MPLAB ? REAL ICE ? IN-CIRCUIT
EMULATOR USER ’S GUIDE
Chapter 2. Operation
2.1
INTRODUCTION
A simplified description of how the MPLAB REAL ICE in-circuit emulator system works
is provided here. It is intended to provide enough information so a target board can be
designed that is compatible with the emulator for both emulation and programming
operations. The basic theory of in-circuit emulation and programming is described so
that problems, if encountered, are quickly resolved.

MPLAB REAL ICE IN-CIRCUIT EMULATOR VS. MPLAB ICE 2000/4000
EMULATORS
The MPLAB REAL ICE in-circuit emulator system is a next generation In-Circuit
Emulator (ICE) system. It differs from classical in-circuit emulator systems (e.g.,
MPLAB ICE 2000/4000) in a single, but important way: the production device and
emulation device are the same. This means that the actual device/emulated device
differences are all but eliminated. For example, speed bottlenecks caused by bringing
internal busses off-chip and using external memories on classical emulator systems
are eliminated by using the actual device for emulation.
Another significant benefit is that there is no time lag from when the device is released
to when an emulator module to support the device can be released. If a header board
is required, it can be developed to coincide with the device release, or lag it by a small
amount, which is a great improvement over the longer processor module development
times.
MPLAB REAL ICE IN-CIRCUIT EMULATOR VS. MPLAB ICD 2 DEBUGGER
The MPLAB REAL ICE in-circuit emulator system is similar to the MPLAB ICD 2
in-circuit debugger system, but surpasses it in speed and functionality. Even with
standard communication, the MPLAB REAL ICE in-circuit emulator is faster than the
MPLAB ICD 2. With the high-speed communication option, it is much faster. Also, in
addition to basic debug functions, the MPLAB REAL ICE in-circuit emulator
incorporates “emulation” functions, such as trace.
