Abstract: Systems and methods for testing integrated circuits (ICs) are provided. In this regard, a representative method involves an IC having a first pad configured as a signal interface for components external to the IC, the first pad having a first receiver configured to receive an input signal from a component external to the IC. The method comprises: electrically interconnecting automated test equipment (ATE) with the IC; providing at least one stimulus such that the IC detects a presence of a signal short between the first pad and the second pad; and receiving information corresponding to the signal short.

Abstract: A circuit and method for determining operating speed of a clock associated with an integrated circuit (IC), comprises an IC logic element, a scan chain, and a calibration circuit comprising a first plurality of flip-flops and a combinational delay line. The calibration circuit operates in a functional test mode and in a scan test mode to determine a clock signal delay between the functional test mode and the scan test mode.

Abstract: Tools, systems and/or methods for use in a test process of a circuit device. Such tools, systems and/or methods may provide for identifying respective parent and branch portions of a scan chain of a circuit device, the scan chain having at least one scan input and one or more scan outputs and a plurality of scan cells; and creating a model of the scan chain, including creating a dummy cell chain which includes a branch portion of the scan chain and has one or more dummy cells disposed therein connected between the branch portion and the scan input.

Abstract: A preferred integrated circuit (IC) includes a first pad electrically communicating with at least a portion of the IC. The first pad includes a first driver and a first receiver, with the first driver being configured to provide a first pad output signal to a component external to the IC, and the first receiver being configured to receive a first pad input signal from a component external to the IC. The first receiver also is configured to provide, to a component internal to the IC, a first receiver digital output signal in response to the first pad input signal. A first test circuit also is provided that is internal to the IC. The first test circuit is adapted to provide information corresponding to the driver clock-to-q time of the first pad. Systems, methods and computer-readable media also are provided.
