Electronic circuit simulator.
Simple environment to run and debug firmware for AVR 8-bit microprocessors.
Able to run arduino firmware.
Internally this program uses the open source Simavr AVR Processor Simulator (https://github.com/buserror/simavr) and wraps all its functions in a GUI shell. Setups for firmware debugging scenarios can be created dynamically. Able to run 16MHz MCU with decent set of external parts in real time. In particular this can be used for development of CNC firmware...
