Regulatory Compliance
The USB- and PCI-based emulators are designed to be used solely in a
laboratory environment. The emulators are not intended for use as a con-
sumer end product or as a portion of a consumer end product. The
emulator board is an open system design which does not include a
shielded enclosure and therefore may cause interference to other electrical
devices in close proximity. This board should not be used in or near any
medical equipment or RF devices.
The USB- and PCI-based emulators have been certified to comply with
the essential requirements of the European EMC directive 2004/108/EC
and therefore carries the “CE” mark.
The USB- and PCI-based emulators have been appended to Analog
Devices, Inc. EMC Technical File (EMC TF) referenced DSPTOOLS1,

The USB- and PCI-based emulators contain ESD (electrostatic discharge)
sensitive devices. Electrostatic charges readily accumulate on the human
body and equipment and can discharge without detection. Permanent
damage may occur on devices subjected to high-energy discharges. Proper
ESD precautions are recommended to avoid performance degradation or
loss of functionality. Store unused emulators in the protective shipping
package.

If the emulator has an “Enable/Power” LED, the power LED lights
green when power is applied. The power LED lights amber when
connected to a session or when the ICE Test utility is used.
If the emulator has an “Enable” LED only, the LED lights amber
HPUSB, USB, and HPPCI Emulators User’s Guide 1-7
Getting Started
when connected to a session or when the ICE Test utility is used.
At all other times, the LED should be off.
For custom processor boards still in design, refer to the Engineer-to-Engi-
neer 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.
Now the emulator hardware is ready to be used in conjunction with CCES
or VisualDSP++ to debug a processor target system. See “Configurator
Software”.
Configurator Software
CrossCore Embedded Studio and VisualDSP++ development software
require a description of your platform (JTAG chain). The platform defini-
tion is necessary for the software to communicate with the hardware
through the emulator.
The VisualDSP++ and CCES include the target configurator utility to
configure and test your emulator hardware. The target configurator pro-
vides emulator detection, JTAG I/O voltage selection, and JTAG
frequency selection. Use the ICE Test (part of the target configurator) to
test the target. If any errors are encountered, the errors are reported imme-
diately and the test ends. Each error message recommends a solution to
the problem.
Refer to the online help for information about “target configurator”,
“JTAG frequency”, and “ICE test”.
JTAG Frequency Selection
1-8 HPUSB, USB, and HPPCI Emulators User’s Guide
JTAG Frequency Selection
USB-ICE emulators, high-performance PCI-ICE, and high-performance
USB-ICE emulators support a JTAG clock operation up to 50 MHz.
Not all frequencies listed above are supported for all processor fam-
ilies. The displayed frequencies depend upon the processor family.
There is a relationship between the JTAG frequency and core clock fre-
quency 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 sometimes is set by switches or
software.
If the core/JTAG clock relation is not followed, scan failures can
prevent the emulator from connecting to the processor.
Use the JTAG Frequency Selection dialog box to test and change the rate
at which the JTAG Test Clock signal (TCK) runs. To access the dialog
box:
• CrossCore Embedded Studio users choose Target > Settings >
JTAG Frequency Selection after launching a debug configuration.
• VisualDSP++ users choose Settings > JTAG Frequency Selection
after creating a debug session.
JTAG Frequency Selection
1-10 HPUSB, USB, and HPPCI Emulators User’s Guide
The tests listed in the Status box are run when you click Test in the JTAG
Frequency Selection dialog box. The blue arrow points to the current fre-
quency. The arrow does not change after you run the tests because Cancel
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 . Click OK to use the frequency that is highlighted and tested
already.
Table 1-1 describes the JTAG Frequency Selection dialog box.
If you encounter a problem launching the CCES or VisualDSP++
at a certain frequency, delete your debug configuration/session and
create a new debug configuration/session. This sets TCK back to
the default value.
Table 1-1. JTAG Frequency Selection Dialog Box
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 show a “running” icon, “not running” icon, “pass”
icon, or “fail” icon, depending on the test status.
Te s t Tests the selected frequency by running the tests in the Status group.
NOTE: If tests fail, you may have to shut down the IDE 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.
HPUSB, USB, and HPPCI Emulators User’s Guide 1-11
Getting Started
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.
Table 1-2 shows 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 the Config-
urator utility. The configurator utility provides a voltage selection setting
when configuring the target.
HPUSB-ICE and USB-ICE emulators do not support auto voltage
detection mode.

HPPCI-ICE Legacy/Auto Detection Mode
The factory default for the pod shown in Figure 1-4 is legacy mode. For
more information about available modes, refer to “Auto Detection Mode”
on page 1-14.
In order to modify the factory default setting, remove the four screws on
the bottom of the plastic enclosure. When opening the case, first remove
the top of the enclosure with the top facing up. This must be done to
ensure that the four light pipes used for the LEDs are not damaged. The
default pod setting is shown in Figure 1-5. To determine whether the
default setting of your HPPCI-ICE needs to be modified, refer to “Legacy
Mode (Factory Default Setting)”.
Figure 1-4. HPPCI-ICE Pod
HPUSB, USB, and HPPCI Emulators User’s Guide 1-13
Getting Started
Legacy Mode (Factory Default Setting)
Legacy mode is used for older targets that do not support voltages less
than 3.3V and do not provide an IOVDD input for automatic voltage
detection by the pod. Consequently, the emulator in legacy mode is used
for all previously designed 3.3V and 5V target boards. The HPPCI-ICE is
3.3V compliant and 5.0V tolerant in this mode and accepts both 3.3V
and 5.0V signals but only drives 3.3V CMOS level signals. In legacy
mode, the LED labeled 3.3/5V is lit.
The emulator is set to Legacy mode before leaving the factory. The switch
must be set in the manner shown in Figure 1-6 to verify that the emulator
is in legacy mode, or to change the emulator to legacy mode.
Figure 1-5. Default Switch Setting for HPPCI-ICE Pod
HPPCI JTAG I/O Voltage Detection
1-14 HPUSB, USB, and HPPCI Emulators User’s Guide
Auto Detection Mode
Auto detection mode is recommended for all newly designed target
boards. This mode supports 1.8V, 2.5V, 3.3V, and 5V target boards.
PCI-based emulators are 1.8V, 2.5V, and 3.3V-compliant in auto
detection mode. This means that the emulator can accept 1.8V, 2.5V, and
3.3V signals and can also drive the respective 1.8V, 2.5V, and 3.3V
CMOS level signals. The emulator is also 5V tolerant. Consequently, the
emulator accepts 5V signals and drives 3.3V signals to the target.
In auto detection mode, the emulator samples the target VDDIO signal
(pin 5 on the JTAG header) and drives the JTAG signals from the emula-
tor at the sampled voltage. The respective 1.8V, 2.5V, or 3.3/5V LED also
lights up to indicate the voltage at which the JTAG signals are driven.
The emulator is set to legacy mode before leaving the factory. The switch
must be set in the manner shown in Figure 1-7 to verify that the emulator
Figure 1-6. Legacy Switch Setting for HPPCI-ICE Pod

is in auto detection mode, or to change the emulator to auto detection
mode.

2 HARDWARE DESCRIPTION
This chapter describes the hardware design of the USB- and PCI-based
emulators.
LEDs
This section describes the following LEDs:
•“HPUSB-ICE/USB-ICE LEDs”
•“HPPCI-ICE LEDs” on page 2-2
•“Pod LEDs” on page 2-2
•“Board LEDs” on page 2-4
HPUSB-ICE/USB-ICE LEDs
Four LEDs are located on the enclosure:
• 1.8V LED – Signifies that the ICE drives all signals at 1.8V
compliant levels.
• 2.5V LED – Signifies that the ICE drives all signals at 2.5V
compliant levels.
LEDs
2-2 HPUSB, USB, and HPPCI Emulators User’s Guide
• 3.3/5V LED – Signifies that the ICE drives all signals at 3.3V
compliant levels.
• ENABLE – This LED is amber when the debugger is enabled. This
means that the emulator is driving the JTAG signals, and the con-
nector must not remove or plug onto a target when the light is
amber. When the LED is green, the JTAG signals are not being
driven, and it is safe to connect to a target. The green LED indi-
cates that the board is powered up but not in emulation mode.
HPPCI-ICE LEDs
Four LEDs are located on the pod enclosure (Figure 2-1), and five LEDs
are located on the daughter board (Figure 2-2).
Pod LEDs
Figure 2-1. Pod LEDs

Hardware Description
• 1.8V LED – In auto detection mode, this LED signifies that a
target VDDIO of 1.8V has been detected on the JTAG header
(pin 5) on the processor target board, and the HPPCI-ICE drives
all signals at 1.8V compliant levels.
• 2.5V LED – In auto detection mode, this LED signifies that a
target VDDIO of 2.5V has been detected on the JTAG header
(pin 5) on the processor target board, and the HPPCI-ICE drives
all signals at 2.5V compliant levels.
• 3.3/5V LED – In auto detection mode, this LED signifies that a
target VDDIO of 3.3V or 5V has been detected on the JTAG
header (pin 5) on the processor target board, and the HPPCI-ICE
drives all signals at 3.3V compliant levels. In legacy mode, this
LED is powered automatically, and pin 5 of the JTAG header on
the target board is not used to detect the target VDDIO voltage.
• ENABLE – This LED is turned on when a CrossCore Embedded
Studio (CCES) or VisualDSP++ debug session is running. This
LED shuts off every time the session is closed. When this LED is
off, it signifies all outputs of the pod logic connected to the target
have been three-stated. Three-stating the outputs of the pod when
the IDE is inactive prevents the target processor from entering an
unknown state during the target power up sequencing.

Board LEDs
• VCC – This LED signifies that the board is receiving 5V power. If
this LED is not active, the HPPCI-ICE does not function properly.
• 3V – This LED signifies that the board is receiving 3.3V power. If
this LED is not active, the HPPCI-ICE does not function properly.
• FPGA[1:0] – These two LEDs are used for factory purposes only.
• DONE – This LED is activated when a a CrossCore Embedded
Studio or VisualDSP++ debug session is started. The LED should
remain active even after the respective session has been terminated.
The LED shuts off and re-activates at the beginning of every new
session.

Hardware Description
Custom Processor Boards
When designing a custom processor board using Analog Devices
processors and DSPs, special care must be taken to ensure that the JTAG
interface is designed and laid out correctly. If the board is not designed
correctly, communication via the JTAG port may not work. Another side
effect may be that the interface works, but you are not able to run at the
highest possible JTAG clock frequency. The JTAG clock frequency is
dependant on the particular Analog Devices processor, as well as the delay
characteristics of the custom processor board.
To ensure that the custom board’s JTAG interface is designed and laid out
correctly, refer to Engineer-to-Engineer Note, Analog Devices JTAG Emu-
lation 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.
HPPCI-ICE
The HPPCI-ICE consists of a daughter board and a pod cable. The system
is compliant with revision 2.2 of the PCI specification and plugs into
5V-only motherboards. It uses only the 5 volts from the PC’s PCI slot.
The pod cable consists of a small PCB that has a multi-conductor cable
soldered at each end. The multi-conductor cable is constructed with indi-
vidual coaxial cables that are encapsulated by shield ground. The PCB in
the pod is fully enclosed in a copper-sprayed plastic enclosure. The
multi-conductor cables and copper spray reduce system noise and electro-
magnetic interference.
