Engineers designing and integrating in-vehicle networks can monitor FlexRay protocol information in hexadecimal and decimal formats, analyze the electrical characteristics of a FlexRay signal using eye diagrams, time interval error plots and sync measurements with a Tektronix DPO/MSO4000 Series oscilloscope and the FlexRay Protocol Analysis Software
The PDF-D FlexRay Protocol Analysis Software offers the best solution in the industry for debugging and testing of FlexRay signals using the award winning Tektronix DPO4000 and MSO4000 Series oscilloscopes.
This software enables the designer to capture thousands of FlexRay messages and display the decoded data. The PDF-D FlexRay decode feature allows the users to view the decoded data in hexadecimal, decimal, octal and binary formats as specified. PDF-D Software overlays control and payload data of the FlexRay frame on the waveform for easy debugging FlexRay communication l issues. The protocol decode table highlights the header CRC, trailer CRC and eye diagram error frames (frames causing eye diagram failures) in red.
Signal Integrity: Electronic control units (ECU’s) should work in extreme operating conditions in an automobile. To ensure reliable operation of ECU’s at extreme operating conditions, FlexRay signal should have enough design margins. PDF-D Software’s signal integrity feature helps in quickly analyzing the electrical characteristics of a FlexRay signal. Advanced features such as eye diagram analysis, time interval error plot, and sync measurements enables the user to know the eye opening, jitter, and synchronization in a FlexRay network.
Features: Protocol Decode • Converts time domain waveform information into data domain and displays the contents in FlexRay message format
• Displays waveform and decoded data simultaneously in a single window allowing efficient debugging
• Ability to link any FlexRay frame or any message (data or address) to waveform allows efficient analysis of FlexRay communication
• Detailed view plots the waveform for the selected frame and overlays the decoded data on the waveform.
• Error frames are highlighted in red for easy debugging.
• ‘Find’ function helps in quickly locating the specific data or address out of thousands of decoded FlexRay messages
• Time stamp with reference to trigger position allows users to know the time from the frame to the trigger event
• Offline analysis with Ref waveforms, .ISF (Tektronix oscilloscope’s internal waveform file format) and, .CSV files
• Capability to save the decoded messages in .CSV forma
• Ability to view the eye diagram for selected message with the complete acquired data helps in pinpointing the cause for the
eye diagram failure
• Quick analysis of the eye diagram as per FlexRay standard
• FlexRay frames causing eye diagram errors are highlighted in red in the decode table
• Time interval error analysis for each frames helps in understanding the influence of oscillator stability in each FlexRay node
• Sync measurements enable the user to know time lapse between the sync frames
• Average bit time measurement
