simavr is a lean, hackable Atmel AVR microcontroller simulator written in C, loading ELF/HEX firmware directly and emulating peripherals like UART, SPI, I2C, timers, and ADC. It includes GDB support and VCD waveform output for debugging embedded firmware without hardware.
Use cases
- simulate avr firmware without hardware
- debug arduino code with gdb
- test embedded firmware in ci
- generate vcd waveforms from avr simulation
- prototype avr project quickly
- emulate atmega328 firmware on linux
When to choose
- you develop AVR/Arduino firmware and want fast, scriptable simulation
- you need GDB debugging or VCD tracing of emulated microcontroller code
- you want a small, hackable simulator core to embed in your own tooling
When to avoid
- you need simulation of non-AVR architectures like ARM or RISC-V
- you require cycle-accurate timing for hardware validation
- you want a polished GUI-based IDE experience
