Verification and Testing of Cyber-Physical Systems

Embedded systems are computerised systems that interact with their physical environment. They are usually called cyber-physical when they are largely distributed, and networking and security aspects play a major rule. Describing such systems requires to combine continuous-time and discrete-time components, together often referred to as hybrid systems.
