VirtualNEXUS™
VirtualNEXUS™ from LTTS runs your production ECU software — Linux, QNX, RTOS, AUTOSAR and bare-metal/Non-AUTOSAR — inside a virtual ECU, surfacing defects months before physical hardware, HIL benches, or prototype vehicles are ready.
Software is scaling. Validation should scale with it.
Modern vehicle programs are software programs — yet validation still waits on physical ECUs, HIL benches, and prototype vehicles that arrive late, cost heavily, and are shared across teams. That queue simply doesn't scale with timelines.
HIL-bound testing
Software validation is throttled by limited bench availability and scheduling conflicts.
Program-specific virtualization
Proprietary environments are difficult to reuse beyond the program they were built for.
Variant-driven validation queues
Every additional ECU or software variant adds sequential validation pressure instead of enabling parallel iteration.
Hybrid Setup
Running physical ECUs from suppliers with virtual ECUs
Siloed toolchains
Development, testing, and validation tools often remain disconnected across teams.
Costly simulation platforms
Commercial tools can become expensive and inflexible where customization is needed.
Vehicle platform level testing
Running multiple vECUs at near real time performance
The result: Your software teams wait for benches, not validation results.

What Sets VirtualNEXUS™ Apart
Validation moves upstream, with functional Left-Shifts, feature integration, diagnostics and network validation into SIL earlier in the V-cycle.
HIL capacity is preserved, with reduced load on physical benches – freeing them for safety-critical and hardware-dependent validation.
Variants run in parallel, enabling testing of multiple ECU targets, software variants, and platform configurations without sequential bench queues.
System behavior is validated earlier, it surfaces OS, scheduling, communication and multi-domain interaction issues before late-stage integration.
Silicon boundaries stay clear, keeps hardware-driver-level and silicon-dependent testing on real hardware, avoiding overclaiming.
AI-assisted workflows, fast-track vECU creation, generating and configuring builds from existing artifacts.
Business Impact – Gains Across Time, Cost, and Delivery
Start in SIL earlier and run multiple variants in parallel, shifting 70–80% of functional and feature validation off shared benches.
Surfaces functional, diagnostics, network, and compound system defects before hardware is available.
Reduce HIL/test bench load by 70% per execution cycle across programs.
Level 3.5 execution bridges the gap between fast early simulation and late hardware accuracy.
Drive Your Product Lifecycle — with VirtualNEXUS™
Walk through the Level 3.5 architecture live, mapped to one of your own ECU targets — and see production software running before hardware is available.
VirtualNEXUS™ is LTTS' modular virtualization and simulation framework that runs production ECU software inside a virtual ECU, helping teams validate software earlier and identify issues before physical hardware, HIL benches, or prototype vehicles are available.
VirtualNEXUS™ supports Linux, QNX, RTOS, AUTOSAR, Android, and Non-AUTOSAR environments. Its architecture is designed to support multi-OS execution, hypervisor-based systems, and modern software-defined vehicle platforms.
Yes. VirtualNEXUS™ supports synchronized multi-ECU simulation, enabling teams to validate interactions, communication flows, and system-level behavior across multiple virtual ECUs at near-real-time performance.
Yes. VirtualNEXUS™ supports flexible deployment across cloud and on-premises environments, enabling teams to reuse virtual assets and validation workflows across programs and infrastructures.
A virtual ECU (vECU) is a software-based representation of an ECU. VirtualNEXUS™ runs production software inside the vECU to simulate the target environment and uncover defects earlier in the development cycle.
By shifting a significant portion of validation into Software-in-the-Loop (SIL) testing, VirtualNEXUS™ enables earlier testing and parallel development, helping reduce reliance on shared HIL benches and physical hardware resources.
Yes. VirtualNEXUS™ integrates with existing validation ecosystems through XIL-based test automation and FMI-based connectivity, allowing teams to leverage their current test automation and model-based development workflows.
VirtualNEXUS™ complements physical validation by shifting suitable testing earlier in the development cycle. Hardware-dependent and silicon-specific testing still requires real ECUs and HIL systems.
