One of the strongest features of SimulIDE is the built-in toolchain integration:
SimulIDE is an open-source circuit simulator with embedded microcontroller support, including STM32 (ARM Cortex-M) models. This paper evaluates SimulIDE’s capability to simulate STM32 devices in a “full” context — including GPIO, timers, interrupts, ADC, and communication peripherals (UART, SPI, I²C). We compare simulation accuracy against physical hardware and against other simulators (QEMU, Proteus). Results show that SimulIDE offers acceptable accuracy for education and prototyping, with limitations in timing precision and advanced peripheral support.
The user drags an STM32 component onto the canvas. External components (crystals, power sources, LEDs) are wired to the pins.
Goal: STM32 reads a temperature sensor (e.g., analog TMP36 or I2C digital sensor), displays on a small OLED, timestamps entries, and saves periodic logs to an SD card (SPI) with a roll-over file policy.

Getting Started with SimulIDE
To begin simulating STM32 projects, you first need to set up the software environment:
Download and Install: Obtain the latest version of SimulIDE compatible with your OS. It is typically distributed as a compressed folder; simply extract it and run the executable.
Required Tools: For STM32 development, it is highly recommended to use STM32CubeIDE for writing code, configuring peripherals, and generating the necessary firmware files (usually in .elf or .hex format). Simulating an STM32 Project
The simulation process in SimulIDE involves bridging your compiled code with the virtual hardware. 1. Circuit Design
In the SimulIDE workspace, you can drag and drop components from the left-hand panel. Locate the Micros group to find supported STM32 models. You can build a complete circuit by adding LEDs, switches, or sensors and connecting them to the MCU pins. 2. Loading Firmware Once your code is compiled in STM32CubeIDE:
Right-click the STM32 microcontroller in the SimulIDE workspace.
Select Load Firmware and browse for your compiled .hex or .elf file. One of the strongest features of SimulIDE is
Enable Reload hex at simulation start in the properties panel to ensure the simulation always uses your latest code after every re-compile. 3. Monitoring and Debugging
SimulIDE offers several tools to inspect the "internals" of your running STM32:
MCU Monitor: View RAM, registers, variables, and the program counter in real-time.
Serial Monitor: If your project uses UART communication, you can open a serial monitor to send and receive text or numeric data.
Properties Panel: Adjust the microcontroller frequency and other configuration bits without needing an external crystal. Key Features for STM32 Developers
High-Speed Simulation: SimulIDE is optimized for speed, allowing for smooth real-time interaction with digital circuits.
Analog & Digital Integration: The simulator handles both modes simultaneously, allowing for the simulation of complex effects like impedance and logic thresholds.

For SimulIDE and STM32 enthusiasts looking for a "full" guide or community post, it is important to note that while SimulIDE is a powerful, real-time circuit simulator, its native support for the full range of STM32 microcontrollers is still evolving compared to older families like AVR or PIC.
However, you can achieve a "full" workflow by combining STM32CubeIDE for code development with SimulIDE for hardware simulation. Below is a structured "post-style" guide to setting up this environment. 🚀 Getting Started with STM32 in SimulIDE
To successfully simulate an STM32 project, you need to bridge the gap between your code (firmware) and the virtual hardware.
Step 1: Write and Compile CodeUse STM32CubeIDE to write your application. Before compiling, ensure you configure the project to generate a .hex or .bin file, as these are the formats SimulIDE requires to "load" the firmware onto the virtual chip.
Step 2: Set Up the CircuitOpen SimulIDE and drag an STM32-compatible MCU from the component panel. If a specific STM32 model isn't listed, check the SimulIDE Forum for user-created custom components or subcircuits.
Step 3: Load FirmwareRight-click the microcontroller in SimulIDE and select "Load firmware". Navigate to your project's output folder (usually /Debug or /Release in STM32CubeIDE) and select your compiled file.
Step 4: Configure the ClockDon't forget to match the frequency! Right-click the MCU, go to Properties, and set the Frequency to match what you configured in your code (e.g., 8MHz or 72MHz for a BluePill). 🛠️ Key Tips for Success
Real-Time Monitoring: Use the Monitor tool in SimulIDE to watch registers and RAM in real-time while your simulation is running.
External Peripherals: SimulIDE excels at simulating the "outside world." You can easily connect LEDs, displays, and sensors to your STM32 pins to test interaction without risking real hardware.
Community Resources: For specific "how-to" examples and community-shared circuits, the SimulIDE Knowledge Base is the best place to find ready-to-run files. 💡 Why use SimulIDE for STM32? SimulIDE – Circuit Simulator
