    • A scan flip-flop circuit including a data input, a scan input, a data output, a flip-flop, a multiplexer and a delay element is provided. The multiplexer allows selection of either the scan input or the data input for presentation at the input of the flip-flop. The flip-flop provides an output signal at the output of the scan flip-flop. The delay element is in a signal path between the scan input and the input of the flip-flop, and provides a signal propagation delay between the scan input and the input of the flip-flop. The delay between the scan input and the input of the flip-flop is substantially larger than the signal propagation delay between the data input and the input of the flip-flop. The delay in the scan path reduces the need for external buffers to avoid hold-time violations during scan testing of integrated circuits.
    • 提供了包括数据输入,扫描输入,数据输出,触发器,多路复用器和延迟元件的扫描触发器电路。 复用器允许选择扫描输入或数据输入以在触发器的输入处呈现。 触发器在扫描触发器的输出端提供输出信号。 延迟元件在扫描输入和触发器的输入之间的信号路径中,并且在扫描输入和触发器的输入之间提供信号传播延迟。 扫描输入和触发器的输入之间的延迟显着大于数据输入和触发器输入之间的信号传播延迟。 扫描路径的延迟减少了外部缓冲器的需要,以避免集成电路扫描测试期间的保持时间违规。
