Abstract

In an embodiment, a method for performing scan testing includes: generating first and second scan clock signals; providing the first and second scan clock signals to first and second scan chains, respectively, where the first and second scan clock signals includes respective first shift pulses when a scan enable signal is asserted, and respective first capture pulses when the scan enable signal is deasserted, where the first shift pulse of the first and second scan clock signals correspond to a first clock pulse of a first clock signal, where the first capture pulse of the first scan clock signal corresponds to a second clock pulse of the first clock signal, and where the first capture pulse of the second scan clock signal corresponds to a first clock pulse of a second clock signal different from the first clock signal.
