Percepio Announces Tracealyzer 4 With a New User Interface and Stunning Live Views

Feb 20, 2018 |

Västerås, Sweden, 20th February 2018   * * *   Percepio announces a major update of Tracealyzer, its industry-leading tool for visual software tracing of RTOS-based embedded systems and IoT devices. Tracealyzer version 4 has been redesigned from the bottom up, from the data processing backend which is now up to 4x faster, to a fresh modern user interface with live visualization. It also sports a host of new features aimed at empowering embedded developers and enabling them to get their products to market faster with fewer bugs.

“This is the largest update of Tracealyzer ever, with a lot of new analysis and visualization features that users have been asking for. After mainly focusing on broad RTOS support, this marks the beginning of a new phase featuring more powerful, user-defined analysis. It’s a greater value for a greater number of developers. Tracealyzer 4 is a whole new experience and a very powerful tool for embedded software developers” says Johan Kraft, Percepio founder and CEO.

Some of the groundbreaking new features are

  • Unlimited tracing
    Monitor your application over long test runs, spanning hours, days or even weeks, and see analysis results, such as task execution times, immediately. Find interesting spots in the new trace preview and drill down into the details using the full power of Tracealyzer.
  • Advanced live visualization
    View the trace live while recording. Pause individual views to zoom in and inspect details while recording continues in the background. This way you can spot issues in the trace directly as they occur.
  • Network and I/O awareness
    Tracealyzer 4 provides better support for tracing Internet-of-Things devices and other connected applications with new awareness of network and I/O events. This allows for visualizing communication data rates over time, as well as the runtime interactions between tasks and communication interfaces like TCP sockets.
  • User-defined analysis
    Adapt Tracealyzer to your specific use case and see what really matters to you. Tracealyzer 4 allows you to define custom intervals that highlight and report the time between selected software events. Moreover, with user-defined state machines you can visualize any state information in the trace, from software state variables or logged hardware states, either as state transition graphs or shown on a time line, much like in a logic analyzer.

Tracealyzer version 4 will be on display in Percepio’s booth 4-305 at Embedded World in Nuremberg next week. It will then be generally available in early March for Keil RTX5, FreeRTOS and Amazon FreeRTOS. Support for other RTOSs will be added during the first half of 2018; see for details.

A single, node-locked license is USD 1,695/EUR 1,395 and other licenses are available, see Existing Tracealyzer customers are offered a discounted upgrade, starting at USD 495/EUR 395.

About Tracealyzer

Percepio’s market-leading visualization tool offers 25+ views, which are cleverly interconnected to allow viewing the trace from multiple perspectives, for instance CPU usage, memory allocation, task synchronization and communication events, as well as selected state variables and input/output values.

The insight provided by Tracealyzer facilitates debugging, validation, profiling, documentation and training. This can help avoid weeks of troubleshooting and vastly increase development speed.
