StepTest ​

Test that validates step response behavior by connecting a step signal to a terminator.

This component creates a test setup for validating the Step block by connecting its output to a Terminator. The Step block generates a signal that starts at the offset value and jumps by the height value at the start_time. The test case verifies that the signal properly transitions from the initial offset value to the final value (offset + height).

Usage ​

StepTest()

Behavior ​

signal.y(t)=terminator.u(t)signal.y(t)=ifelse(t≥signal.start_time,signal.height+signal.offset,signal.offset)
