simavr - lean and mean AVR simulator
simavr [OPTION]... [FILE]
Execute AVR firmware, produce VCD waveform files and/or run a debugging session. Specify simulation parameters directly in the emulated code using .elf section or by passing command line arguments. For more complex virtual circuitry prototyping and simulation see AVR simulator development examples and documentation.
FILE is an elf or ihex formatted executable firmware, assuming filename extension .hex for ihex files. --list-cores List all supported AVR cores and exit -m CORE, --mcu CORE Run simulation on CORE -f FREQ, --freq FREQ Set core speed in HZ -t, --trace Run full scale decoder trace -ti VECTOR Add traces for IRQ vector -g, --gdb Listen for gdb connection on port 1234 -ff Load next .hex file as flash -ee Load next .hex file as eeprom -i INPUT, --input INPUT Read input signals from a .vcd file -v Raise verbosity level (can be passed more than once) -h, --help Display usage message and exit
AVR GDB DEBUGGING Run the AVR firmware simulation: simavr -g -m atmega328p -f 16000000 firmware.elf start avr-gdb and optionally enable tui for better source code readability: avr-gdb (gdb) tui enable load the elf formatted firmware and connect to the running simulation: (gdb) file firmware.elf (gdb) target remote :1234 set a break point and go ahead, debug: (gdb) break main (gdb) continue (gdb) next (gdb) next
