扫描触发器的选择采用BALLAST算法。
BALLAST algorithm is used to select the best scan flip-flops.
该多工器提供选择该扫描输入端或该数据输入端任一者作为该触发器输入端。
The multiplexer allows selection of either the scan input or the data input for presentation at the input of the flip-flop.
该扫描输入端与该触发器输入端之间的延迟大大地大于该数据输入端与该触发器输入端之间的信号传播延迟。
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.
该延时元件在位于该扫描输入端与该触发器输入端之间的信号路径上，并于该扫描输入端与该触发器输入端间提供信号传播延迟。
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.
