You can directly modify register values (e.g., port pins or ADC inputs) during runtime to test how your software handles different scenarios.

Compare the simulator to (PICkit 4, Snap). Let me know which of these would help you most! MPLAB® Mindi™ Analog Simulator - Microchip Technology

Track code execution flow and data transfers.

Developing embedded applications for Microchip PIC microcontrollers traditionally required physical hardware, debugger probes, and circuit boards. Today, powerful software simulation tools integrated into the development cycle allow engineers to write, debug, and test code entirely on a PC, saving time and hardware costs.

Mastering Microchip PIC Development: A Guide to Software Simulation

A PIC software simulator acts as a virtual microcontroller on your computer. It mimics the behavior of the PIC’s internal architecture—including CPU registers, memory (RAM/Flash), timers, and input/output ports—without needing the physical chip. Key Features of MPLAB X Simulator
