SCALEXIO, dSPACE’s latest hardware-in-the-loop (HIL) technology, is now even more powerful with its new extension for a multi-processor (MP) simulation platform.
With the MP extension, users can connect several SCALEXIO multi-core processing units to create powerful simulation platforms for real-time computation. This makes it possible to develop embedded systems that require computationally intensive, high-fidelity simulation models to handle validation and verification tasks for the ever-growing complexity in vehicle systems.
Users can also create system-level or entire-vehicle-level integration testing platforms by combining existing SCALEXIO systems used for unit-level testing, thereby leveraging available infrastructure and reducing development costs.
To protect existing investments and provide computation extensibility with the latest processor technology, SCALEXIO processing units can also be coupled to dSPACE HIL systems based on DS1005, DS1006, and DS1007 processor boards.
Support for Multiple Processing Units
The central element of any SCALEXIO system is the SCALEXIO processing unit for computing simulation models. SCALEXIO systems can be coupled by inter-connecting processing units via IOCNET, dSPACE's network technology. IOCNET handles the exchange of very large data volumes while maintaining low I/O latency times. It also facilitates distributed I/O connections across long distances. IOCNET is a highly efficient and cost-effective inter-processor communication protocol developed especially to meet the requirements of distributed real-time simulation platforms.
The entire simulation model, computed across the multi-core, multi-processor platform, is configured with the dSPACE ConfigurationDesk tool used to deploy individual simulation models on processors. Filters can be configured to create specific views of the overall simulation model.
Coupling with DS100x-Based Hardware
IOCNET technology can also be used to connect SCALEXIO processing units to existing HIL simulators with dSPACE DS1005, DS1006, and DS1007 processor boards. This is a cost-effective way to add new SCALEXIO capabilities to existing systems. Data exchange and real-time synchronization of simulation systems are easy to configure.
For instance, a coupled system might benefit from SCALEXIO communication bus I/O cards when performing communication bus simulations that require the highest bandwidth and low latencies (e.g. CAN, LIN, FlexRay etc.)
Tests for All Domains and Variants
With the SCALEXIO multi-processing feature, dSPACE's extensive HIL solutions provide testing capability for ECU software across all vehicle domains and industries. All the options available for SCALEXIO and DS100x processor board coupling allow engineers to expand their existing test setups to meet growing project needs.
