How to simulate an inertial delay in ModelSim?

I am attempting to simulate an inertial delay in ModelSim. The code compiles in Quartus II; however, the delays in my code are not showing up in the simlation. I assume it is a configuration issue, b...

I checked the design, screening all the Analysis and Synthesis settings..

Is .sdo the file containing the delay right? So I thought but no matter how many LCELL I introduce, from simulation in ModelSim I always get the same glitch in output (not delayed) as you can see from attached screenshot. I am compiling and simulating the .vo file within ModelSIm, is that correct, does it link automatically to the .sdo?

I am trying to simulate the delay introduced by LCELL chains in an already existing project, when I get a full understanding then I will be happy to consider more reliable solution, I guess with .sdc!

Thanks a lot for attention!
