I wish to shift a waveform by 0.2 seconds to the left and the value before origin should be zero. Can anyone help me how to do this in simulink? Variable time delay is not what I want to do. I should have the entire waveform in complete form and shifted to the left by 0.2 seconds.

What is the waveform generated from? Some of the standard Source blocks let you control the phase which could left-shift your signal.

Or, if your waveform comes from MATLAB workspace data, you could just subtract 0.2 from the entire time vector when you import it to the Simulink model.
