Multibus Analyser for FlexRay
Based on the experience made in analyzing automotive bus systems in the CAN area, IXXAT developed its Multibus Analyser. The Multibus Analyser is operating together with the FlexRay CCM PC interface and provides functions for receiving, transmitting as well as tracing and the interpretation of FlexRay and CAN messages.
Function Overview
Reception and display of messages (receive module)
The receive module of the Multibus Analyser provides the online display of the FlexRay and CAN messages (raw data). The messages can be displayed in scroll and overwrite mode. In scroll mode the FlexRay messages are displayed with timestamp, ID, cycle and channel number. In the overwrite mode the messages are displayed in the order of either the identifier, the channel number or FlexRay cycle at cycle reception and are always updated by the latest received messages.
As a special feature, the receive module highlights the contents of a message which has changed in order to make the changes obvious.
The message status vector is also displayed and interpreted, static and dynamic messages are tagged. The receive module provides filter functions for selecting and displaying data with respect to message, cycles, IDs, channel number or message status.
The trace module allows the online logging of the entire communication on hard disk. The received messages (with timestamp, cycle number, ID and channel) as well as relevant errors are recorded for offline evaluation.
The trace module has a manual start/stop function and a trigger/filter mode. Recorded messages can be converted to various formats.
The multibus functionality of the analyser allows the user to analyze FlexRay and CAN systems synchronously.
The signal module enables the interpretation of the signals transmitted in a FlexRay or CAN message. Similar to the receive module, a scroll and an overwrite mode is available for displaying the interpreted signals. The display can be completely customized in order to meet the users requirements. Furthermore, the signal module provides a cycle time monitor. The data interpretation rules are provided according to the ASAM Fibex data description standard. This allows the visualisation of the network, whereby the received signals can be assigned to the devices.
Transmitting of messages (transmit module)
The Multibus Analyser can also be operated as a network node providing the transmission of pre-defined messages.
Scripting Host and .net Interface
The scripting host is a powerful interface which allows the user to adapt the Multibus Analyser quickly and easily to specific simulation and analyzation tasks. For test and device simulation the interface provides functions for the transmission and reception of FlexRay and CAN messages.
The scripting host supports the Windows scripting languages C# and Visual-Basic-Spript as well as .NET visual components.
CAN modules
In addition to the FlexRay function modules the Multibus Analyser provides various modules for CAN analyzing and stimulation from the canAnalyser product (see canAnalyser).
