Support of Multiprocessor Systems

To increase the computational power for large test systems, two or more SCALEXIO Processing Units can be coupled. The systems are coupled via IOCNET to ensure sufficiently large bandwidths. For convenient modeling, you still have just one overall project in the configuration software, ConfigurationDesk.

Adjustable I/O Scale

For comprehensive I/O requirements, the DS2655 FPGA Base Board can be extended with I/O modules. The example simulator setup on the right includes six DS2655 with 30 I/O modules and three Processing Units. Altogether, the system provides more than 500 I/O channels that are available via Hypertac connectors. The computation performance and the outstanding IOCNET I/O access let you run the complete simulation with sample times of less than 20 µs (input-to-output latency of less than 2x sample time). The SCALEXIO system can be adapted to all project requirements by dSPACE Engineering Services.

Controlling and Simulating Electric Motors

The new DS2655M2 Digital I/O Module adds 32 digital I/O channels to the DS2655 FPGA Base Board, letting you capture or generate more digital signals, e.g., for position sensors. Furthermore, the I/O channels can be configured as senders or receivers for RS232- and RS485-based communication. With the appropriate FPGA-based programming, you can thus simulate protocol-based position sensors (such as SSL, EnDat, and HIPERFACE) and digital encoders (such as incremental encoders). The FPGA is programmed for each case via AMD® Vitis TM Model Composer HDL Library. The FPGA application generated by the dSPACE FPGA Programming Blockset is then easy to import into dSPACE ConfigurationDesk to configure the entire SCALEXIO system graphically. The DS2655 FPGA Base Board can be connected with up to five I/O modules via a ribbon cable, offering a highly flexible number of available channels.

Synchronization

Due to the short sample times, jitter effects have to be reduced as far as available. Depending on the I/O channel requirements, different synchronization methods are possible. To minimize the jitter between two or more DS2655 FPGA Base Boards, including their modules, for gate driver capturing, the stacks are synchronized with each other via the appropriate I/O channels. This lets you synchronize multiple boards with a jitter of two FPGA clocks.

The SCALEXIO EMH Solution provides a ready-to-use FPGA application with a comprehensive I/O library for processor-based HIL simulation of electric motors. You can use it to configure the simulation of up to two electric motors on one DS2655 FPGA Base Board from within ConfigurationDesk. Thanks to the predefined function blocks, you no longer have to program or generate FPGA code. The fast I/O of the DS2655M1 Multi-I/O Module and the integrated angular processing unit (APU) with a resolution of 8 ns let you use high-resolution I/O to measure applications in the areas of pulse width modulation (PWM) and position sensor simulation (PSS). The variable I/O channel mapping and the flexible support of up to five DS2655M1 Multi-I/O Modules let you tap the hardware’s full potential. You do not have to replace hardware to switch from processor-based simulation to FPGA-based simulation. You can simply continue to use the existing hardware system.

Flexible Adaptation

Controlled electric drives are a key technology in numerous engineering applications. Therefore, handling a large number of applications requires a high degree of flexibility, especially for servo controllers in industrial automation. And with all the possible configuration options for the servo controller software, there is a high number of variants, entailing an enormous testing workload. As the necessary controlled systems and real parts can be replaced by simulation models, setups and changes of the test scenario can be done quickly. With automated testing on a HIL simulator, these tests are then accelerated significantly. In addition to the servo controller, you can also test the energy management system if a regenerative unit is part of your system. For this, dSPACE offers simulation models for grid simulation.
