Abstract

Mathematical models of the timed behaviour of system components form a hierarchy of timing concepts. This is demonstrated for systems that communicate via input and output streams. We distinguish non-timed streams, discrete streams with discrete and with continuous time, and dense streams with continuous time. We demonstrate how exchanges of the timing models during the system-development process are captured as classical abstraction steps.
