Z86K15 ICEBOX™ Emulator
Zilog
Setup and Installation
ST97KEY0100
2-5
NOTES:
1.
The emulation cable inductance and capacitance may affect the signals to and from the target
board, especially if the target board has low-current drivers, pull-ups, and pull-downs. We
recommend that you drive the XTAL pins of the device with the crystal oscillator on the
emulator with the J2 and J3 Jumpers removed.
2.
It may be necessary to reconfigure the emulation cable with the appropriate target pod for your
target device package.
Connecting a Logic Analyzer (Optional)
The logic analyzer can be connected as part of initial setup (or later as you continue working with your
parts).
Connect the logic analyzer to P4 Connector of the Emulator.
NOTE:
An ICEBOX emulator with a 100-pin connector requires a HP analyzer interface board (P/N
Z89C0000ZHP or ZINVASM0ZHP from Zilog).
Setting up the Oscillator and Option Jumpers
The oscillator and selected option jumpers are accessible from the top of the ICEBOX emulator (see
Figure 2-3). The option jumpers, which are accessible through the top cover, allow you to configure
things like whether the ICEBOX emulator provides power to your design on the V
cc
pin(s) of the em-
ulated device, and how the clock pin of the emulated device is connected. The clock for the emulated
device can be provided from an oscillator in the ICEBOX emulator or from a TTL-level clock on your
design. For electrical reasons, it cannot be provided from the oscillator on your design until you’re
done using the ICEBOX emulator and have done one of two things: 1) programmed an EPROM or
OTP device and installed it in your design, 2) installed a masked-ROM Z8 in your design.
NOTE:
Each Z86K15 ICEBOX is shipped with a 8 MHz oscillator to emulate 4 MHz system clock. If
you want other rates, remove the oscillator and install a different one, within the frequency
specifications of the device in use. (Zilog, however, does not guarantee such operation.)
