Using This Manual
This manual introduces you to the HP 64146A/B 7700 Series Emulator
as used with the Softkey Interface.
This manual:
Shows you how to use emulation commands by executing
them on a sample program and describing their results.
Shows you how to use the emulator in-circuit (connected to a
target system).
Shows you how to configure the emulator for your
development needs. Topics include: restricting the emulator
to real-time execution, selecting a target system clock source.
This manual does not:
Show you how to use every Softkey Interface command and
option; the Softkey Interface is described in theSoftkey
Interface Reference.
For the most part, the HP 64146A and HP 64146B emulators all
operate the same way. Differences of between the emulators are
described where they exist. Both the HP 64146A and HP 64146B
emulators will be referred to as the "HP 64146A/B 7700 Series
emulator" or "7700 Series emulator". In the specific instances where
HP 64146B emulator differs from HP 64146A emulator, it will be
described as "HP 64146B emulator".

Organization
Chapter 1 Introduction to the 7700 Series Emulator. This chapter briefly
introduces you to the concept of emulation and lists the basic features
of the 7700 Series emulator.
Chapter 2 Getting Started. This chapter shows you how to use emulation
commands by executing them on a sample program. This chapter
describes the sample program and how to: load programs into the
emulator, map memory, display and modify memory, display registers,
step through programs, run programs, set software breakpoints, search
memory for data, and use the analyzer.
Chapter 3 "In-Circuit" Emulation. This chapter shows you how to install the
emulator probe into a target system and how to use the "in-circuit"
emulation features.
Chapter 4 Configuring the Emulator. This chapter shows you how to restrict the
emulator to real-time execution, select a target system clock source,
allow background cycles to be seen by the target system.
Chapter 5 Using the Emulator. This chapter describes emulation topics which are
not covered in the "Getting Started" chapter.
Appendix A Using the Foreground Monitor. This appendix describes the
advantages and disadvantages of foreground and background monitors
and how to use foreground monitors.
Appendix B Using the Format Converter. This appendix describes the usage of the
file format converter.

Conventions Example commands throughout the manual use the following
conventions:
bold Commands, options, and parts of command syntax.
bold italic Commands, options, and parts of command syntax
which may be entered by pressing softkeys.
normal User specified parts of a command.
$ Represents the HP-UX prompt. Commands which
follow the "$" are entered at the HP-UX prompt.
<RETURN> The carriage return key.
