Rapid prototyping of hardware using real-time HWIL simulation environments

Torres, Jonathan F.; Kowalchuk, Scott A.

The Navigation, Guidance, and Control (NGC) Department at Sandia National Laboratories conducts flight test programs where rapid proto- typing is essential. To successfully maintain schedule it is critical to have high confidence in the NGC hardware and software prior to integration testing. The NGC Department has developed a V-Model diagram approach to ensure high confidence with hardware and software prior to in- tegration testing within a rapid prototyping environment. The V-Model detailed design process flow describes a design approach for testing hard- ware and software early and often using hardware-in-the-loop (HWIL) and software-in-the-loop (SWIL) simulations.
