Solutions
The digital systems you design are
growing more complex every day.
Today’s trends include the following:
2
•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 prototype
verification, in hardware-software
integration, or in conformance or
compatibility testing. The roots of
those problems may lie in architecture, logic design, timing, or analog
effects.
To help you solve these problems
quickly, the HP 16500C logic analysis
system and HP 16505A prototype
analyzer let you look at your design’s
behavior from every angle—from
code execution to analog signals. All
views are displayed together, timecorrelated, on the HP 16500C or
HP 16505A screen.
With the HP 16505A prototype
analyzer, you can view the same
measurement data simultaneously in
different display modes, including
waveform, listing, chart, and statistical distribution. Drag-and-drop
markers provide time correlation
across all displays.

The powerful cross-domain triggering of the HP 16500C is indispensable
for solving problems in complex
digital systems. Triggering on code
execution or bus cycles, for example,
can establish a context for finding
the cause of problems in timing or
analog behavior.
Unleash Your Power
to Explore
You want to concentrate on your
design and apply your brain power
to problem solving. In addition, you
want tools that are easy to learn
and use so you can gain insight
quickly. The HP 16500C’s intuitive
user interface harnesses the power
of the HP 16500C measurement
modules to tackle your problems.
The HP 16505A prototype analyzer
provides additional analysis capabilities and a large-screen, windowed
user interface to the HP 16500C logic
analysis system, to helpyou discover the root cause of your toughest
design integration and debug
problems quickly. The HP 16505A’s
measurement, analysis, and display
tools are located in a toolbox in the
main window. You can drag and
drop the appropriate tools onto the
workspace and connect the tools to
customize your environment.
Measurement tools contain the configuration, format, and trace setup
controls for the HP 16500 measurement modules.

Viewing state, timing, and analog information together,
time-correlated on
the HP 16500C
screen, makes it easy
to find the cause of
problems.
Figure 3.
The HP 16500C logic
analysis system can
be operated using its
own built-in user
interface, without
the HP 16505A.
If you don’t use a logic analyzer frequently, you’ll especially appreciate
the HP 16505A and 16500C. With
their intuitive interface, you’ll
immediately start using them productively, instead of wasting time
relearning the interface each time.

prototype analyzer
is a measurement
server that uses
the HP 16500C’s
real-time measurement power. It
adds a largescreen, windowed
display and powerful analysis tools.

Take The Fast Track
to Insight
The HP 16505A prototype analyzer
helps you quickly solve your
toughest design integration and
debug problems. Simultaneous
viewing of source, trace, and
waveform displays enables you to
quickly track down cross-domain
cause and effect. Move from chart
or histogram overview of bus
activity to detailed timing or analog waveforms in seconds—or
view them all simultaneously.
Get the Best View with
Multiple, Sizable Windows
You can individually size each window in the HP 16505A display up to
the full width of the local display, at
resolutions up to 1024 x 768.
1280 x 1024 resolution is available
with option 001, additional video
RAM, and a local monitor that supports 1280 x 1024 resolution.
Waveform, histogram, and chart
display windows can be dynamically resized with the mouse. Simply
drag the mouse across the area you
want to view in more detail, and the
window automatically rescales the
viewing area.

Figure 6.
Multiple windows in
the HP 16505A prototype analyzer let
you view and analyze
a problem in many
different ways—
simultaneously.
Timing and analog waveforms can
be individually sized and colored to
emphasize important channels.
Waveforms can be reduced in size
to view more channels, to give you
a broad overview of system activity.
You can view up to 100 individual
waveforms simultaneously.
You can resize the state listing
windows to the maximum screen
dimensions, and vary the text size
for ease of viewing. You can also
dynamically reorder system labels
to optimize visual comprehension.
Multiple instruments can transmit
data to a single display window,
which makes it easy to correlate
data from multiple domains.

Tool icons can be
dragged and dropped
onto the HP 16505A
workspace, where they
connect automatically.
Correlate Data with
Drag-and-Drop Markers
Display windows have two local
and two global markers. Global
markers provide time-correlation
across multiple displays of data
captured on the same run. As you
move a global marker in one window, markers in the other windows
follow. Local markers can measure
time intervals in a single window
without moving the global markers.
Find the Answers in Real-World
Data with Postprocessing
See just the address bus values
you want using the HP 16505A’s
pattern filter tool. Or use the pattern filter on a data bus to see
those data values that correspond
to a certain variable value.
5
The pattern filter is placed
between the source of the measurement data and one or more
display tools. It filters the data
going to the display tool, so you
see only the data of interest. You
can also see data both before and
after filtering. You can even cascade pattern filters. In all cases,
the data is time-correlated.
The pattern filter can be used with
any data, including analog and
state. Combine the outputs of multiple pattern filters to create displays
using the X-Y chart display tool—
for example, to track the value of a
variable as conditions change.
Debug Complex
Microprocessor Systems
Customize the way you view the
activity in multiprocessor systems
for insight into their complex
behavior. Data captured from any
processor or bus can be viewed in
any display. You can create unique
timing or listing displays to view
just the data you need to understand a problem.

Time-correlated
waveform and
source code windows enable you to
isolate the root
cause of your system integration
problems.

Starting with an
overview of the entire
measurement (such
as chart), use filters
to discard uninteresting data, to give you
just the information
you need.
