SimulIDE is a lightweight, real-time circuit simulator that has increasingly become a viable alternative to heavyweight tools like Proteus for STM32 development. While it lacks the massive library of some competitors, its primary advantage is the ability to simulate, compile, and debug code directly within a single, open-source environment.  Core STM32 Features in SimulIDE 

MCU Support: It primarily supports popular ARM Cortex-M microcontrollers like the STM32F103 (commonly known as the Blue Pill).

Integrated Compiler: You can configure SimulIDE to use external toolchains (like arm-none-eabi-gcc) to compile your C/C++ code directly from the built-in editor.

Live Debugging: It features a monitor that allows you to watch registers, SRAM, ROM, and program memory in real-time as the simulation runs.

Mixed-Signal Simulation: Unlike some purely digital simulators, SimulIDE runs everything in analog mode. This means it can simulate realistic electrical effects like fan-in/fan-out and configurable impedance on logic pins.  Simulating a Full Adder (Logic vs. MCU) 

If you are looking to build a "Full" system, you can approach it in two ways within the software: 

Hardware Logic: Use the built-in "Arithmetic" components to drag and drop a pre-configured Full Adder module. You can then connect fixed voltage sources as inputs (0 or 1) and LEDs with resistors to visualize the Sum and Carry Out.

MCU Logic (STM32): You can write code to perform the same logic on an STM32 chip. By toggling GPIO pins based on input states, you can replicate complex logic gates within the microcontroller.  Setting Up Your Workflow  To get a "full" solid piece working, follow these steps:  simulide stm32 full

Component Selection: Find STM32 models under the Micro category in the component list.

Code Integration: Use the SimulIDE Knowledge Base to link your STM32CubeIDE projects. You can load .hex or .bin files directly into the simulated MCU.

Scripted Components: If you need a specific peripheral not in the library, you can create scripted components using simple scripts to define custom behavior without needing full hardware emulation. 

These tutorials demonstrate how to set up STM32 simulations and logic circuits within SimulIDE and similar environments: 6 min

#include "stm32f10x.h"
int main() 
  GPIO_InitTypeDef gpio_InitStructure;
// Enable GPIOA clock
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
// Configure GPIO Pin 5 as output
  gpio_InitStructure.GPIO_Pin = GPIO_Pin_5;
  gpio_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
  gpio_InitStructure.GPIO_Speed = GPIO_Speed_2MHz;
  GPIO_Init(GPIOA, &gpio_InitStructure);
while (1) 
    // Toggle LED
    GPIO_WriteBit(GPIOA, GPIO_Pin_5, Bit_ RESET);
    delay_ms(500);
    GPIO_WriteBit(GPIOA, GPIO_Pin_5, Bit_SET);
    delay_ms(500);
void delay_ms(uint32_t ms) 
  uint32_t i;
  for (i = 0; i < ms * 1000; i++);

While SimulIDE has a built-in editor, many developers use external tools like STM32CubeIDE for complex development and then load the compiled firmware into SimulIDE for testing. 82. Simulate STM32 in Proteus using STM32CubeIDE
