摘要
We propose a hierarchical interconnection network with two-phase bufferless resonant clock distribution, which mixes the advantages of mesh and tree architectures.The problems of skew reduction and variation-tolerance in the mixed interconnection network are studied through a pipelined multiplier under a TSMC 65 nm standard CMOS process.The post-simulation results show that the hierarchical architecture reduces more than 75% and 65%of clock skew compared with pure mesh and pure H-tree networks,respectively.The maximum skew in the proposed clock distribution is less than 7 ps under imbalanced loading and PVT variations,which is no more than 1%of the clock cycle of about 760 ps.
