The Simulyzer supports a wide range of SPI applications, including SPI clock rates from 10 Hz to 20 MHz and data lengths from 8 to 64 bits per data packet. Captured data can be visualized, recorded, and analyzed using Seskion’s software or integrated into custom systems via an open API.

Features and Capabilities

• Analyze, Measure, and Simulate
  The SPI-Simulyzer enables complete analysis of SPI signals and active simulation of SPI sensors or ECUs. Voltages, signals, and communication data can be precisely measured, generated, and recorded.
• Multiple Operating Modes
• ECU Mode: The Simulyzer acts as an SPI master, supplies connected sensors with voltage, and records communication with up to four SPI slaves.
• Sensor Mode: The Simulyzer emulates up to four SPI sensors (SPI slaves) by generating corresponding data for an external ECU.
• Passive Mode: SPI communication between ECU and sensors is passively monitored and recorded without influencing the bus.
• Flexible Interfaces
  The SPI-Simulyzer provides USB connectivity, an SD card slot for optional data logging, two SPI interfaces, analog/digital I/O, and an optional license-based CAN interface. Both single-ended and LVDS SPI variants are available.
• High Measurement Accuracy
  Precise voltage measurement and generation, a stable time base, and high-resolution analog and digital I/O ensure reliable and repeatable measurement results.
• Software and Integration
  Data visualization and analysis are performed using Seskion’s software tools. In addition, an open API allows seamless integration into existing test benches, automation systems, and custom toolchains.
  
  

Typical Applications
The SPI-Simulyzer is widely used in automotive electronics, sensor and ECU development, HIL environments, and laboratory setups. Its flexibility makes it suitable for both simple signal analysis and complex simulation and test scenarios.
