Sensitivity Based Link Insertion for Variation Tolerant Clock Network Synthesis
Clock distribution is one of the key limiting factors in any high speed, sub-100nm VLSI design. Unwanted clock skews, caused by variation effects like manufacturing variations, po...

Optimal sizing of high-speed clock networks based on distributed RC and lossy transmission line models
We have proposed an e cient measure to reduce the clock skew by assigning the clock network with variable branch widths. This measure has long been used for \H" clock tree. T...
