Optimizing the Integration of DFM and P&R
DFM tools can help shorten design iterations and improve yield, but they are typically not well-integrated with P&R (place and route) environments. Back-annotation of DFM (design for manufacturing) changes requires time-consuming database conversions from GDS/OASIS (graphic design system/open artwork system interchange standard) to DEF (design exchange format). To support full integration with P&R tools, design verification and optimization tools must be able to read and write DEF files, either through direct read/write capabilities or by using database conversion processes. A new solution introduces a direct write DEF capability for fast, accurate back-annotation of fill, via, and net objects to P&R applications.
