在读工艺库的文档时,看到有这么一个glitchless multiplexer cell,描述如下:
The MXGL2 cell is a 2-to-1 glitchless multiplexer, based on a NAND2-NAND3
implementation. The state of the select input (S0) determines which data input (A, B) is presented to the output (Y). The output (Y) is represented by the logic equation:Y = (S0 o A) + (S0 o B)
我看好些库都有这个cell,不知道是怎么实现的,真的能完全无毛刺吗?能直接用来切换时钟吗?
