Abstract
Integrated circuitry comprises target circuitry and test circuitry. The target circuitry uses a clock signal to transfer a target signal within the integrated circuitry. The test circuitry samples the target signal at a selected time from a plurality of possible times within a clock cycle of the clock signal. The test circuitry samples the target signal in response to a test signal indicating the selected time.
