CAD in new areas of the package and interconnect design space

Passive interconnection networks are important for three reasons. First, they represent an increasing percentage of the cycle time as the active devices are "scaled". Second, they contribute to di/dt, coupled, and reflected noise. Third, higher clock frequencies are making the interconnection medium a more effective radiator, especially in the 30 MHz to 1 GHz range where limits have been established by regulatory agencies such as the FCC. Approaches to understanding these phenomena will be highlighted.
