APPENDIX B BLOCK DIAGRAM
(2) Driver module block
The driver module block consists of the following six:
(a) I/O emulation board
(b) Emulation board
(c) Mother bus interface
(d) Event trace board
(e) Performance board
(f) Control interface
Each of these is described next.
(a) I/O emulation board
♦
I/O emulation
Emulates the target device.
♦
Target interface
Interfaces the target system via the emulation probe.
♦
Clock block
The clock block selects the clock to be supplied to the evachip under direction by the supervisor.
<1> The internal clock of the IE is used.
<2> The user clock is used (supplied from the emulation probe or a user clock is mounted).
(b) Emulation board
♦
Emulation CPU
Provided with the CPU emulation function of the target device and special functions of the IE-784000-
R.
♦
Latchup warning block
Turns off power to the emulation CPU, peripheral CMOS devices of the emulation CPU, and TTL at the
stage preceding to the CMOS devices if a latchup occurs in the emulation CPU, peripheral CMOS devices,
or TTL.
♦
Program execution detection block
Detects program execution at a set address.
♦
3-V emulation/5-V emulation selector block
Allows emulation in accordance with the supply voltage of the target.
