Simulavr: A simulator for the Atmel AVR family of microcontrollers.
|
|
|
|
This program is still under development and is not ready for production
|
|
use. The simulator is stable enough for rudimentary debugging work in
|
|
conjuction with a gdb-5.2 (see README.gdb).
|
|
|
|
At this early stage of development, when simulavr enters a failure mode, it
|
|
will print an error message and abort, thus generating a core file. This is
|
|
actually quite useful, since you can examine the core file and see what caused
|
|
simulavr to get confused. This is similar to what happens when a program seg
|
|
faults and dumps core, but the error message should at least tell you where to
|
|
start looking since it gives the file name and line number where the error
|
|
message was generated. As of version 0.0.14, I haven't seen simulavr abort in
|
|
quite some time. Take that with a grain of salt. :)
|
|
|
|
I've only been testing this with the at90s8515 since that's the only device I
|
|
have right now to compare with.
|
|
|
|
I am hoping to support all AVR devices, but am not going to work on the TINY's
|
|
and MEGA's until I get all the features of the at90s* devices working, and
|
|
have solid gdb support. If someone else would like to contribute code for TINY
|
|
or MEGA support, that would be greatly appreciated.
|
|
|
|
To build the simulator, you need to use gcc for now. There is some gcc
|
|
specific code in the source. I'm only doing this for now since it makes
|
|
debugging a little bit easier. I'll gladly accept porting feedback if someone
|
|
wishes to work on that front. I'm currently only developing using RedHat 7.2.
|
|
|
|
Some preliminary porting has been done on NetBSD and FreeBSD.
|
|
|
|
To build my test asm and C files, you need to have gcc and binutils build for
|
|
avr and installed in your path.
|
|
|
|
See the INSTALL file for more information on building and installing the
|
|
simulator.

|
There is the beginnings of documentation in the doc/ directory. The build
|
|
system should automatically build the info, postscript and html formats of the
|
|
documentation. If for some reason you have trouble building the documentation
|
|
from the texinfo source, check the simulavr web site. I hope to keep the
|
|
latest versions of the documenation there.
