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 Atmeland 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.
