Dear Ramesh,

The standard command to simulate a model in Modelsim is "vsim". The key "-sdftyp" allows you to use an sdf file for simulation. However, I am not sure if you can actually simulate an sdf file. It rather a timing for a model in Verilog format, for example.

# -sdftyp[@] [=]

# Annotate VITAL or Verilog with typical

# timing from , scaled by

In the TCL file, write the below:

eval vsim -sdftyp /uut1=SDF_File_Name.sdf Test_Bench_Module_Name

Please feel free to ask any question if you need.
