Zonal Architecture Twin Modeling & SIL Clusters
VehicleTwins eliminates hardware dependency bottlenecks in modern SDV development. Simulating complex multi-zonal vehicle platforms in high-density Kubernetes clusters, engineers run hundreds of AUTOSAR Classic and Adaptive vECUs in deterministic lockstep, executing millions of regression test miles overnight.
Zonal Twin Backplane Zonal Architecture
Central Controller: Zonal Twin Backplane — Virtual TSN / CAN-XL Bus
Zonal Control Units & TSN Ring
- Zonal Central HPC Emulator (ARM64)
- Front Zone vECU (AUTOSAR Classic)
- Rear Zone vECU (Powertrain Logic)
- Virtual Time-Triggered Ethernet Bridge
- Automated Fault Injection Framework
Virtual Time Decoupling, ASIL D SIL Testing & Deterministic Co-Simulation
Hardware-in-the-Loop (HIL) test racks cost millions and suffer from physical wiring bottlenecks. VehicleTwins encapsulates physical zonal harnesses, CAN XL/Ethernet buses, and multicore microcontrollers into containerized virtual machines that run faster than real time or pause deterministically for sub-instruction debugging.
Core Engineering Areas
- AUTOSAR vECU Cloud Orchestration — Compiling AUTOSAR Classic BSW and application software components (SWCs) for x86_64 and ARM64 target runners with cycle-accurate timing.
- Virtual Time Synchronization — Eliminating race conditions and nondeterministic simulation drift by slaving all virtual ECUs to a discrete-event central simulation manager.
- Automated Fault Injection — Systematically corrupting memory bits, dropping network frames, and shorting virtual pins to prove that vehicle safety mechanisms respond correctly.
