Printing History

New editions are complete revisions of the manual. The date on the title page

changes only when a new edition is published.

A software code may be printed before the date; this indicates the version level of

the software product at the time the manual was issued. Many product updates and

fixes do not require manual changes, and manual corrections may be done without

accompanying product changes. Therefore, do not expect a one-to-one

correspondence between product updates and manual revisions.

68302 Emulation and Analysis

The HP 64746 68302 emulator replaces the microprocessor in your embedded

microprocessor system, also called the target system, so that you can control

execution and view or modify processor and target system resources.

The emulator requires an emulation analyzer that captures 64 channels of emulation

processor bus cycle information synchronously with the processor’s clock signal.

The HP 64703 Emulation Bus Analyzer meets this requirement, and it has an

external analyzer that captures up to 16 channels of external data.

You can use the HP 64704 or HP 64794 Emulation Bus Analyzers which have 80

channels; however, these analyzers do not have external analysis channels.

You can also use the HP 64706 Emulation Bus Analyzer which has 48 channels.

Because this analyzer has fewer channels, you cannot capture all the

microprocessor bus cycle information that you can with the other analyzers.

With the Emulator, You Can ...

•Plug into 68302 target systems.

•Download programs into emulation memory or target system RAM.

•Display or modify the contents of processor registers and memory resources.

•Run programs, set up software breakpoints, step through programs, and reset

the emulation processor.

With the Analyzer, You Can ...

•Trigger the analyzer when a particular bus cycle state is captured. States are

stored relative to the trigger state.

•Qualify which states get stored in the trace.

•Prestore certain states that occur before each normal store state.

•Trigger the analyzer after a sequence of up to 8 events have occurred.

•Capture data on signals of interest in the target system with the external

analyzer.

•Cause emulator execution to break when the analyzer finds its trigger condition.

With the HP 64700 Card Cage, You Can ...

•Use the RS-422 capability of the serial port and an RS-422 interface card on

the host computer (HP 98659 for the HP 9000 Series 300) to provide

upload/download rates of up to 230.4K baud.

•Easily upgrade HP 64700 firmware by downloading to flash memory.

With Multiple HP 64700s, You Can ...

•Start and stop up to 16 emulators at the same time (up to 32 if modifications

are made).

•Use the analyzer in one HP 64700 to arm (that is, activate) the analyzers in

other HP 64700 card cages or to cause emulator execution in other HP 64700

card cages to break.

•Use the HP 64700’s BNC connector to trigger an external instrument (for

example, a logic analyzer or oscilloscope) when the analyzer finds its trigger

condition, or you can allow an external instrument to arm the analyzer or break

emulator execution.

With the Graphical User Interface, You Can ...

•Use the emulator and analyzer under an X Window System that supports

OSF/Motif interfaces.

•Enter commands using pull-down or pop-up menus.

•Enter, recall, and edit commands using the command line pushbuttons.

•Enter file names, recalled commands, recalled values, etc., using dialog boxes.

•Set breakpoints by pointing the mouse cursor on a line in the mnemonic

memory display and clicking.

•Create action keys for commonly used commands or command files.

With the Softkey Interface, You Can ...

•Use the emulator and analyzer with a terminal or terminal emulator.

•Quickly enter commands using softkeys, command recall, and command

editing.
