Over the past decade, the SoftwareDefined Vehicle (SDV) has moved from buzzword to baseline for most automotive companies. Hardwareled innovation is becoming harder to sustain, while software driven differentiation is opening up entire markets and delivering real competitive advantage. As with many advances that don’t come for free, however, testing and validating software integration in the actual vehicle has become a major bottleneck. For many automotive programs, this directly impacts delivery timelines, quality, and engineering effort. At Intellias, we have been researching this challenge closely for our clients, with the goal of offering a bespoke testing approach that leverages Softwareinthe-Loop (SIL).
