Designed for automotive vehicle manufacturers and Tier 1 suppliers, the offering combines agentic AI, physical AI-powered simulation and intelligent orchestration to help automate elements of vehicle software validation workflows and accelerate releases. As modern vehicles become increasingly software-defined, technological complexity, over- the-air updates and evolving regulatory frameworks are placing greater demands on the verification and validation processes. Automotive organizations face challenges of fragmented tool chains, manual workflows and labor-intensive compliance processes, creating a bottleneck between software development and release. As part of HCLTech's Industry AI solutions portfolio, this V&V offering for Auto leverages a simulation-first operating model that connects requirements, test creation, execution, analysis and compliance evidence across the validation lifecycle. The solution enables customers to automate validation workflows, expand scenario coverage, identify and investigate test failures faster, and maintain a continuous digital record linking requirements, test results and compliance reporting. HCLTech’s V&V for Auto combines HCLTech’s automotive engineering expertise, agentic AI capabilities and Validation Factory model with the NVIDIA stack, including NVIDIA Omniverse, NVIDIA Cosmos, NVIDIA Alpamayo, NVIDIA Omniverse NuRec and NVIDIA Isaac Sim, to generate and validate a wide range of scenarios in virtual environments, including rare and safety-critical conditions. This reduces reliance on physical testing, expands test coverage and improves visibility into release readiness. Leveraging the NVIDIA Agent Toolkit, this solution orchestrates multiple AI agents with reasoning powered by NVIDIA Nemotron open models across the V&V lifecycle. “Automotive software is evolving faster than traditional validation processes were designed to handle. Frequent software updates, increasingly complex vehicle systems and the need to demonstrate compliance across changing configurations can make validation slow, fragmented and difficult to scale. Powered by NVIDIA, HCLTech’s V&V for Auto is designed to help organizations shift from periodic, labor-intensive testing to continuous, intelligent validation, using simulation and AI to make software release decisions with greater speed and confidence,” said Pankaj Tagra, Chief Growth Officer and Global Head, Mobility at HCLTech. “Validation now sets the pace for software-defined vehicles. With NVIDIA Omniverse, Cosmos and Nemotron at its core, this solution leverages world-class simulation and AI capabilities to support automakers in their journey towards moving more testing into simulation, covering rare and safety-critical scenarios earlier and releasing software with greater confidence,” said Dr. Sebastian Scheurle, EMEA Industry Lead Automotive Enterprise, at NVIDIA.
