| 摘要 |
In some embodiments, a chip includes first and second scan chain segments each including registers and multiplexers to provide to the registers scan input signals during scan input periods and captured output signals during a capture periods. The chip also includes circuitry to provide first and second test clock signals to the registers of the first and second scan chain segments, respectively, wherein the second test clock signal is provided by a different signal path in the circuitry during the scan input periods than during the capture periods, and during the scan input periods the second test clock signal is skewed with respect to the first test clock signal. Other embodiments are described and claimed.
