As software deployment velocity continues to outpace physical hardware availability, relying strictly on traditional Hardware-in-the-Loop (HIL) setups is rapidly shifting from a core strategy to an operational bottleneck.
In this episode, host Suresh Sivavarman sits down with Sangeeta Theru, Virtual Validation Platform Lead at Stellantis, to explore how the automotive industry is evolving from hardware-centric testing frameworks to software-first engineering environments. Sangeeta breaks down how Stellantis leverages a "shift-left" strategy by scaling Software-in-the-Loop (SIL) platforms to achieve faster time-to-market, minimize late-stage engineering risks, and drastically reduce physical vehicle prototype costs.
Whether you are an embedded software engineer, a system validation manager, or an OEM technical lead, this conversation offers a practical guide to demystifying Virtual ECUs (VECUs) and scaling digital validation workflows.
