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, but I have not found any tutorials on how to set Quartus and ModelSim up to account for intertial delays. The software is Quartus II 12.0 WE and ModelSim ASE 10d.
A simple case of what I'd like to simulate is:
A <= B or C after 5 ns;
During the simulation, the output A receives the "OR" of B and C, but the change is instant. There is no 5 ns delay.
Any How To's are appreciated.

Are you simulating in Quartus or Modelsim. Quartus will ignore "after" statement. Modelsim should not. There is no setting to enable or disable delay in modelsim as it is part of simulation modelling as far as I know. Check you are not overwriting your assignment. Also check your observation.
