  As compared to DRC rules, DFM rules are a list of selected recommended rules
which aim to improve the design margins for better manufacturability. In
GLOBALFOUNDRIES, we use DFM scoring methodology as an effective technique to
analyze design quality in terms of manufacturability. Physical design engineers
can perform our Manufacturability Check Deck (MCD) to asset their design
quality during the sign-off stage. In the past, Synopsys users have to convert
their design though milkyway database to GDSII format and execute the
verification through the third party EDA tools. This method is costly and
time-consuming for our Synopsys users. Today, we propose a new and easy-to-use
integrated flow which leverages on the ICV engine to provide DFM scoring and
in-design fixing techniques. The new methodology address DFM violations early
in the design flow and achieve DFM compliance design during sign-off phase.
