The ‘Digital Twin’ in Hardware in the Loop (HiL) Simulation: A Conceptual Primer
Michael Grieves first uttered the term ‘digital twin’ in 2003, and since then much ink and many pixels have been spilled over it. We’ll keep it relatively brief. While ‘digital twin’ can mean many things to many people, it has a more restricted set of understandings when we speak in the context of real-time simulation and/or Hardware in the Loop (HiL) testing. To begin to explain this closer-cropped meaning, let’s start by thinking of a […]
