Step Signal (G Dataflow)

Last Modified: January 12, 2018

Generates the point-by-point value of a step signal.



A Boolean that specifies the initialization of the internal state of the node.

True Initializes the internal state of the node by returning the output at time t = 0.
False Does not initialize the internal state of the node.

Default: False



Amplitude of the step signal.

Default: 1



Lower limit of the step signal.

Default: 0


step time

Simulation time, in seconds, at which the output changes from offset to offset + amplitude.

Default: 0



Loop-cycle time or interval, in seconds, at which this node is called.

dt must be greater than zero.


step output

Point-by-point value of the step signal.

Algorithm Definition for the Step Signal

The following equations define the step signal:

y = { u if t < step time u + a if t step time


  • y is the step signal
  • u is the lower limit of the step signal
  • a is the amplitude of the step signal
  • t is the current simulation time
