Abstract: Various embodiments include nested emulation for a source application and source emulator. Duplicate source ISA libraries redirect the source emulator library calls to a target library, thereby forcing the native emulator through proper emulation channels between first and second ISAs.

Abstract: A method for emulating and debugging a microcontroller is described. In one embodiment, an event thread is executed on an emulator that operates in lock-step with the microcontroller. Event information is sampled at selected points. Trace information is also recorded at the selected points. As such, the event information and trace information are effectively pre-filtered.

Instead, this task is essentially done automatically, helping the designer and reducing the probability of error. Furthermore, because only selected event and trace information is recorded, the resources of the in-circuit emulator system are not taxed.
