The digital storage element also comprises a slave transparent latch coupled to the master transparent latch, the slave transparent latch comprising dedicated functional data and scan data output ports. While operating in a scan mode, a first clock signal is used by the slave transparent latch and a second clock signal is used by the master transparent latch, wherein the first and second clock signals are non-overlapping.

    摘要: A digital storage element (e.g., a flip-flop or a latch) includes a master transparent latch that receives functional data from a data input port and scan data from a scan input port and a slave transparent latch coupled to the master transparent latch. The slave transparent latch includes dedicated functional data and scan data output ports. The digital storage element operates in a functional mode and in a scan mode. While in the scan mode, a first clock signal is used by the slave transparent latch and a second clock signal is used by the master transparent latch. The first and second clock signals are non-overlapping and, as such, avoid the digital storage element from creating hold violations.

    摘要: A digital storage element comprises a master transparent latch that receives functional data from a data input port and scan data from a scan input port and a slave transparent latch coupled to the master transparent latch. The slave transparent latch comprises dedicated functional data and scan data output ports. The master and slave transparent latches have opposite transparent polarities when in a functional mode and have the same polarities (e.g., positive level sense) when in a scan mode. The transparent polarity of a transparent latch defines the state of a clock to that latch for which the transparent latch is transparent.
