Duplicate cell names across multiple IP in an SoC can result in unexpected layout results at the full-chip level, larger file sizes, and the inability to run layout verification tools efficiently in hierarchical mode. The Calibre DESIGNrev tool provides a simple, efficient, automated solution for identifying, renaming, and reporting these cell name conflicts. The outcome is a clear and consistent design process, straightforward chip assembly, a clean and meaningful design hierarchy, faster EDA tool runtimes, and faster time to tapeout.
