What is itemis Model Viewer?

itemis Model Viewer – formerly named 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.
itemis Model Viewer provides various views to visualize a model’s outline and the properties of elements.

Installing itemis Model Viewer

In order to start working with itemis Model Viewer, formerly known as 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

The main use case of the itemis Model Viewer, formerly known as YAKINDU Model Viewer, is the browsing and exploration of Matlab Simulink and Stateflow models.

Accessing details

itemis Model Viewer, formerly known as YAKINDU Model Viewer, provides different means to access details about blocks. This includes

Searching in models

itemis 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 itemis Model Viewer, formerly known as YAKINDU Model Viewer, addresses these tasks with two features:

Requirements traceability for Simulink models

itemis Model Viewer, formerly known as YAKINDU Model Viewer, supports requirements traceability of Simulink and Stateflow models via its integration with itemis ANALYZE, formerly known as
YAKINDU Traceability.
