What is Cone Resynthesis for Efficient ECO Implementation about?
This document describes a novel "cone resynthesis" approach to implementing large functional changes through ECO without requiring full block resynthesis. Traditional ECO methods try to minimize changes to the layout, which can degrade timing, whereas this method replaces logic cones from a new synthesized netlist. It generates ECO scripts to remove existing cones and add new ones. Specialized techniques address placement, routing, and timing convergence challenges from large changes. This method was used t
