Two-pole approximation for interconnect design and optimization

Firstly, an approach to find two approximate poles for capturing the system behaviour of interconnect network is presented. Secondly, two parameters, the damping ratio and natural undamped frequency, are expressed as function s of the two poles. These two parameters are used to define an objective fu nction and constraints, which form a constrained multivariable nonlinear op timization problem. The optimization problem is solved using a gradient pro jection method. One major advantage of our approach is the ability to expli citly control the maximum overshoots at the observation points.
