HPUSB, USB, and HPPCI Emulators User’s Guide 2-1 
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...

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...

HPUSB, USB, and HPPCI Emulators User’s Guide 2-3  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...

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...

HPUSB, USB, and HPPCI Emulators User’s Guide 2-5  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...
