Electronic components and systems with integrated self-test functionality

摘要

The present invention provides a first integrated sub-circuit having a defined interface and a defined fixed-hardware functionality, signal-connecting the first sub-circuit through the interface to exchange signals with and optionally energize the first sub-circuit to an electronic component comprising a second reconfigurable integrated sub-circuit comprising: and one or more terminals electrically coupling the electronic component to a periphery thereof. The second sub-circuit is configured as an interface circuit between the one or more terminals and the first sub-circuit. The second sub-circuit is configured to apply one or more input signals to the first circuit and, in response to the one or more input signals, apply one or more output signals received via the interface from the first sub-circuit to match one or more predetermined test criteria. by evaluating, further configured as a reconfigurable integrated test unit for testing the hardware functionality of the first sub-circuit. The present invention also relates to a system comprising two different components according to various embodiments of the electronic component.
