L. Sheng et J. Wu, A note on "A tight lower bound on the number of channels required for deadlock-free wormhole routing", IEEE COMPUT, 49(9), 2000, pp. 1005-1005
In [1], Libeskind-Hadas provided a tight lower bound on the number of chann
els required by a broad class of deadlock-free wormhole routing algorithms.
In this short note. we show a simpler proof of the tight lower bound.
