Optimizing the integration of DFM and P&R
DFM optimization requires EDA tools to read P&R data in DEF format
The Calibre nmPlatform direct read DEF and direct write DEF functionalities enable core Calibre applications to read P&R design data in DEF format using rule deck operations. Direct read DEF enables LEF/DEF object and property mapping to Calibre layers, while the direct write DEF capability enables Calibre applications to write incremental or full design DEF format data directly from Calibre operations. Together, they can be used to build tightly integrated flows for P&R engineers, and enable fast, accurate back-annotation of fill, via, and net objects to P&R applications.
