Re: [avr-gcc-list] How to debug AT90S8515/ATmega8515?

You can simulate the device in simulavr or simulavrxx.
With simulavrxx you are able to connect "outside" signals 
to your device or you could connect multiple avr chips together.
Each simulated core could be connected to a gdb instance. 
And gdb itself could be used from ddd so you have a nice GUI
for debugging on source level. It is also possible to
put a GUI on the simulavrxx to give you "mouse control" 
of your IO-pins or other hardware like serial(uart) or lcd and 
much more.

simulavrxx could be found on savannah.nongnu.org

I have no windows... sorry, can´t help with AvrStudio.
