Discrete Variables and Events

Discrete Event Modeling

Simplify mathematical model of the system by assuming that certain variables can change values instantaneously and discontinuously at specific points in time.

Triggered Delay Component

This example shows how to implement a triggered delay component.

Enabled Component

This example shows how to implement a component similar to a Simulink® enabled subsystem.

Mode Charts

Mode Chart Modeling

Model components characterized by discrete set of distinct operating modes.

Switch with Hysteresis

This example shows how to model a component by using mode charts and enumerations.
