D-Space introduces the new SIL-HIL co-simulation, a solution that for the first time enables a seamless connection between software-in-the-loop (SIL) and hardware-in-the-loop (HIL) test environments. This allows for a consistent, flexible, and "shift-left"-oriented testing process, significantly increasing development efficiency.

Users benefit from the new co-simulation solution by being able to conduct tests as soon as individual components, whether as hardware or virtual ECUs (V-ECU), become available. The waiting time for complete hardware is eliminated, shortening development cycles and accelerating iterations. The co-simulation allows for a step-by-step, low-risk integration from SIL to HIL and aims for consistent artifacts, tests, and simulation models across the SIL and HIL environments. The co-simulation combines the PC-based simulation platform D-Space Veos for software-in-the-loop simulations and Scalexio, the modular and scalable real-time platform for hardware-in-the-loop and rapid-control-prototyping applications. Communication occurs via HSIL (Hybrid Simulation Integration Layer), an integration layer for coupling SIL and HIL simulations. The HSIL communication interface also enables third-party systems to be connected.

Tests of ADAS Control Units

Initial successful and typical applications of co-simulation include testing of ADAS control units, where high-performance computers in HIL and environmental simulations as well as other control units as SIL can be integrated, or development-accompanying tests of infotainment systems, where, for example, the infotainment device itself can be tested via HIL and the rest of the system via SIL methodology in combination.
"With SIL-HIL co-simulation, dSPACE sets new standards for testing flexibility in the automotive sector and supports OEMs and suppliers in making development processes more efficient," says Barbara Kempkes, Business Field Manager SIL Testing.
