Hi kirangu,

1. If you use top-down methodology partition flow in EDI system, type the following commands after defining the partition, place and trial routing:

deriveTimingBudget
savePartition

All necessary files will be saved including lib timing models for your partitions.

2. If you use bottom-top methodology, you need to create lib files manually. First of all when your block layout is finished and verified, you need to save your block LEF and project files using saveModel command. Then generate lib files for every analysis view typing next command:

do_extract_model -lib_name <libraryName> -view <analysisView> <libraryFilename>

Hope it was helpful.

Best regards,
Kuxx.

Hi Kuxx,

Thanks, it was helpful. I have a question here, during bottom up uproch, when our design is @ initial stage, lets say we have a dummy netlist or a black block netlist, how do we approach to get a budgeted .lib.

Thanks,
Kiran
