D9110AUTP Automotive Protocol Trigger and Decode

D9010AUTP

Automotive protocol trigger and decode software for Infiniium oscilloscopes

Introduction

The D9010AUTP software package for Infiniium oscilloscopes gives you the ability to trigger and decode on a large and ever-expanding suite of low-speed automotive serial protocols: CAN, CAN-FD, CAN-XL, LIN, FlexRay, and SENT. This package applies to the Keysight MXR, EXR, 9000, 90000, S, V, Z, and UXR-Series Infiniium Oscilloscopes.

Product Overview

This document is designed to help you understand what is available in D9010AUTP. For assistance in using the software, please reference the latest user’s guide, programmer’s guides, and online help for Infiniium available on Keysight.com.

Keysight’s D9010AUTP oscilloscope automotive option helps electronic system designers test and debug the physical layer of automotive serial buses faster. CAN, CAN-FD, CAN-XL, LIN, FlexRay, and SENT serial buses are the backbone for communication among many separate controllers, sensors, actuators, and ECUs located throughout automotive and industrial designs. These serial bus interfaces provide content-rich points for debugging and testing. However, since these protocols transfer bits serially, using a traditional oscilloscope has limitations. Manually converting captured 1s and 0s to protocol requires significant effort, cannot be done in real-time, and includes potential for human error. Also, traditional oscilloscope triggers are not sufficient for specifying protocol-level conditions. This software makes it easy to debug and test designs that include these buses using your Infiniium oscilloscope.

• Set up your oscilloscope to show CAN/CAN-FD/CAN-XL, LIN, or FlexRay protocol decode in less than 30 seconds
• Get access to a rich set of integrated protocol-level software triggers
• Save time and eliminate errors by viewing packets at the protocol level
• Use time-correlated views to quickly troubleshoot serial protocol problems back to their timing or signal integrity root cause
• With the CAN-dbc symbolic trigger and decode capability, engineers can now test the physical layer of this differential bus at a higher abstraction level

CAN

The differential Controller Area Network (CAN) bus is used extensively in all of today’s automobiles for drive-train and body control. This protocol was developed by Bosch more than 30 years ago, and it is still considered the “workhorse” serial control bus of the automobile. The CAN bus has also been heavily adopted for industrial and medical equipment control applications.

D9010AUTP includes a suite of configurable protocol-level trigger conditions specific to CAN, CAN-dbc, CAN-FD, and CAN-XL. When serial triggering is selected, the application uses software-based triggering or hardware-based serial triggering. With protocol triggering, the oscilloscope takes signals acquired using either a scope or digital channels and reconstructs protocol frames after each acquisition. It then inspects these protocol frames against specified protocol-level trigger conditions and triggers when the condition is met.

CAN XL

CAN XL is the third-generation CAN standard being developed by CAN in Automation (CiA). Although CAN XL provides full backward compatibility with CAN FD, the frame format has been extensively updated. CAN XL follows the concept of CAN FD with a low-speed arbitration phase and a high-speed data phase. However, the CAN XL data phase speed is specified to reach 10 Mbps or more, depending on the transceiver capabilities and physical layer components. Another key characteristic of CAN XL is that the payload length can be as large as 2048 bytes, enabling it to handle extra large files commonly required for applications such as the connection of radar sensors, eCall devices, and microphones.

The CAN XL decode setup is merged to the existing CAN/CAN FD protocol decoder menu with a separate data rate sample point selection. The decoder will display the fields of the CAN-XL frames in the waveform viewer like other protocols would. Various search capabilities of CAN XL would enable the user to search the decoded packet of interest.

CAN XL has two modes of operation – FAST mode and SIC mode (or slow mode). The fast bit rate at the data phase higher than 5 Mbps is enabled by using a CAN SIC XL transceiver. The D9010AUTP triggers and decodes the SIC mode (or slow mode) signal in the arbitration phase as well as the fast mode signal in the data phase correctly. It also handles the CAN XL protocols implemented with the CAN HS/FD/SIC transceivers.

The D9010AUTP software is compatible with the Infiniium oscilloscopes. To use CAN XL protocol trigger and decode, use the Infiniium oscilloscope with the software version 11.30 or higher for MXR/EXR/UXR models or version 6.72 patch 1 or higher for legacy Infiniium models. The D9010AUTP license on the Infiniium scope is extended to cover the CAN XL protocol trigger and decode.
