Implementing enhanced performance dynamic evaluation circuit by combining precharge and delayed keeper

摘要

A method and circuit for implementing enhanced performance dynamic evaluation, and a design structure on which the subject circuit resides are provided. The dynamic evaluation circuit includes a combined precharge and keeper device connected to a precharge node. The dynamic evaluation circuit includes control logic providing a control input to the combined precharge and keeper device. The combined precharge and keeper device responsive to the control input holds the precharge node precharged when the precharge node is not discharged early in an evaluate cycle.
