How To achieve pulse supply voltage with four different levels of voltage

Hi Everyone
I am new to using cadence. I want to have a pulse supply voltage with four different levels of voltage (Let's say V0 V1 V2 V3). each voltage level stands for a specified period (let's say T0 T2 T2 T3) with the transition between any two levels having Fall time =TF and Rise time=TR.

So in general we should have 10 parameters (V0 V1 V2 V3 T0 T1 T2 T3 TF TR)
Any help or suggestion,

It may be done in Verilog A, but I just start learning Verilog A. any code will be helpful.
Is there a possibility to get this supply done using the Instance sources from AnalogLib
