Product Overview

PICsim

Description: PICsim is an open-source circuit simulator and microcontroller emulator that allows users to test and debug PIC microcontroller code on their computer. It provides a GUI workspace for designing circuits and writing/uploading code to a virtual PIC chip.

simavr

Description: simavr is an open-source AVR simulator for Linux/Windows/macOS. It can emulate popular AVR microcontrollers like ATmega128, simulating the behavior of the microcontroller so developers can test firmware without hardware.
