UiMOR - UC Riverside Model Order Reduction Tool for post-layout wideband interconnect modeling

In this paper, we introduce a new model order reduction tool, UiMOR - UC Riverside Model Order Reduction Tool. UiMOR fills the gap between parasitic extraction and post-layout simulation to improve the efficiency of VLSI circuit validation. UiMOR is a stand-alone circuit complexity reduction tool. It can perform accurate reduction for wideband frequency range with negligible loss of accuracy and is well suited for analog/mixed-signal/memory designs. It also works well for traditional delay and noise calculations in digital circuits. It works seamlessly with the existing digital and analog design tools that use the standard SPICE format interface. We then present some numerical comparison results with an existing industry tool, Ultrasim. UiMOR is now available for free download from UC Riverside.
