Why doesn't the output data toggle when running a gate-level simulation (.sdf)?

In order to view output data that toggles at a high frequency in a third-party simulation tool, enable the transport switches in the simulation tool. The following switches must be enabled: ...

Along the same lines, if you are performing gate level timing simulations with Cadence NCsim simulator, the equivalent switches to transport cell and interconnect delays are:

-PULSE_R and -PULSE_INT_R

e.g.

ncelab work.<my design> -TIMESCALE 1ps/1ps -PULSE_R 0 -PULSE_INT_R
