Timing is an important concern when designing an embedded system. While lots of researches on hard real-time systems focus on design-time analysis, monitoring the corresponding runtime behaviors are seldom investigated. In this paper, the authors investigate the conformity problem for runtime inputs of a hard real-time system. They adopt the widely used arrival curve model which captures the worst/best-cases event arrivals in the time interval domain and propose an algorithm to on-the-fly evaluate the conformity of the system input w.r.t. given arrival curves.
