HPUSB, USB, and HPPCI Emulators User’s Guide 1-3
Getting Started
Installation Tasks
Perform the following tasks to safely install your USB- or PCI-based
emulator. Follow these instructions in the presented order to ensure
correct operation of your software and hardware.
Installing USB-Based Emulators
1. Install VisualDSP++. VisualDSP++ includes the USB driver needed
for your USB emulation hardware. If VisualDSP++ is already
installed, you do not need to install it again. VisualDSP++ can be
installed on Windows 2000, Windows XP, or Windows Vista.
Refer to the Installation Quick Reference Card for details.

Note: If you connect the ICE first, before installing VisualDSP++,
the Windows driver wizard will not be able to find the drivers to
install for the emulator to function.
2. Connect the USB cable between the USB assembly and a USB port
of your computer.
3. Verify driver installation. Refer to “Verifying Driver Installation”
on page 1-4.
Before connecting to a target, see the power-up/down procedures
in “Attaching the Cable to the Emulation Target” on page 1-6.

Installation Tasks
1-4 HPUSB, USB, and HPPCI Emulators User’s Guide
Installing PCI-Based Emulators
1. Install the HPPCI-ICE hardware. For instructions on installing a
PCI card into your computer, consult the documentation provided
by the computer manufacturer.
2. Install VisualDSP++. VisualDSP++ includes the HPPCI driver
needed for your PCI emulation hardware. VisualDSP++ can be
installed on Windows 2000, Windows XP, or Windows Vista.
Refer to the Installation Quick Reference Card for details.
3. Verify driver installation. Refer to “Verifying Driver Installation”
on page 1-4.
The driver must be installed before you start the HPPCI-ICE for
the first time.
Verifying Driver Installation
Before using your USB- or PCI-based emulator, verify that the driver
software is installed properly.
Open the Windows Device Manager and verify that the HPUSB-ICE,
HPPCI-ICE or USB-ICE appears under ADI Development Tools as
shown in Figure 1-1

HPUSB, USB, and HPPCI Emulators User’s Guide 1-5
Getting Started
Figure 1-1. Verifying Driver Installation

Attaching the Cable to the Emulation Target
1-6 HPUSB, USB, and HPPCI Emulators User’s Guide
Attaching the Cable to the Emulation
Target
The final step is to connect the 14-pin header side of the pod cable to the
target board via the debug interface. The 14-pin connector is keyed at
pin 3 on the pod cable to ensure that the cable sits correctly on the 14-pin
target emulation header. The target board should also have pin 3 keyed.
Never connect or disconnect a USB emulator JTAG header,
whether powered up or not, to/from a powered target.
The following procedures apply only to USB-based emulators.
Powering Up/Down an HPUSB or USB Emulator
To power up the USB-based emulator:
1. Apply power to target board.
2. Apply power to ICE.
3. Connect the USB cable between the ICE and the PC.
4. Invoke VisualDSP++.
To power down the USB-based emulator:
1. Shut down (exit) VisualDSP++.
2. Disconnect the USB cable between the ICE and the PC.

HPUSB, USB, and HPPCI Emulators User’s Guide 1-7
Getting Started
3. Power down the ICE.
4. Power down the target board.
If the emulator has an “Enable/Power” LED, this should be green
when power is applied. It should be amber when connected to a
session or the ICE Test utility is being used.

If the emulator has an “Enable” LED only, this should be amber
when connected to a session or while the ICE Test utility is being
used.

At all other times, this LED should be off.
For custom processor boards still in design, refer to Engineer-to-Engineer
Note, Analog Devices JTAG Emulation Technical Reference (EE-68),
available from the Analog Devices Web site. This document is a technical
reference for implementing the JTAG interface on your target.
The emulator hardware is ready to be used in conjunction with
VisualDSP++ to debug a processor target system.
VisualDSP++ Configurator
VisualDSP++ requires a description of your platform (JTAG chain). The
platform definition is necessary for VisualDSP++ to communicate with
the hardware through the emulator.
The VisualDSP++ Configurator’s ICE Test utility allows you to configure
and test your emulator hardware. ICE Test provides emulator detection,
JTAG I/O voltage selection, and JTAG frequency selection. Use the ICE
Test to test the target. If errors are encountered, they are reported imme-
diately and the test ends. Each error message recommends a solution to
the problem.

JTAG Frequency Selection
1-8 HPUSB, USB, and HPPCI Emulators User’s Guide
Refer to VisualDSP++ online Help for information about the
VisualDSP++ Configurator and the ICE Test utility.
JTAG Frequency Selection
High-Performance PCI-ICE and High-Performance USB-ICE emulators
support a JTAG clock operation up to 50 MHz. USB-ICE emulators
support a JTAG clock operation of 10 MHz.
There is a relationship between the JTAG frequency and the core clock
frequency of the processor. Typically, the core clock runs at a frequency
that is more than 2x the JTAG clock’s frequency. On newer Analog
Devices processors, the core clock is a variable that is sometimes set by
switches or by software.
If the core/JTAG clock relation is not followed, scan failures may
prevent the emulator from connecting to the processor.
Choosing the JTAG Frequency Selection from the Settings menu in
VisualDSP++ opens the JTAG Frequency Selection dialog box shown in
Figure 1-2 and Figure 1-3. The dialog box is used to change the rate at
which the JTAG Test Clock signal (TCK) runs.
Not all frequencies listed above appear for all processor families.
The displayed frequencies depend upon the processor family.
The tests listed in the Status box are run when you click the Test button
on the JTAG Frequency Selection dialog box. The blue arrow points to
the frequency currently being used. The arrow does not change after you
run the tests because pressing the Cancel button goes back to using the
frequency pointed to by the blue arrow. To use a different frequency,
select the appropriate frequency from the list and click Test. Clicking OK
uses the frequency that is highlighted and that has already been tested.
Table 1-1 lists and describes each of the available options.

HPPCI JTAG I/O Voltage Detection
1-10 HPUSB, USB, and HPPCI Emulators User’s Guide
If you encounter a problem launching VisualDSP++ at a certain
frequency, delete your debug session in VisualDSP++ and create a
new debug session. This will set TCK back to the default value of
10 MHz.
HPPCI JTAG I/O Voltage Detection
The mode of operation supported by the PCI emulator is dependent on
the connection method used for the 14-pin JTAG header on your target.
Figure 1-4 and Figure 1-5 show how the target JTAG header connects for
legacy and auto detection modes.
HPUSB/USB Legacy Mode
Legacy mode is used for older targets that do not provide a target VDDIO
input for automatic voltage detection by the emulator. In this mode, the
voltage at which the JTAG signals run is set manually through Visu-
alDSP++ via the VisualDSP++ Configurator utility. The configurator
utility provides a voltage selection setting when configuring the target.
Table 1-1. JTAG Frequency Selection Dialog Box Fields
Item Description
Select frequency (MHz) Selects the frequency to run TCK.
Status Updates status of the tests indicated within the test group. The test
status indicator can showa “running” icon, “not running” icon, “pass”
icon, or “fail” icon, depending on the test status.
Test Tests the selected frequency by running the tests in the Status group.
NOTE: If tests fail, you may have to shut down VisualDSP++ and
restart your session.
OK Saves the selected frequency. This should only be highlighted if all the
tests have passed.
Cancel Continues using the frequency pointed to by the blue arrow.
