Spectral Methods for Time-Domain Analysis of High-Speed Interconnects
The rapid increase in operating speed and density of modern integrated circuits has made a challenging problem of transmission line modeling. Its difficulty resides in the requirement to properly capture physical effects like reflection, dispersion, delay and attenuation, which cannot be neglected when broadband signals propagate along the interconnect. In addition, the presence of non-linear drivers and receivers call for efficient time-domain models. The lecture aims to present an overview of the state-of-the-art in interconnect modeling with a special attention to rational macromodels, state-space realization, model order reduction and parametric macromodels. Furthermore, the increased circuit density requires that designers make the proper trade-offs between conflicting design requirements using optimization techniques, to obtain the best possible performance. To this aim, efficient and accurate sensitivity information with respect to interconnect parameters are required by optimizers which employ powerful gradient based techniques and need the knowledge of sensitivities of the output responses. The lecture also aims to present sensitivity analysis technique in both frequency and time-domain with respect to either geometric or physical parameters.
