TIMES -- a tool for modelling and implementation of embedded systems TIMES is a modelling and schedulability analysis tool for embedded real-time systems, developed at Uppsala University in 2001. It is appropriate for systems that can be described as a set of preemptive or non-preemptive tasks which are triggered periodically or sporadically by time or external events. It provides a graphical interface for editing and simulation, and an engine for schedulability analysis.
