Pervasive Automotive ElectronicsEnabled By Embedded Systems Technologies

Digital RF

The use of TPMS and RFID systems within anautomobile for safety and security systemshas created the need to develop and measurereal-time RF systems that can efficiently monitorvehicle operation and status.

Automotive Network

The increasing use of LANs has added new designchallenges as various serial data technologies

and applications such as CAN, LIN, MOST, andFlexRay are integrated into automotive designs.

Digital Analysis

Using Electronic Control Units (ECUs) to controlboth essential and non-essential automobilesystems is becoming the new industry standard.Based on digital technology, these ECUs requirea deeper understanding of complex timing andsignal integrity issues.

Power System

With the need for more energy efficient automobiles,power systems have become more complex.

Hybrid and clean burning diesel technologies requireadvanced electronic control systems to ensuresafe and environmentally responsible operation.

Automotive Network

Distributed control and safety systems intoday’s modern vehicles are made possible bythe use of multiple bus systems. These integratedbus systems must interact with the environment andcommunicate vital information throughout the entire vehicle.

The latest automotive designs utilizeseveral different technologies andprotocols, such as CAN, LIN, MOST,and FlexRay, which must coexist withinthe network.

Debugging and testing this type of network topologycan be challenging and time consuming. You need toolsthat can quickly and easily decode the various networkprotocols and time correlate network communication datawith external events triggered by sensors or transducers.

Tektronix instruments are used as the primary testdevice for analyzing automotive distributed networks.These tools can automatically decode standardautomotive buses and provide protocol level viewsof data sequences. Mixed Signal Oscilloscopes andlogic analyzers also provide innovative trouble-shootingcapabilities and comprehensive support for monitoring,triggering, and decoding small parallel buses. Tektronixinstruments ensure measurement confidence andsupport your need to more efficiently debug and testautomotive designs.

It has been estimated that electronics account forapproximately 25 percent of the value of today’sautomobile. This figure is estimated to rapidly increaseto nearly 40 percent in the future. The average new carcomes with a variety of Electronic Control Units (ECUs)managing everything from safety and stability toentertainment. These ECUs can include any combinationof memory, microprocessors (µP), microcontrollers (µC),and/or digital signal processors (DSP). Effective debugof ECU designs, including FPGA debug, requires acomprehensive toolset that not only provides a way tovisualize digital signal operation but also delivers timecorrelated views of both digital and analog information.

Tektronix solutions can provide digitalrepresentations of a large number ofsignals allowing you to make precise timingmeasurements, identify signal integrityissues, perform margin testing, as well asmonitor and time correlate multiple systembuses providing total system visibility.

The ability to present a variety of views and different levelsof abstractions of both hardware and software informationgives you a comprehensive view of system operation,which allows you to quickly interpret testing results.

New safety and monitoring system technologies in theautomotive design arena have moved towards RF andwireless as the enabling technology.

Tire pressure monitoring, keyless entry,and immobilizer systems are examplesof technologies containing RF signals thatare often triggered by external eventswhich create profiles that are intermittentin nature; present one moment, absentthe next, and variable over time.

These transient, infrequent signals are difficult to discoverand measure using traditional spectrum analysis tools.Tektronix' range of real-time signal analyzers, withDPX® technology, acquire up to 292,000 spectrummeasurements per second, compared to 50-100 witha traditional spectrum analyzer. DPX® technology enablesfast discovery, triggering, capturing and analysis oftime-varying signals in correlated multi-domains (Time,Frequency, Amplitude, Pulse, Modulation, and Phase).

The Tektronix portfolio also offers the latest innovationswhen dealing with embedded RF designs, with mixed RF,analog and digital technologies. Tektronix designed theworld's first Mixed Domain Oscilloscopes (MDO), whichincludes a dedicated and integrated spectrum analyzerinput channel, providing time-correlation of spectrumanalysis with 4 channels of analog and 16 channels ofdigital, making it the ideal mixed-domain trouble-shootingand system verification tool for the automotive industry.

Tektronix signal generators also play an important role inautomotive electronics design and debug by providingyou with the ability to exercise your designs under“real-world” conditions. Arbitrary waveform and functiongenerators are used to recreate the most complex signalsthat are a part of today’s complex, mixed signalautomotive environment.
