FlexRay measurement system from Agilent, Decomsys

Agilent Technologies Inc. and Dependable Computer Systems GmbH (Decomsys) have introduced a measurement system that promises the highest-level FlexRay triggering and protocol decode measurements available in an oscilloscope. This solution allows automotive designers who use embedded microprocessors to verify proper signal integrity of their FlexRay signals and proper timing of the time-triggered communication bus.

The measurement system combines an Agilent 6000 Series mixed signal oscilloscope (MSO) with a Decomsys BusDoctor 2 protocol analyzer to provide the first time-correlated slot/segment boundary display of the global FlexRay timing schedule on an oscilloscope.

Automotive communication bus
The FlexRay serial bus is an automotive communication bus with a time-triggered, deterministic architecture. This higher-performance and fault-tolerant serial bus is gaining rapid adoption in the design of some of today's higher-end automobiles including BMW's X5 SUV, where it initially is being used to support a suspension application. Because of the fault-tolerant nature of the FlexRay protocol, FlexRay technology is expected to be used in the near future for many safety-critical applications such as steer-by-wire, brake-by-wire and collision-avoidance systems.

When used in combination with the Decomsys BusDoctor 2 protocol analyzer, Agilent's FlexRay option for the 6000 Series mixed signal oscilloscopes offers a robust set of FlexRay frame, slot and error triggering, including the ability to trigger on specific FlexRay communications qualified on base-cycle and cycle-repetition.

Standalone tester
Designers can see a synchronous and time-correlated display of segment and slot-timing boundaries by importing a FIBEX file that defines the global FlexRay schedule directly into the 6000 Series mixed signal oscilloscope. This capability allows the system to be used as a standalone tester (no external PC required). Alternatively, the Decomsys BusDoctor 2 and MSO can be configured for synchronous operation using Decomsys' VISION software package. This type of system configuration provides higher-level FlexRay protocol analysis measurements on the PC and time-correlated FlexRay measurements on the oscilloscope's display.

The Agilent N5432A FlexRay triggering and real-time decode option for the 6000 Series mixed signal oscilloscope is priced at $2,500.
