What is YAKINDU Model Viewer?

YAKINDU Model Viewer (YMV) is a tool designed for the viewing of models created with MATLAB Simulink and shows the corresponding block diagrams with a similar look and feel as in Simulink. YAKINDU Model Viewer gives you the flexibility to quickly navigate, explore, and search very large and complex models. It provides browser-like navigation on diagrams, allowing a fast drill-down of the system hierarchy. It also features rich visualization, signal tracing, requirements tracing, gesture-based interactions, and much more. YAKINDU Model Viewer provides various views to visualize a model’s outline and the properties of elements.

Installing YAKINDU Model Viewer

In order to start working with YAKINDU Model Viewer, you have to install the software on your computer. We are assuming you have downloaded the software installer already. The installation process boils down to executing the installer and following its instructions.

Browsing models

Open MATLAB Simulink files with .mdl or .slx filename extensions, browse the model, navigate the system hierarchy, zoom and pan as needed.

Accessing details

Investigate the properties of model elements, display parameter values in blocks.

Searching in models

YAKINDU Model Viewer’s search functionality allows you to search for specific model elements. To start searching, click on the search button . It is labeled with a magnifying glass and resides in the top-right corner of the main view.

Tracing signals

YAKINDU Model Viewer lets you highlight and continue signal traces. See the complete active signal trace at a single glance in a flattened-out way, covering all affected subsystems throughout the system hierarchy.


Systems‌ ‌control‌ ‌engineering‌ ‌is‌ ‌a‌ ‌complex‌ ‌field‌ ‌and‌ ‌control‌ ‌engineering‌ ‌projects‌ ‌often‌ ‌require‌ multiple‌ ‌models‌ ‌and‌ ‌multiple‌ ‌documents.‌ ‌Often‌ ‌these‌ ‌artifacts‌ ‌appear‌ ‌as‌ ‌single‌ ‌files‌ ‌in‌ ‌the‌ file‌ ‌system,‌ ‌on‌ ‌external‌ ‌devices‌ ‌or‌ ‌within‌ ‌a‌ ‌version‌ ‌control‌ ‌system.‌ A systems control model often does not exist on its own. E.g. the model developer creates the model and writes a documentation about its behavior. Other users need that documentation when using the models to understand the underlying concepts, parameters, etc. The YAKINDU Model Viewer addresses these tasks with two features:

Requirements traceability for Simulink models

YAKINDU Model Viewer together with YAKINDU Traceability let you trace Simulink models (.mdl and .slx files) and navigate to the corresponding requirements or documentation files in external tools.

Advanced topics

YAKINDU Model Viewer provides several options to customize the user interface to better suit your needs. You can even control the visual appearance of model elements to a high degree.
