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 environments. Previously, back-annotation of DFM changes required time-consuming database conversions from GDS/OASIS to DEF format. Direct write DEF capability now enables fast, accurate back-annotation of fill, via, and net objects to P&R applications.
