DESIGNING AN EMULATOR-COMPATIBLE
PROCESSOR BOARD (TARGET)
The Analog Devices family of emulators are tools that every sys-
tem developer needs in order to test and debug hardware and
software systems. Analog Devices has supplied an IEEE 1149.1
JTAG Test Access Port (TAP) on each JTAG processor. The
emulator uses the TAP to access the internal features of the pro-
cessor, allowing the developer to load code, set breakpoints,
observe variables, observe memory, and examine registers. The
processor must be halted to send data and commands, but once
an operation has been completed by the emulator, the processor
system is set running at full speed with no impact on
system timing.
To use these emulators, the target board must include a header
that connects the processor’s JTAG port to the emulator.
For details on target board design issues including mechanical
layout, single processor connections, multiprocessor scan
chains, signal buffering, signal termination, and emulator pod
logic, see (EE-68) Analog Devices JTAG Emulation Technical
use site search on “EE-68.” This document is updated regularly
to keep pace with improvements to emulator support.

RELATED SIGNAL CHAINS
A signal chain is a series of signal-conditioning electronic com-
ponents that receive input (data acquired from sampling either
real-time phenomena or from stored data) in tandem, with the
output of one portion of the chain supplying input to the next.
Signal chains are often used in signal processing applications to
gather and process data or to apply system controls based on
analysis of real-time phenomena. For more information about
this term and related topics, see the "signal chain" entry in
website.
Analog Devices eases signal processing system development by
providing signal processing components that are designed to
work together well. A tool for viewing relationships between
