Central Gateway Control・Real-Time Target System Verification Tool for Multiple CANs

Synchronized measurement of multiple CAN communications (CAN/CAN-FD) at the same time, and simultaneous monitoring and logging of the behavior of internal processing (relaying and secure measures) of the MCU in the GW-ECU are also possible.

Vehicle network systems must become more sophisticated and reliable to achieve “Connected Cars” and “Automated Driving”.In the past, gateways for vehicle networks were configured to bundle networks of ECUs for each function, but recent vehicle network configurations have introduced “Central Gateways” that are hubs for each domain that serves as a control group and manage multi-channel vehicle data.
Advanced Driver Assistance Systems (ADAS) to realize increasingly sophisticated cooperative control among ECUs～In Automated Driving, the challenges of gateway relay processing are ensuring communication delay time between ECUs and relay software control that can withstand additions and changes to functional specifications.In addition to relay functions and ECU-to-ECU mediation, the planned roles of the central gateway include the ability to update ECU software (OTA), which is a requirement for Connected Cars, and the ability to remotely diagnose vehicles by connecting to the outside world via the Internet through infotainment.The core gateway is equipped with security measures against malicious threats from the outside world and also plays the role of blocking unauthorized intrusion.Therefore, it is also a challenge to verify the defense system of security measures.
RAMScope-EXG enables multiple measurements by combining a RAM monitor module that possible to observe the behavior of control processing (variable measurement) of a central gateway MCU and a CAN module that observes CAN/CAN-FD communication in an automotive network.Realization of synchronous measurement of multiple measurement modules allows for real-time coordination of the automotive networks and capture of gateway internal processing performance.It is also possible to create pseudo illegal message patterns of CAN/CAN-FD messages and send scenarios.Please use RAMScope-EXG (GT170 series) for the verification environment of secure measures.
