Applications and system integration

Applications with the SPI-Simulyzer

Product background and integration into existing test setups.

HiL test setup with PSI5, SPI and SQUIB

Connected test setup

HiL simulation for airbag ECUs

A complete HiL simulation for an airbag ECU combines internal acceleration sensor signals via SPI with peripheral acceleration and pressure sensor signals via PSI5. The SQUIB Box measures and analyzes ignition timing. A PC system processes the data and connects to the simulators via USB or a network.

Six or more PSI5-Simulyzers are often used alongside several SPI-Simulyzers. A higher-level configuration assigns devices and signal traces and defines the bus parameters. This simplifies API operation and enables continuous monitoring of the sensor signals.

Technical background

Serial Peripheral Interface

The Serial Peripheral Interface (SPI) is used in automotive sensor technology. An ECU and peripheral sensors are connected using the master-slave principle.

Devices use the Serial Clock (SCLK), MISO and MOSI lines. The master synchronizes communication via the serial clock. Master-slave connections can be arranged in a cascade or star topology.
