Abstract

Capacitative coupling will become a dominant problemdue to increased parasitic capacitance between adjacentwires and faster signal switching rates. The couplingproblem is more acute for domino logic circuits since anirreversible gate output transition can result. We presenta method to analyze domino circuits for susceptibility tocrosstalk failures from a layout-extracted netlist. Specifi-cally, sites in the circuit that may fail due to crosstalk areidentified. In addition, failure sites are partitioned intotwo categories (faults or design errors) based on theirlikelihood of occurrence in the context of manufacturingvariations. The method has been implemented and appliedto a dual-rail dominoWallace tree circuit with littleloss in accuracy, resulting in a 37X speedup over a fullanalysis using Hspice.
