Precise, data-backed diagram creator

Use high-fidelity timelines and state-line notations to see how your embedded hardware and software interact.

Track state changes with precision

Use timing diagrams to track exactly how long a component stays in a specific state, making it easy to spot race conditions or synchronization bottlenecks before they hit production.

Leverage specialized scales

Use specialized notation to represent value lifelines and state-transition timelines. Shape libraries within Lucidchart make it simple to track multiple lifelines simultaneously to identify synchronization issues.

What is a UML timing diagram?

A timing diagram is a specific behavioral modeling diagram that focuses on timing constraints. While similar to a sequence diagram, it focuses on the duration of events rather than just their order. By mapping time along the horizontal axis, you can identify latency issues, synchronization gaps, and areas where your process can be optimized for better performance.

How to create a UML timing diagram

Identify the lifelines and participants

Identify which objects or components in your system require precise timing and synchronization.

Define possible states

List the different conditions or “values” each object can inhabit.

Define the time axis

Draw a horizontal axis at the bottom of your diagram to represent the passage of time. You can use absolute units, such as milliseconds, or relative segments to show the order of operations.

Map out the state transitions

Draw horizontal lines to show the current state of an object. When a change occurs, use a vertical step to move to the new level. Continue the new horizontal line to represent the exact duration the object remains in that state.

Add events and messages

Draw arrows between lifelines to illustrate the triggers for state changes. Use these messages to show how a signal from one component causes another component to shift states.

Apply constraints and observations

Define the timing rules for your system. Use brackets to mark constraints and observations to verify if your system meets its performance requirements.

Frequently asked questions about UML diagrams

Can I build a UML diagram using markup?

Yes. First, you will need to enable the UML sequence diagram shape library. Then, Lucidchart provides a UML sequence markup feature that auto-generates a sequence diagram based on the text you provide.

How can I change the formatting of a UML diagram?

You can add styling and formatting to your UML diagram using the Properties bar at the top of the Lucidchart editor.

Can I show the difference between current and future states within the UML diagram?

Yes, use the layers feature to visualize current, ideal, or future states of any process or system side by side. Start with your current system and then create a layer depicting future states. Use hotspots to toggle between layers.
