  • Inversion of scan clock for scan cells
    Patent number: 7613967
    Abstract: A device includes a scan circuit including a scan chain. The scan chain includes a first plurality of scan cells that receive a first scan clock signal in a first clock domain. A second plurality of scan cells receives a second scan clock signal in a second clock domain. A scan clock source generates the first scan clock signal and the second scan clock signal, and selectively inverts the first scan clock signal and the second scan clock signal based on an operating mode of the first plurality of scan cells and the second plurality of scan cells, respective flip-flop arrangements of the first clock domain and the second clock domain.

  • Inversion of scan clock for scan cells
    Patent number: 7447961
    Abstract: In one embodiment, an apparatus comprises a scan circuit including at least a first and a second clock domain and a scan chain having a first plurality of scan cells positioned in the first clock domain and a second plurality of scan cells positioned in the second clock domain. A scan clock source, coupled to the scan chain, generates a first scan clock signal to the first plurality of scan cells and a second scan clock signal to the second plurality of scan cells. The first and the second clock signals have an inverted relationship.
