ICEBOX

Setup and Installation UM002202-1001

c. Attach the voltmeter lead to either pin 1 or 3 on the J1 jumper and

ground.

d. Power the ICEBOX with the target device disconnected.

e. Turn the voltage adjuster’s screw until the voltmeter’s read-out

matches the target device’s voltage.

Failure to match the target devices voltage with the ICE chip’s

voltage could result in damage to the ICEBOX, target device, or

ICE chip.

Power the ICEBOX

If anything unusual (such as an unexpected sound and/or smell) occurs

when turning on the power supply, turn off the power supply and check

the setting for the J1 jumper. See Set Power Jumper on page 12. If the

power supply allows voltage adjustment, adjust it again to +5 V. The

power supply output may measure less than +5 V because of the load of

the ICEBOX. If your power supply has a current meter, ensure that the

ICEBOX is drawing within the rated current.

After power-up, press the RESET button to reset the ICE chip. (Pressing

the RESET button avoids bus contention on the I/O lines.) If the ICEBOX

is not powering your design through the V

pin, turn on the power

supply of the design.

If your design already has a power supply, do not power your

design from the ICEBOX V

pin.

When powering down, follow the procedure described below:

1. Halt emulation.

2. In ZDS select Reset from the Build or Debug Menu.

3. Power down the target application board (if using its own power

supply).

4. Power down the ICEBOX.
