step()

Step function

Syntax
step(time)

Name	Description	Range	Type	Required
t	program time variable	(-∞, ∞)	integer, real	yes

Examples

This example assumes that a transient simulation is performed using:
StartTime = 0, StopTime = 2ns, MaxTimeStep = 50ps
This expression produces a step pulse with value = 0.5 at time = 0, 1 at time > 0:
value = step(time - tau)
where tau = 1.0ns

Notes/Equations

This expression creates a step function. It can be used to create a current or voltage step wave using the ItUserDef or VtUserDef time domain sources.
The output is calculated as follows:
