Live Demo: ECOS 1.0: A Metal-Only ECO Synthesizer

Abstract

To ease the time-to-market pressure and save the photomask cost, metal-only ECO realizes the last-minute design changes by revising the photomasks of metal layers only. This task is challenging because the pre-injected spare cells are limited in number and in cell types. We develop a metal-only ECO synthesizer, named ECOS, that automates the incremental design changes without sacrificing timing and routability. Via the live demonstration, visitors can experience the superior performance of ECOS.
