The SPI-Simulyzer is an interface box for fast and easy data readout on the one hand, and active process intervention through simulated data on the other.
In addition to the standard version, we also offer improved versions, as well as advanced hardware and software solutions for special measurement needs.
To build a complete HiL simulation for an airbag control unit, it is necessary to access both the control unit's internal acceleration sensor signal (SPI) as well as the peripheral acceleration and pressure sensor signals (PSI5). In addition, a SQUIB box can be used to measure and analyze ignition timing. Data processing is accomplished by connecting to the simulator's PC system via a USB interface or network.
In a typical configuration, up to six (or more) PSI5 emulators and multiple SPI emulators can be running at the same time. For synergistic operation, an upper level configuration is used to determine the signal traces used by each emulator and the detailed settings of the accompanying bus parameters. The upper level configuration simplifies API operation and allows continuous control of the sensor signals.
The Serial Peripheral Interface (SPI) is a common bus system in automotive sensor technology, where the ECU and the peripheral sensors are connected to each other according to the master-slave principle. Each node is connected to the serial clock (SCLK), MISO and MOSI lines. The master communicates synchronously via the serial clock.
