rect()

Rectangular pulse function

Syntax
rect(x0, tc, td)

Name	Description	Range	Type	Required
x0	program time or freq variable	[0, ∞)	real	yes
tc	center time	(-∞, ∞)	real	yes
td	duration	(-∞, ∞)	real	yes

Examples

This example assumes that a transient simulation is performed using:
StartTime = 0, StopTime = 400ps, MaxTimeStep = 1ps
This expression produces a rectangular pulse:
value = rect(time, 100ps, 100ps)

Notes/Equations

The function rect() creates a rectangular pulse of variable Time centered at time tc with duration td. It can be used to create a current or voltage rectangular pulse using the ItUserDef or VtUserDef time domain sources. Alternately it can be used in other expressions.
The output is calculated as follows:
For td > 0:

For td< 0:
