2.2 Non-intrusive Inspection and Debugging

Simics has powerful built-in inspection and debugging facilities. These include:

• Inspecting registers, memory, and hardware state.
• Modifying register and memory contents, and hardware state.
• Setting (and triggering) breakpoints and watchpoints.
• Powerful scripting support for all of this.

Because these are implemented in the simulator, no debugging software needs to be on the target at all. As a result, the debugging machinery is completely invisible to the target (and thus to any software running on it).
