You get and SDF file from your place and route tool.

Start DC, setup your libraries, read in the verilog netlist file, setup your wireload models (or even the original constraints you used), then you should be able to write out a SDF file. But then, as Petter mentioned, it is better to get SDF output from layout extraction. Output from DC is not very accurate (since wire delay is modeled by wire load model).
