Sensitivity analysis of multiconductor transmission lines and optimizationfor high-speed interconnect circuit design

Sensitivity analysis of multiconductor transmission lines is derived from a new, all-purpose multi-conductor transmission line model in both frequency domain and time domain. Computer implementation of this new model as well as the sensitivity analysis has been completed. It enables efficient, accur ate simulations of interconnect circuit responses as well as sensitivity an alysis with respect to both electrical and physical transmission line param eters. By applying sensitivity analysis to high-speed interconnect circuit design, design variables are optimized to achieve simultaneous minimization of crosstalk, delays and reflections at desired nodes in the circuit witho ut violating any indispensable design rules. Numerical examples are present ed to demonstrate the validity of the proposed sensitivity analysis and ill ustrate its application to the optimization of high-speed interconnect circ uit design.
