We develop a novel model-based hardware-in-the-loop (HIL) framework for optimising energy consumption of embedded software. Software components are specified as networks of parameterised timed input/output automata, which are translated into executable code run on a microcontroller connected to an executable plant model and a power monitor. We use timed Petri nets as an intermediate representation of the executable specification, which facilitates efficient code generation and fast simulations. The framework is able to produce optimal values of timing parameters that minimise energy usage, without compromising a given safety requirement, together with a probabilistic power consumption model derived from real measurement data. Our framework uniquely combines the advantages of rigorous distributed real-time specifications with accurate power measurements and online power model construction.
