Although SystemC and its AMS extensions are widely promoted for the design of heterogeneous systems, very few complete cases studies are actually available. In this work, we present a digital and an analog version of a motor speed controller, and detail various modeling approaches. In the digital version, the executable specification is refined to a TLM virtual prototype that runs SW code on a QEMU emulated RISC-V, to study the effect of HW/SW design decisions on the physical system dynamics. In the analog version, the controller equation is mapped to a SystemC AMS model and refined from the discrete- time to the continuous-time domain. By simulating this system, we illustrate the effectiveness of SystemC and SystemC AMS for heterogeneous design space exploration.
