    Abstract: An apparatus and method are provided for testing integrated circuits. An integrated circuit arrangement is provided having first and second dice. Each die has circuitry for diagnostic testing in response to a diagnostic test signal. The circuitry further defines an input for receiving the diagnostic test signal and an output for transmitting results of the diagnostic testing for each of the dice. Interconnecting circuitry between the dice transmits the diagnostic test signal transmitted to the first die to the second die before the diagnostic testing is completed in the first die.

    Abstract: A method of testing the performance of a combinational logic circuit is described. In contrast to a structural test which verifies the operation of the combinational logic circuitry, a performance test allows the performance of a combinational logic circuit to be tested by determining the accuracy of a set of outputs resulting from a change in input bits to the combinational logic circuit. Thus, it is possible to monitor more closely performance aspects, such as the maximum delay from input to output of a combination logic circuit.

    Abstract: A scan latch is described which comprises a capture half-latch, a release half-latch and an update half-latch. The capture half-latch has an input terminal connected to receive an input signal, a control terminal connected to a clock signal, and an output terminal. The release half-latch and update half latch each have an input terminal fixedly connected to the output terminal of the capture half latch. The release half-latch also has a control terminal connected to a clock signal and an scan output terminal. The update half-latch also has a control terminal connected to a clock signal and a data output terminal. The combination of the capture half-latch and one of the update half-latch and the release half-latch acts as a full-latch. The combination of these half-latches allows for simplified circuitry for testing integrated circuits. Clock signals provided to the half-latches can be different clock signals, and their timing can be individually controlled. This scan latch comprising half-latches can be used in place of any full-latch where a scan test is to be carried out and where a functional data output should not change while scan data is being shifted in or out. Furthermore, a scan latch according to this invention is also able to carry out a performance test to test the timing of logic circuitry. A method of using the scan latch to carry out a structural test of a circuit is also described.

    Abstract: A half-latch for a scan latch is described. The half-latch has an input terminal for receiving an input signal a first control terminal for receiving a clock signal and an output terminal. When enabled, the half-latch adopts a data transfer state in which it transmits a signal from its input terminal to its output terminal. Alternatively, the half-latch can adopt a data holding state in which a signal is stored on the output terminal, these states being selected in dependence on the state of the clock signal. The half-latch described herein has a second control terminal which receives the control signal to selectively disable the half-latch. This allows a common clock signal to be used when a scan latch is constructed using these half-latches.
