HP 16500C LogicAnalysis System

HP 16505A PrototypeAnalyzer

Rapid Insight forDesigners of Complex,High-Speed DigitalSystems

The digital systems you design aregrowing more complex every day.Today’s trends include the following:

•More buses

•Faster, wider buses

•Multiple processors

•Increasing architectural complexity:– More intelligence hidden in silicon– Large internal caches– Pipelining and out-of-order

execution– Hierarchies of buses

Problems can show up at prototypeverification, in hardware-softwareintegration, or in conformance orcompatibility testing. The roots ofthose problems may lie in architec-ture, logic design, timing, or analogeffects.

To help you solve these problemsquickly, the HP 16500C logic analysissystem and HP 16505A prototypeanalyzer let you look at your design’sbehavior from every angle—fromcode execution to analog signals. Allviews are displayed together, time-correlated, on the HP 16500C or HP 16505A screen.

With the HP 16505A prototypeanalyzer, you can view the samemeasurement data simultaneously indifferent display modes, includingwaveform, listing, chart, and statisti-cal distribution. Drag-and-dropmarkers provide time correlationacross all displays.

The powerful cross-domain trigger-ing of the HP 16500C is indispensablefor solving problems in complex digital systems. Triggering on codeexecution or bus cycles, for example,can establish a context for findingthe cause of problems in timing oranalog behavior.

Unleash Your Power to Explore

You want to concentrate on yourdesign and apply your brain powerto problem solving. In addition, youwant tools that are easy to learnand use so you can gain insightquickly. The HP 16500C’s intuitiveuser interface harnesses the powerof the HP 16500C measurementmodules to tackle your problems.

The HP 16505A prototype analyzerprovides additional analysis capa-bilities and a large-screen, windoweduser interface to the HP 16500C logicanalysis system, to help you discov-er the root cause of your toughestdesign integration and debug problems quickly. The HP 16505A’smeasurement, analysis, and displaytools are located in a toolbox in themain window. You can drag anddrop the appropriate tools onto theworkspace and connect the tools tocustomize your environment.Measurement tools contain the con-figuration, format, and trace setupcontrols for the HP 16500 measure-ment modules.

If you don’t use a logic analyzer fre-quently, you’ll especially appreciatethe HP 16505A and 16500C. Withtheir intuitive interface, you’llimmediately start using them pro-ductively, instead of wasting timerelearning the interface each time.

The HP 16505A prototype analyzerhelps you quickly solve yourtoughest design integration anddebug problems. Simultaneousviewing of source, trace, andwaveform displays enables you toquickly track down cross-domaincause and effect. Move from chartor histogram overview of busactivity to detailed timing or ana-log waveforms in seconds—orview them all simultaneously.

Get the Best View with

Multiple, Sizable Windows

You can individually size each win-dow in the HP 16505A display up tothe full width of the local display, atresolutions up to 1024 x 768. 1280 x 1024 resolution is availablewith option 001, additional videoRAM, and a local monitor that sup-ports 1280 x 1024 resolution.Waveform, histogram, and chartdisplay windows can be dynamical-ly resized with the mouse. Simplydrag the mouse across the area youwant to view in more detail, and thewindow automatically rescales theviewing area.

Timing and analog waveforms canbe individually sized and colored toemphasize important channels.Waveforms can be reduced in sizeto view more channels, to give youa broad overview of system activity.You can view up to 100 individualwaveforms simultaneously.

You can resize the state listingwindows to the maximum screendimensions, and vary the text sizefor ease of viewing. You can alsodynamically reorder system labelsto optimize visual comprehension.

Multiple instruments can transmitdata to a single display window,which makes it easy to correlatedata from multiple domains.

Take The Fast Track to Insight

Figure 6.

Multiple windows in

the HP 16505A pro-

totype analyzer let

you view and analyze

a problem in many

different ways—

simultaneously.

Correlate Data with

Drag-and-Drop Markers

Display windows have two localand two global markers. Globalmarkers provide time-correlationacross multiple displays of datacaptured on the same run. As youmove a global marker in one win-dow, markers in the other windowsfollow. Local markers can measuretime intervals in a single windowwithout moving the global markers.

Find the Answers in Real-World

Data with Postprocessing

See just the address bus valuesyou want using the HP 16505A’spattern filter tool. Or use the pat-tern filter on a data bus to seethose data values that correspondto a certain variable value.

The pattern filter is placedbetween the source of the mea-surement data and one or moredisplay tools. It filters the datagoing to the display tool, so yousee only the data of interest. Youcan also see data both before andafter filtering. You can even cas-cade pattern filters. In all cases,the data is time-correlated.

The pattern filter can be used withany data, including analog andstate. Combine the outputs of multi-ple pattern filters to create displaysusing the X-Y chart display tool—for example, to track the value of avariable as conditions change.

Debug Complex

Microprocessor Systems

Customize the way you view theactivity in multiprocessor systemsfor insight into their complexbehavior. Data captured from anyprocessor or bus can be viewed inany display. You can create uniquetiming or listing displays to viewjust the data you need to under-stand a problem.

Connect to Your TargetSystem with HP Probesand Preprocessors

HP offers the most effective solu-tions for your hardest probingrequirements. HP’s innovativeprobing technologies offer opti-mum probing access for today’sfine-pitch, surface-mount IC pack-ages by easily connecting todevices with hundreds of pins.

Reliable connection is a must inprobing. HP’s unique probing tech-nologies make dependablemechanical and electrical connec-tions to the target.

The performance of any real-world measurement system canonly be as good as the probes. HPprobing systems are designed formaximum bandwidth and mini-mum loading of the target, so whatyou see is a true representation ofthe target’s behavior.

Preprocessors and inverse assem-blers make it easy to analyzemicroprocessor and bus activityby making the physical connectionto the target and disassemblingbus states into microprocessorassembly language. HP and HPChannel Partners provide hun-dreds of preprocessors andadapters for HP logic analyzers,offering broad support for micro-processors, industry standardbuses, and system interfaces. HPintroduces new preprocessors asnew processors become available.

Connect to the World and Your Team Memberswith LAN

Work from the convenience ofyour office, with the target systemlocated in a lab. You and otherteam members located in differentcities—or different countries—canwork together concurrently onproblems, using the same logicanalysis system and observing thesame target system.

Use the LAN to import data intoyour workstation or PC for convenient post-capture analysisand documentation. Build a commondatabase of target behavior so allteam members have access to a

Trigger and CorrelateMeasurements BetweenHP 16500-Series Modules

The intermodule bus in the HP 16500C is the key to cross-trig-gering and time-correlation amongmodules. Any module can armother modules using the intermod-ule bus. The other modules can betriggered immediately upon beingarmed, or wait after arming untiltheir own trigger conditions aresatisfied. The delay from recogniz-ing the trigger condition to armingother modules on the intermodulebus depends on the module andthe trigger conditions, but is typi-cally 100 ns.

A port-out BNC connector allowsthe intermodule bus to trigger orarm external devices. Externalinputs can be used to arm HP 16500C modules with the port-inconnector.

Data from different modulesacquired on the same group runcan be time-correlated. The resolu-tion and accuracy of time correla-tion depends on the individualmodules. The common intermod-ule bus clock that tracks individ-ual module trigger times has a res-olution of 2 ns.

Have Control at Your Fingertips

DIN connectors for a PS-2 key-board and mouse are provided onthe HP 16500C. The HP E2427Bkeyboard is available for the HP 16500C and includes an overlayfor the special function keys. A key-board is convenient for enteringlabels, for example. A PS-2 mouseis standard with the HP 16500C.

A mouse and keyboard are bothprovided with the HP 16505A proto-type analyzer.
