The Lauterbach product TRACE32-PowerTrace/NEXUS
supports the NEXUS standard class 1 to 3. The hardware
module for the NEXUS debugger is universal and allows
to interface different target processors by simply changing
the NEXUS adapter and starting a new
software.

Hardware Concept
TRACE32-PowerTrace/NEXUS
The NEXUS support is based on the
universal hardware module TRACE32-
PowerTrace. The connection to the
NEXUS interface on the target is done
by a CPU specific NEXUS adapter.
TRACE32-PowerTrace includes a USB
and Ethernet interface.

Software Concept Debugger
Symbolic Debugging
A hierarchical symbol database
enables structured symbolic debug-
ging. Symbol names can be used to
show single program addresses, mod-
ule names and memory classes. The
disassembler can use the symbols for
labels and/or operands. Demangling
for C++ signatures is supported.

High-Level Language Debugging
TRACE32 can directly load the output
of all standard compilers for C, C++,
JAVA, Pascal, Modula2, PEARL and
ADA from most compiler vendors. Pro-
gram display and debugging can be
done in assembler, high-level or in a
mixture of both. It is possible to con-
struct both assembler and high-level
windows on the screen simultaneously.
All variable types specific to the high-
level language can be displayed and
modified. Addresses can be absolute,
relative or line number based.
Real-time update
Real-time update of memory and vari-
ables is possible while the CPU is run-
ning.
Debugging
The debugger uses the following
breakpoint implementations to stop the
program execution at a certain instruc-
tion:
J
Umlimited Code Breakpoints in
FLASH areas
J
a limited number of onchip
breakpoints for code in ROM/
FLASH
J
unlimited number of software
breakpoints for code in RAM
