Passivity Preserving Model Order Reduction Using the Reduce Norm Method
Modeling and design of on-chip interconnect, the interconnection between the components
is becoming the fundamental roadblock in achieving high-speed integrated circuits. The scaling
of interconnect in nanometer regime had shifted the paradime from device-dominated to
interconnect-dominated design methodology. Driven by the expanding complexity of on-chip
interconnects, a passivity preserving model order reduction (MOR) is essential for designing and
estimating the performance for reliable operation of the integrated circuit. In this work, we developed
a new frequency selective reduce norm spectral zero (RNSZ) projection method, which dynamically
selects interpolation points using spectral zeros of the system. The proposed reduce-norm scheme can
guarantee stability and passivity, while creating the reduced models, which are fairly accurate across
selected narrow range of frequencies. The reduced order results indicate preservation of passivity
and greater accuracy than the other model order reduction methods.
