I guess what you were asking is to import SDF to Cadence Virtuoso DFII database ? And you have imported Verilog gate level netlist into the DFII.
Actually you don't need to "import SDF" to be "DFII database" . SDF file is a standard text, you can directly backannotate SDF text file to your Verilog gate level netlist during ncelab stage either in command mode or GUI mode.
Here is what you need to do .. For example , you have raw SDF file "my_sdf.txt"
1. run ncsdfc to generat compiled SDF file ncsdfc my_sdf.txt ---> generat my_sdf.txt.X which is compiled SDF file
2. Prepar SDF command file say MY_SDF_CMD.txt , for example COMPILED_SDF_FILE = "PATH_TO_YOUR_SDF_FILE/my_sdf.txt.X" ; SCOPE = top.I0.I1 ; ----- This means that your verilog gate level block is top.I0.I1 in top level design context .
....
3. In AMS-ADE or AMS-HED GUI In ncelab options -> SDF command field , please fill path_to_your_sdf_command_file/MY_SDF_CMD.txt
So that SDF will backannotate to the verilog gate level block ..
Hope this helps .. Zhong
