It's worth noting that Micro Magic's design tools are likely what allowed them to claim these numbers. Some of the claims they make about their software are pretty impressive, but it mainly boils down to intelligent placing/routing techniques that mirror fully custom hand-made silicon designs but are actually designed by the computer: http://www.micromagic.com/datasheets/PDFs/DPC_3page_Layout.p...

It seems like their design workflow is ahead of the rest of the field.
