Abstract

Systems and methods receive a model of a physical system. The model includes a virtual mechanical component that represents a physical mechanical component of the physical system, and a virtual transducer that represents a physical transducer of the physical system. The systems and methods include generating a wiring diagram that includes information for connecting the physical mechanical component or the physical transducer to a data processing device or an embedded system. The model may be executed by the data processing device or the embedded system to interact with the physical mechanical component or the physical transducer as part of Hardware-in-the Loop (HIL), Processor-in-the-Loop (PIL), or other simulation or testing.
