Modern vehicles are increasingly software-defined, with dozens of ECUs, networks, and domains working together in real time. As software takes on more vehicle functionality, testing must go beyond individual components. Even when ECUs pass their own tests, integration issues often surface only once systems are combined. This is compounded by tighter coupling between hardware and software, where behaviors such as timing and memory usage are hard to fully replicate in simulation, leaving gaps until testing reaches the target hardware.

Meanwhile, ISO 26262 compliance requires robust safety evidence for ASIL-classified functions, and cybersecurity requirements under UN R155 and ISO 21434 call for continuous validation rather than a one-off check. The rise of over-the-air updates adds further pressure, as each release carries regression risk that can ripple across shared platforms and increase liability exposure.

eInfochips Automotive Testing Services support end-to-end Hardware and Software Testing from requirements through to system qualification. This helps address these challenges because validation can no longer be a final checkbox; it needs to be thorough, continuous, and built into development from the start.
