I would like to hear about users that are successfully using allegro DFA and have integrated their contract manufactures rule set into this process and how the integration was accomplished.
All replies are appreciated
DFA_DLG is the standalone program of the DFA Spreadsheet in Allegro. At the symbol level you would add a property called DFA_DEV_CLASS to define the DFA Group or Classification for the symbol. These classification are loaded in the DFA Spreadsheet then you can define clearances between the different classification of symbols.
It is really a lot to explain so I would recommend checking out the "Best Practices: Working with Real-Time DFA Analysis" in the Cadence documentation to give you a good idea how it all works. You can also access a PDF version of the Best Practices by browsing to it in Windows Explorer by entering %CDSROOT%\doc\algroDFA.
Good luck,Mike Catrambone
