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
