Simulating and Debugging STM32 Microcontrollers Title: A Comprehensive Analysis of SimulIDE for STM32

| Feature | Support Level | |---------|----------------| | GPIO (Input/Output) | ✅ Full | | Timers (Basic) | ✅ Full | | PWM | ✅ Full | | USART | ✅ Full | | I2C | ⚠️ Partial (no multi-master) | | SPI | ⚠️ Partial (no DMA) | | CAN Bus | ❌ Not implemented | | USB Peripheral | ❌ Not implemented | | DMA | ❌ Not implemented | | Floating-point unit (FPU) | ⚠️ Experimental | | Debugging (Step into C) | ✅ Via GDB bridge (advanced) | Run the simulation (green play button)

Setting Up Breakpoints

  1. Run the simulation (green play button). It auto-starts the GDB server on port 1234.
  2. Open a terminal and connect GDB manually: 
    arm-none-eabi-gdb firmware.elf
(gdb) target remote localhost:1234
(gdb) break main
(gdb) continue
  3. In SimulIDE, you can now step through code while watching circuit voltages change in real-time.

“Full-System Simulation of STM32 Microcontrollers Using SimulIDE: Performance, Limitations, and Embedded Workflow Integration”

Features a built-in code editor and debugger for languages like Arduino, GcBasic, PIC asm, and AVR asm. Performance: Optimized for high simulation speeds and low CPU usage. Advanced Monitoring:

| Limitation | Solution | | :--- | :--- | | No USB peripheral simulation | Use UART bridge to a virtual COM port instead. | | Limited Floating Point Unit (FPU) speed | Compile with -mfloat-abi=soft for simulation; keep hard for hardware. | | Cannot simulate multiple MCUs on one bus | Split into multiple SimulIDE instances or use QEMU-system mode. | | No RTOS-aware debugging (FreeRTOS) | Use info threads in the external GDB client manually. |
