The HP 64780A Emulator
Description
The HP 64780A emulator supports the Motorola 68360 and 68EN360
microprocessor operating at clock speeds up to 33 MHz. The emulator supports
both 5V and 3.3V operation. The emulator plugs directly into a PGA socket, and it
can be plugged into a PQFP target system using optional accessories.
In this manual, the emulator is referred to by Model Number 64780A, and the
Motorola microprocessor is referred to by MC68360.
The emulator plugs into the modular HP 64700 instrumentation card cage and
offers 80 channels of processor bus analysis with the HP 64794A or HP 64704A
emulation-bus analyzer. Up to eight megabytes of emulation memory may be
installed on the probe. High performance download is achieved through the use of
a LAN (standard in the HP 64700B; optional in HP 64700A) or RS-422 interface.
An RS-232 port and a firmware-resident interface allow debugging of a target
system at remote locations.
For software development, the HP AxCASE environment is available on SUN
SPARCsystems and on HP workstations. This environment includes an ANSI
standard C compiler, assembler/linker, a debugger, the HP Software Performance
Analyzer that allows you to optimize your product software, and the HP Branch
Validator for test suite verification. The C compiler, assembler/linker, and
debugger are also available for MS-DOS systems.
Language support is also available from several third-party vendors. This capability
is provided through the HP 64700’s ability to consume several industry standard
output file formats.
Ada language support is provided on HP 9000 workstations by third-party vendors
such as Alsys and Verdix. An Ada application developer can use the HP emulator
and any compiler that generates HP/MRI IEEE-695 to do exhaustive, real-time
debugging in-circuit or out-of-circuit.
Motorola’s initial release of the MC68360 was "Revision A1". HP used that
original version in its first emulator shipments. Since that time, Motorola has
released follow-on versions "B1," "B2," "C," and "MC68MH360". Each
v

subsequent version fixed errata from the previous version. HP is currently using
33-MHz Revision C in its HP 64780A emulator.
Motorola continues to ship prior revisions of the MC68360, and the MC68MH360.
If you would like to use one of the non-Revision C parts in your HP 64780A
emulator, HP offers an upgrade kit. Contact your local HP field engineer for
ordering information.
Along with the upgrade kit, you will have to supply your own non-Revision C part
(order separately). You will install your non-Revision C part in the processor
socket on the emulator probe by following instructions supplied with the upgrade
kit.

In This Book
This manual covers the HP 64780A emulator for the MC68360 microprocessor. It
is divided into the following parts:
Part 1, “Installation,” shows you how to install and connect all of the
emulator/analyzer hardware in the card cage, connect the card cage to a host
computer in several typical configurations, and connect the emulator probe into the
demo board and into your target system.
Part 2, “Service,” shows you how to install and update emulator/analyzer firmware,
solve problems you may encounter while using the emulator/analyzer, and obtain
replacement parts for the emulator/analyzer from Hewlett-Packard.
Part 3, “Terminal Interface Reference,” introduces the interfaces available to use
with the emulator/analyzer, and shows you how to use the terminal interface for the
emulator/analyzer.
This manual replaces the Terminal Interface Reference which accompanied earlier
HP emulators. For information on the Terminal Interface, see Part 3.
You should read the book Concepts of Emulation and Analysis when you have the
chance to do so; it contains a good conceptual introduction to the emulation
process, and also describes how an emulation monitor works. Another book, the
HP 64700 Card Cage Installation/Service Guide, tells you more about installation
and configuration of the HP 64700 Card Cage. If you have a problem with the
emulator and don’t understand how to fix it, a listing of HP Sales and Service
offices is in the Support Services Guide in the back of this binder.

What you need
Equipment supplied
The minimum system contains:
•HP 64780A 68360 PGA Emulator Probe
•Demo target system (shipped with the emulator probe).
•HP 64748C Emulation Control card.
•HP 64794A/C/D Emulation-Bus Analyzer (deep analyzer with ) card, or
HP 64704A Emulation-Bus Analyzer (1K analyzer) card.
•80-Channel Analyzer Extender Ribbon Cable.
•HP 64700A or HP 64700B Card Cage.
Optional parts are:
•HP 64172A 256-Kbyte Memory Modules for additional memory depth.
•HP 64172B 1-Mbyte Memory Modules for additional memory depth.
•HP 64173A 4-Mbyte Memory Modules for additional memory depth.
•HP 64708A Software Performance Analyzer.
•HP 64701A LAN Interface card (HP 64700A only).
Equipment and tools needed
In order to install and use the MC68360 emulation system, you need:
•Flat-blade screwdriver with shaft at least 5 inches long (13 mm approx).
•Torx T-10 screwdriver (if installing the optional LAN card for the
HP 64700A).
The illustrations in this manual show the HP 64700B Card Cage. The locations of
some components may be slightly different if you are using an HP 64700A Card
Cage.

Antistatic precautions
Printed-circuit boards contain electrical components that are easily damaged by
small amounts of static electricity. To avoid damage to the emulator boards, follow
these guidelines:
•If possible, work at a static-free workstation.
•Handle the boards only by the edges; do not touch components or traces.
•Use a grounding wrist strap that is connected to the HP 64700 chassis.
Note If you already have a modular HP 64700 Series Card Cage and want to remove the
existing emulator and insert an HP 64780A emulator in its place, the HP 64700
Series generic firmware and analyzer firmware may NOT be compatible, and the
software will indicate incompatibility. In this event, you must purchase a Flash
EPROM board to update the firmware. Instructions for installing this board and
programming it from a PC or HP 9000 are provided in the HP 64700 Card Cage
Installation/Service manual. Instructions for installing and updating emulator
firmware are covered in Chapter 5, "Installing/Updating Emulator Firmware".
Note If you already have a modular HP 64700 Series Card Cage and want to remove the
1K analyzer and install the deep analyzer in its place, the analyzer firmware will be
updated by your installation because the analyzer firmware is contained on the
analyzer card.
