Simplicity, speed and ease of use are the key features of this simulator.
You can create, simulate and interact with your circuits within minutes, just drag components from the list, drop into the circuit, connect them and push the “power button” to see how it works.

Simulation speed is one of the most relevant characteristics of this simulator.
It has been deeply optimized to achieve excellent speeds and low cpu usage.

SimulIDE also features a code Editor and Debugger for Arduino, GcBasic, PIC asm, AVR asm and others. It is possible to write, compile and do basic debugging with breakpoints, watch registers and global variables.
