delay measurement with modelsim

Hi,

I wanna measure delay of a ripple carry adder from modelsim simulation.program works fine.I can see the output waveforms also.but i can't find any delay between inputs and output even with zoom view.

    Delay isn't modelled in a functional (RTL) simulation. You need to perform a gate-level simulation to see it.
