The MPLAB® X IDE includes a powerful discrete-event simulator for:

  • PIC® Microcontroller (MCU) Families
  • dsPIC® Digital Signal Controller (DSC) Families

The simulator is integrated into MPLAB X IDE (integrated development environment). The simulator debugging tool is designed to model the operation of Microchip Technology's MCU and DSC devices to assist in debugging software for these devices.


MPLAB X Simulator allows you to:

  • Modify object code and immediately re-execute it
  • Inject external stimuli to the simulated processor - stimulus is the simulation of hardware signals
  • Set pin and register values at pre-specified intervals
  • Trace the execution of the object code
  • Code coverage to detect “dead” code areas
  • Extract data for validation

Not all simulator features are supported. See the MPLAB X IDE Release Notes for more on supported and unsupported features.
