CAN - Verifies communication, error detection, and data integrity in CAN systems

Overview

CAN (Controller Area Network) is a critical communication protocol widely used in automotive and industrial systems. It enables efficient, real-time data transfer between embedded systems, ensuring robust and reliable operation in safety-critical applications.

The CAN VIP ensures compliance with ISO 11898, simulating various network conditions to verify the functionality of CAN controllers. It handles error detection, message prioritization, fault confinement, and real-time data processing, enabling early identification of potential design flaws

Key Features

  • Protocol Compliance: Verifies that CAN controllers adhere to ISO 11898 standards, ensuring proper message formatting and data transmission. It checks bus arbitration protocols to confirm compliant communication between devices.
  • Error Detection: Ensures that CAN controllers accurately detect errors during data transmission, including error frames and checksums. It supports error counters for identifying issues and maintaining data integrity.
  • Real-Time Data Processing: Simulates the real-time processing of high-priority and low-priority messages. It ensures that message scheduling meets time-sensitive application requirements for effective communication.
  • Multi-Master Support: Verifies the ability of CAN controllers to handle multi-master arbitration and bus access contention. It ensures seamless communication between multiple nodes on the network, even with simultaneous communication.
  • Fault Confinement: Ensures that faulty nodes are isolated without disrupting the entire network, maintaining communication integrity. It simulates bus-off behavior under fault conditions to test the system’s resilience.
