Timing Simulation error in Quartus prime 16.1

I wanted to run timing simulation for a multiplier i designed. However after successful functional simulation, the tool is giving an error while running timing simulation i.e:# ** Error (suppressible): (vsim-SDF-3196) Failed to find SDF file "Karatsuba_vhd.sdo". 

# vsim -novopt -c -t 1ps -sdfmax Karatsuba_vhd_vec_tst/i1=Karatsuba_vhd.sdo -L cyclonev -L altera -L altera_mf -L 220model -L sgate -L altera_lnsim work.Karatsuba_vhd_vec_tst  

# Error loading design

Please let me know what can be done.

From the Error message it looks like you are missing the .sdo file. 

 

What device are you targeting ? 

 

Gate-level timing simulation is supported only for the Arria II GX/GZ,Cyclone IV, MAX 

II, MAX V, and Stratix IV device families.. Use Timing Analyzer static timing analysis 

rather than gate-level timing simulation.
