Transient simulation in Cadance
A transient simulation simulates the circuit's conditions over time. You seem to have no component in your circuit which introduces a time varying voltage.

Use a vpulse source instead of the vdc (V17), fill in it's properties so that it will step the supply voltage. Simulate that, then check that the supply voltage has the transient step that you want to simulate. If that is OK, look at the voltages inside the circuit.
