Key Use Cases
Tools in Detail
dSPACE VEOS
PC-based simulation platform for virtual ECU testing. Runs AUTOSAR SWCs and BSW on a PC with simulated OS and communication stacks. Supports FMI for plant model co-simulation.
Synopsys SILVER
Virtual ECU platform that compiles actual ECU binary code for PC execution. Enables high-fidelity SIL testing with real production code, including MCAL emulation layers.
Vector vVIRTUALtarget
Lightweight virtual ECU environment integrated with CANoe. Runs compiled AUTOSAR application code in a simulated environment with virtual bus communication.
ETAS ISOLAR-EVE
Virtual ECU environment from ETAS for running RTA-BSW and application software on PC. Integrated with INCA for virtual calibration sessions.
Siemens SIMCENTER
Comprehensive simulation platform for vehicle dynamics, thermal, and NVH analysis. Provides validated plant models for ADAS development and chassis control testing.
CarMaker (IPG)
Leading vehicle dynamics simulator for ADAS and autonomous driving development. Provides realistic traffic scenarios, sensor models, and road environments for closed-loop testing.
CarSim (Mechanical Simulation)
High-fidelity vehicle dynamics simulation for chassis control development. Math-based models run in real-time for HIL and faster-than-real-time for SIL testing.
Industry Context
Traditional development - write code, flash ECU, test on HIL - creates a bottleneck limited by physical hardware availability. Virtual ECU technology removes this by allowing software execution on PCs and cloud servers, enabling unlimited parallel testing, CI/CD integration, and testing months before hardware. Teams run thousands of test cases nightly in cloud SIL environments, catching regressions in hours rather than weeks. For autonomous driving, virtual simulation is essential - the only practical way to test billions of driving scenarios.
Typical Workflow
Virtual ECU creation (VEOS, SILVER, vVIRTUALtarget) from the AUTOSAR build connects to plant models (CarMaker for ADAS, SIMCENTER for powertrain). Developers run local tests for quick feedback; CI/CD pipelines run thousands of tests in parallel on cloud servers. As hardware arrives, the same test cases migrate to HIL (SCALEXIO/LABCAR) with minimal changes. For ADAS/AD, CarMaker generates millions of driving scenarios far exceeding real-world test drives.
Selection Guide
Pro Tips
Start virtual ECU testing from first integration - don't wait until software is 'ready.'
Ensure SIL and HIL use the same test cases and pass criteria - divergent strategies undermine shift-left value.
Invest in scenario generation tools (OpenSCENARIO/OpenDRIVE) - manual scenario creation doesn't scale.
Be aware of SIL timing limitations - timing-dependent behaviors may differ from real hardware.
Use FMI (Functional Mock-up Interface) for plant model exchange between tools to avoid vendor lock-in.
