Abstract
According to one embodiment, a self-test system integrated on a chip is provided, the chip including a functional logic module for performing a selected application. The self-test system includes a primary interface a primary interface to the functional logic module, the primary interface configured to interface with a primary device, an input interface protocol generator for generating a pattern to be inserted into the primary interface and a secondary interface to the functional logic module, the secondary interface configured to interface with a secondary device. The system also includes an emulator engine coupled to the secondary interface, the emulator engine for testing a function of the functional logic module based on the inserted patterns, the function being configured to communicate with a secondary device coupled to the secondary interface, wherein the emulator engine tests the function when no secondary device is coupled to the chip.
