Abstract :
The definition of Elmore´s delay is extended to include inductance effects. The pulse delay of nonmonotonic rising node voltage in a tree-structured interconnection can be described by this new definition. The double moment matching method is presented. Based upon this approach, a closed-form formula for computing the second order moment of any tree-structured interconnection is established. The approach enables the derivation of computationally simple and closed-form formulas of signal propagation delays of nonmonotonic rising node voltages in tree-structured interconnections. The authors´ results provide a new method for computing interconnection delay and reveal a critical link between net responses and net electrical properties. This formula set provides a tool to solve problems in the study of performance-driven-layout algorithms
