The µVision Debugger simulates up to 4GB of memory. Memory areas can be mapped for read, write, or code execution access. The µVision Simulator traps and reports any illegal memory access.

The Simulator supports many integrated peripherals of various microcontrollers. When selecting a microcontroller from the Device Database, µVision configures the instruction set and the peripherals. The menu Peripherals displays on-chip peripheral components and allows changing aspects of each peripheral using dialog controls.


  • The Simulator is cycle accurate and, where possible, accurately simulates instructions and on-chip peripheral timing.
  • Developers can provide external stimulus using Debug Functions.
  • Refer to Setup the Project for details about selecting a device.
