Specifying SDF files for simulation

ModelSim supports SDF versions 1.0 through 3.0. The simulator's built-in SDF annotator automatically adjusts to the version of the file. Use the following vsim command-line options to specify the SDF files, the desired timing values, and their associated design instances:

-sdfmin [<instance>=]<filename>
-sdftyp [<instance>=]<filename>
-sdfmax [<instance>=]<filename> 

Any number of SDF files can be applied to any instance in the design by specifying one of the above options for each file. Use -sdfmin to select minimum, -sdftyp to select typical, and sdfmax to select maximum timing values from the SDF file.
