An apparatus and method is described herein for providing a test, validation, and debug architecture. At a target or base level, hardware hooks (Design for Test or DFx) are designed into and integrated with silicon parts. A controller may provide abstracted access to such hooks, such as through an abstraction layer that abstracts low level details of the hardware DFx. In addition, the abstraction layer through an interface, such as APIs, provides services, routines, and data structures to higher-level software/presentation layers, which are able to collect test data for validation and debug of a unit/platform under test. Moreover, the architecture potentially provides tiered (multiple levels of) secure access to the test architecture. Additionally, physical access to the test architecture for a platform may be simplified through use of a unified, bi-directional test access port, while also potentially allowing remote access to perform remote test and debug of a part/platform under test. In essence, a complete test architecture stack is described herein for test, validation, and debug of electronic parts, devices, and platforms.

Test, validation, and debug architecture

Debugging a device, including a device having power-saving features, may include observing and controlling power state transitions.
