Abstract
We present a model-checking procedure and its implementation for the
automatic verification of embedded systems.
The system components are described as
Hybrid Automata---communicating machines with finite control and
real-valued variables that represent continuous environment parameters such
as time, pressure, and temperature.
The system requirements are specified in a temporal logic with stop watches,
and verified by symbolic fixpoint computation.
The verification procedure---implemented in the Cornell Hybrid Technology
Tool, HyTech---applies to hybrid automata whose continuous dynamics is
governed by linear constraints on the variables and their derivatives.
We illustrate the method and the tool by checking safety, liveness,
time-bounded, and duration requirements of digital controllers, schedulers,
and distributed algorithms.
