This property only affects pulse waveforms, and together with Scallop Pulse Width it determines the pulse's shape. For the Pulse and Rounded Pulse waveforms, it sets how quickly the pulse rises and falls. For the Triangular Pulse waveform, it skews the triangle. For the Ramp Pulse waveform, it rotates the ramp. Slew is normalized to the range zero to one. For more information, see Slew.
