Delay Minimization for Zero-Skew Routing
Delay minimization methods are proposed for zero-skew routings.
A delay-time estimation formula is derived, which can be used as
an objective function to be minimized in zero-skew routing algorithms.
Moreover, the optimum wire width is formulated. Experimental results
show that our methods with a clustering-based algorithm achieve 50%
reduction of the delay time on benchmark data with 3000 pins.
