What is Avrora?
Avrora, a research project of the
UCLA Compilers Group, is a set of simulation and analysis tools for
programs written for the AVR microcontroller produced by
Atmel
and the
Mica2 sensor nodes.
Avrora contains a flexible framework for simulating and analyzing
assembly programs, providing a clean Java API and infrastructure for
experimentation, profiling, and analysis.

Why Avrora?
Simulation is an important step in the development cycle of embedded
systems, allowing more detailed inspection of the dynamic execution
of microcontroller programs and diagnosis of software problems before
the software is deployed onto the target hardware. Avrora is a clean
and open implementation motivated by this need.
Avrora also provides a framework for program analysis,
allowing static checking of embedded software and an infrastructure
for future program analysis research. Avrora is flexible, providing
a Java API for developing analyses and removes the need to
build a large support structure to investigate program analysis.
What can Avrora do for me?
-
The provided simulator can test your
programs before they are deployed onto the hardware device
with cycle accurate execution times.
-
The monitoring infrastructure allows users to add online
monitoring of program behavior for better program understanding and optimization
opportunities.
-
The profiling utilities allow users to study their
program's behavior in simulation.
-
The instrumentation capabilities allow for detailed
observation of program behavior without disturbing the simulation, and without
modifying the simulator source code.
-
The GDB debugger hooks allow source-level debugging
and integrated development and testing.
-
The control flow graph tool can create a graphical representation
of your program's instructions that is useful for understanding how it is structured and
what the compiler does with your code.
-
The energy analysis tool can analyze energy consumption
and help to determine the battery life of your device.
-
The stack checker tool can be used to bound the maximum stack size
used by your program.
