Abstract
A system for accurately determining Elmore delays in DCVSL structures is disclosed. The system uses circuit simulation to determine models for Elmore delays through devices within specific circuit structures. The circuit structures include DCVSL circuits to accurately model performance of devices with such a structure. The system also determines discharge characteristics for DCVSL circuits using simulation. In order to determine Elmore delays, the system analyzes a circuit representation to locate DCVSL structures. The discharge characteristics and models are used to determine Elmore delays for each structure located.
