Abstract: An integrated circuit with enhanced testability provides a normal-operation mode of operation with an observability function matching that used in a test-drive mode. Specifically, in both normal-operation mode and test-drive mode, captured signal vectors from captured-signal nodes are stored in a signal-vector queue. Thus, the local storage of signal vectors during test-drive mode does not represent a deviation from normal operation that could otherwise impair test validity. Moreover, since captured-signal vectors are stored during normal-operation mode, they are available for readout when normal operation is halted. These captured-normal-signal vectors reflect normal operation without any distortion due to testing—so data validity is optimal. Drive-signal vectors can be stored in the queue, which can be a dual-ported RAM, during a test-setup mode, and readout to driven-signal nodes in test-drive mode.
