Features of SimulIDE
SimulIDE is a simple real time electronic circuit simulator. It is intended for hobbyists or students who want to learn and experiment with simple electronic circuits and microcontrollers. It supports PIC (Peripheral Interface Controller), AVR (Advanced Virtual RISC) and Arduino platforms. It is not an accurate simulator for circuit analysis. It aims to be fast, simple and easy to use. This means that it uses simple and not very accurate electronic models and has limited features. However, simplicity and ease of use are the key features of this simulator. You can create, simulate and interact with your circuits within minutes, just drag and drop components from the list, drop into the circuit, connect them and push power button to see how it works.
SimulIDE also features a code Editor and a debugger that allows you to write code in GcBasic, Arduino, PIC asm or AVR asm, compile and upload it to the microcontroller, set breakpoints, watch registers and variables, and step through the code. You can also use the serial port connection and serial monitor to communicate with the microcontroller and send or receive data. You can also use the oscilloscope and signal plotter to measure and visualize the signals in your circuit. You can also create and use subcircuits, which are groups of components and wires that can be saved and reused in other circuits. You can also use DIP/logic symbols to view the components as DIP packages or logic gates. You can also use circuit animation to view the components as animated images that change according to their state. You can also use basic shapes to add rectangles, circles, ellipses, lines, arrows, texts, etc. to your circuit.
How to install and run SimulIDE
SimulIDE is a free and open source software that you can download from its official website. It is available for Windows, Linux and Mac operating systems. It does not require installation, you just need to unzip the downloaded file and run the executable in the bin folder. For Windows users, the executable is SimulIDE.exe. For Linux users, the executable is SimulIDE.sh. For Mac users, the executable is SimulIDE.app.
How to create and simulate a simple circuit with SimulIDE
Creating and simulating a simple circuit with SimulIDE is very easy. You just need to follow these steps:
Open SimulIDE and click on the New Circuit button on the toolbar.
A new window will open with a blank circuit board. You can resize and zoom in or out of the board as needed.
On the left side of the window, you will see a list of components that you can use in your circuit. You can browse through the categories or use the search box to find the component you want.
Drag and drop the component from the list to the circuit board. You can rotate or flip the component by right clicking on it and choosing Rotate or Flip from the menu.
To connect the components with wires, click on one of the pins of a component and drag it to another pin of another component. A wire will be created automatically. You can change the color or thickness of the wire by right clicking on it and choosing Properties from the menu.
To power your circuit, you need to add a power source component, such as a battery or a DC source. Drag and drop it from the list to the circuit board and connect it to your circuit with wires.
To simulate your circuit, click on the Power button on the toolbar. The button will turn green and your circuit will start working. You can observe the voltage and current values on each component by hovering your mouse over them.
To stop the simulation, click on the Power button again. The button will turn red and your circuit will stop working.

To compile your code, click on Compile > Compile & Upload on the menu bar. This will compile your code and upload it to the microcontroller. You will see a message on the status bar indicating whether the compilation was successful or not. If there are any errors or warnings, you will see them on the output window.
To debug your code, click on Debug > Start Debugging on the menu bar. This will start the debugger and pause the simulation. You will see a yellow arrow pointing to the current line of code.
To set a breakpoint, click on the left margin of the code editor window next to the line of code where you want to pause the execution. A red dot will appear indicating the breakpoint.
To watch the registers and variables of the microcontroller, click on Debug > Watch on the menu bar. This will open the watch window where you can see the values of the registers and variables. You can also add or remove items from the watch list by right clicking on them and choosing Add Watch or Remove Watch from the menu.
To step through the code, you can use the buttons on the toolbar or the keyboard shortcuts. You can step over, step into, step out, run to cursor, run to next breakpoint, run to end, or stop debugging.
