Hardware and software
The SPI-Simulyzer is an interface box with which on the one hand data can be read out quickly and easily, and on the other hand simulation data can be used to actively intervene in the process.

Facts about the SPI-Simulyzer
In addition to the standard version, Seskion also offers modified versions as well as advanced hardware and software solutions for special measurement requirements.
- Standard Windows Gui application (optional): The protocol-specific Gui application offers a wide range of settings from the definition of signals, baud rates and error detection to trigger events. The visualization of the SPI bus communication facilitates troubleshooting and can also be easily saved. The SPI data is recorded with time stamps, whereby both import and export of data is possible.
- API-ANSI-C (included in the box)
- LabVIEW Lib (optional)

Serial Peripheral Interface
The Serial Peripheral Interface (SPI) is a common bus system in automotive sensor technology. ECU and peripheral sensors are connected to each other according to the master-slave principle. Each station is connected to the Serial Clock (SCLK), MISO and MOSI lines. The master synchronizes the communication via the serial clock.
HiL-Simulation for Airbag ECU
To generate a complete HIL simulation for an airbag control unit, the internal acceleration sensor signals of the control unit (SPI) and the peripheral acceleration and pressure sensor signals (PSI5) must be connected. Also the ignition timing can be measured and analyzed by using the SQUIB box. Furthermore, a PC system connected to the simulators via a USB port/network is used for data processing.
Often up to 6 or more PSI5-Simulyzer are operated together with several SPI-Simulyzer. For coordination there is a superordinate configuration, which determines which Simulyzer is used, which signal traces are used by which Simulyzer and which detailed configurations are to be used with the bus parameters. By using the superordinate configuration, the operation of the API is very simple. A continuous control of the sensor signals can also be made.
