This work describes Verus, a new tool to be used in the formal verification of realtime systems. In Verus the designer specifies the system to be verified in a C-like language, and uses temporal logic model checking and quantitative timing analysis to verify its correctness. The information produced by our tool can help in verifying a real-time system in many ways. It not only assists in determining its correctness, but also provides insight into the behavior of the system. This allows for a better understanding of the system and in some cases it even suggests optimizations to the design.

We have used this tool to analyze several real-time systems of industrial complexity, such as an aircraft controller, a robotics controller and a distributed heterogeneous system. In all cases we have been able to determine the temporal correctness of the system. In several instances the results produced suggested modifications to the design that resulted in more efficient systems.
