In the literature, several HIL specific applications are reported and simplified HIL simulators were built according to some specific purpose.<ref name=brake/><ref>A. Cebi, L. Guvenc, M. Demirci, C.

The strategy is restricted to the analysis of ECU outputs when excited by controlled inputs. In this case, a Micro HIL system (MHIL) offers a simpler and more economic solution.<ref name=palladino>A. Palladino, G. Fiengo, F. Giovagnini, and D. Lanzo, "A Micro Hardware-In-the-Loop Test System", ''IEEE European Control Conference'', 2009.</ref> Since complexity of models processing is dumped, a full-size HIL system is reduced into a portable device composed of a signal generator, an [[I/O]] board, and a console containing the actuators (external loads) to be connected to the ECU.

=== Aerospace and Defense ===

HIL simulation is used heavily due to the complexity of aerospace systems and the relative risk of accidents in [[Flight test|flight testing]]. Subcomponents such as computers, sensors, and avionics are either emulated in software or integrated with each other to create a representative simulation to test both system performance and failure modes. Typically, HIL simulation is utilised towards the latter stages of system development such as validation of [[software-in-the-loop]] (SILSIM) simulations. However, depending on the fidelity of the HIL simulation platform, they can also be used to validate design iterations in the preliminary design phases.

===Offshore systems===

In offshore and marine engineering, control systems and mechanical structures are generally designed in parallel. Testing the control systems is only possible after integration. As a result, many errors are found that have to be solved during the commissioning, with the risks of personal injuries, damaging equipment and delays. To reduce these errors, HIL simulation is gaining widespread attention.<ref>{{cite conference |first=T. A. |last=Johansen |first2=T. I. |last2=Fossen |first3=B. |last3=Vik |title=Hardware-in-the-loop testing of DP systems |conference=DP Conference |___location=Houston |year = 2005}}</ref> This is reflected by the adoption of HIL simulation in the [[Det Norske Veritas]] rules.<ref>DNV.
