OptoLyzer® Studio

The Universal Multi-Bus Network Development Tool


Areas of Application

The idea behind K2L´s new and state-of-the-art software generation OptoLyzer Studio is to provide the automotive market with a single solution that includes all required capabilities for simulation and test as well as for deep system analysis for all common networks of a car environment.

Tailored software editions assure to have the right capabilities and to support all customer specific use cases. Therefore, each software edition includes a different set of components as shown below:

  Entry Edition Foundation Edition Professional Edition
OptoLyzer Studio GUI OK OK OK
Device Manager OK OK OK
Code Generator     OK
Test Framework     OK

Entry Edition: offers the opportunity to analyze the traffic on one CAN or LIN channel by combining the OptoLyzer Studio GUI either with a Microchip CAN Bus Analyzer or a LIN Serial Analyzer.

Foundation Edition: provides all capabilities for testing and analyzing network traffic over leading-edge bus systems integrated in the car.

Professional Edition: integrates the complete feature set including the OptoLyzer Studio GUI, a Code Generator and the possibility to combine own test code with the OptoLyzer Studio Test Framework.

There is also a free of charge variant of the OptoLyzer Studio available that allows viewing of existing files without any hardware support.
To use this version just download the OptoLyzer Studio software without activating a license key.


Flexibility meets Innovation

Automotive engineers are continually grappling with challenges such as shorter development cycles and higher design complexity. This is our motivation to bring the new OptoLyzer Studio software to the market. It offers users a comprehensive and easy-to-use tool chain that addresses the aforementioned issues and performs as needed, every time, for all applications and use cases within every major automotive network.
The universal OptoLyzer Studio software reduces complexity and cost and shortens time-to-market for all activities related to test and simulation and covers all requirements for conducting analysis and verification, helping to ensure quality from the earliest design stages. In addition to supporting all major automotive buses, the .NET-based tool leverages cost-effective open technologies that allow customized extensions, making it the most flexible option to the automotive industry.

OptoLyzer Studio GUI

The OptoLyzer Studio main GUI includes a state-of-the-art software concept that is based on .NET technology. This component is more than a pure viewer application since it assures powerful monitoring capabilities in traces as well as in graphs next to an Activity section where users can create own tasks by generating messages and setting bookmarks.

The intuitive ribbon concept facilitates easy access to the available functions of the OptoLyzer Studio so that steep learning curves are a thing of the past. Dockable windows add clarity and tidiness.

The Trace View, the Signal Graph, the Activity View as well as the Filter View are the centerpieces of the new software. The Trace View neatly arranges the messages of the different bus systems. The Signal Graph visualizes signals over the course of time. This fosters the understanding of what is going on in the system – not just for visually inclined people. Messages can be injected into the considered system with the help of the Activity View. In fact, the Activity View offers a kind of graphical programming capabilities, i.e. it allows the definition of complex procedures even with special timing behavior inside the GUI.

The OptoLyzer Studio Software GUI provides further advantages:

  • Unlimited size of log files.
  • Expandability assures to combine the software with K2L and Microchip interfaces, with own hardware or with 3rd party solutions.
  • Drag`n`drop options offer a fast way to move and copy elements, like signals or filters, from one window to another and therewith help to increase productivity.
  • A Detail View displays catalog information with all relevant information of selected messages.
  • Different message properties can be displayed.

Device Manager

The Device Manager View provides the functionality to manage connected devices and configure the state of all supported buses. It is part of the OptoLyzer Studio GUI and enables users to activate or deactivate connected devices, change transceiver status and regulate bit rates of the respective networks.

Device Manager View


The OptoLyzer Studio provides a comprehensive tool set to cover the complete process of automotive development cycles. With a single tool that supports all widespread automotive buses, OptoLyzer Studio serves the need of designers, developers, testers and system integrators required to bring sophisticated automotive systems to market in a timely manner. The software can be combined with K2L, Microchip and also 3rd party hardware development tools for devices and systems which enable data communication over leading-edge automotive networks such as CAN, CAN-FD, LIN, FlexRay® and MOST®.
