior. Such monitoring is a complementary technique to other approaches for ensuring correctness, such as formal verification and testing. In time-triggered runtime monitoring, a monitor runs as a separate process(More)
