Once again, embedded world 2025 is just around the corner. The trade fair is the global platform, the industry meeting place for the embedded community, leading experts, key players and industry associations. It offers an unparalleled insight into the entire world of embedded systems: from components and modules to operating systems, hardware and software design, testing and M2M communication.

RAZORCAT at the embedded world 2025 At embedded world 2025 in Nuremberg, RAZORCAT will be presenting the latest developments for testing safety-critical systems in hall 4 at stand 4-420 - secure your free ticket with the code ew25543105 on the organizer's website. At embedded testing 2025, everything revolves around software testing in the embedded sector. As a long-standing member of Embedded4You, Razorcat will be there again - don't miss the presentation by  Michael Wittner (CEO, Razorcat Development GmbH): “Security in the variant forest: How hyper-coverage uncovers hidden code”  The presentation will take place on March 25, 2025 from 15:40-16:25 CET.

TESSY v5.1 - More efficiency for your tests   The latest version of TESSY v5.1 for Windows & Linux optimizes the testing process with powerful features: Test Cockpit - Identifies relevant source files and summarizes coverage results clearly. Hyper Coverage - Analyzes code coverage directly at the source file level to reveal untested code. Hardware integration - The TESSY THAI interface allows hardware signals to be integrated into tests via Raspberry Pi or Arduino.

TESSY feature preview: AUTOSAR support Did you know that Razorcat Development GmbH has joined the AUTOSAR consortium?   This means seamless testing of AUTOSAR software components (SWC) with the unit and integration test tool TESSY - making testing even more efficient and intuitive.   AUTOSAR (AUTomotive Open System ARchitecture) is a global development partnership that standardizes the software architecture for electronic control units (ECUs) in automobiles. It enables interoperability, scalability and reusability of software components across different automotive platforms and manufacturers.   For TESSY users, this means Automatic RTE generation  TESSY automatically generates the AUTOSAR runtime environment (RTE) for a SWC based on the ARXML model description file. Consistency checks  Various checks ensure the consistency of the AUTOSAR model against the implementation code or dynamically during test execution. Clear interface representation  The C code interface is presented side-by-side with the AUTOSAR port interfaces, facilitating stimulation and testing with all necessary inputs and expected results. Seamless test data processing The ports and interfaces of the SWC are available in the TESSY test interface and test data editor, allowing intuitive test data entry directly in the graphical user interface. AUTOSAR in TESSY makes testing even smoother and more reliable.   Experience the elevator demo live: Model based tests up to the target hardware    Razorcat will be presenting the well-known elevator demonstrator at the trade fair with the middleware HIL4you from its partner iSyst Intelligente Systeme GmbH. Together with the CCDL and TOP tools, Razorcat will be demonstrating functional tests and safety tests that can be developed on the model and then run on the real target hardware.   You haven't tested TESSY yet?

SystemView now with multicore support SEGGER's real-time software verification and visualization tool SystemView has been upgraded with multi-core support, extending its capabilities to systems with multiple CPU cores on a single chip.   Using SEGGER's Real-Time Transfer technology, a single J-Link debug probe can now collect data from multiple cores in real-time. The data is streamed to the host where it is immediately analyzed and visualized. All events are recorded and can be stored for analysis and documentation purposes.   For each core running instrumented firmware, events such as task context switches, interrupt executions, function calls, heap and stack usage, data samples, log messages and more can be recorded.   Each core records events in its own SystemView channel, just like in a single-core recording scenario. Each CPU core can be viewed individually or as a group of all cores, making it easy to see and verify CPU interaction and associated timing.   SystemView is cross-platform (Linux, macOS and Windows) and can be easily downloaded for use on ARM, Intel or Apple silicon. Under SEGGER's Friendly License, no registration is required to download SystemView. Use is free for educational and non-commercial purposes, the software can be evaluated without restrictions on code size, features or time.

J-Link and Flasher for STELLAR P and G MCUs   SEGGER's J-Link Debug Probes and Flasher In-Circuit Programmer now fully support STMicroelectronics' Stellar P and G family of microcontrollers designed specifically for the automotive industry.   With multiple cores, Stellar devices enable designers to consolidate multiple ECUs into a high-performance ECU with a single Stellar MCU. This approach simplifies system architecture while providing the ability to handle various automotive applications.

Embedded Studio and J-Link for NXP’s MCX family SEGGER's J-Link Debug Probes and Embedded Studio IDE now support NXP's next-generation MCX MCUs.   This provides embedded developers working with these chip families access to J-Link's ultra-fast J-Link debugging and programming capabilities, as well as Embedded Studio's flexibility and efficiency.

SEGGER for Nordic Semiconductor nRF54L15 Cortex M33 SEGGER's J-Link, J-Trace Debug Probes and Flasher Programmer now offer debug and flash programming support for Nordic Semiconductor's ultra-low-power, multi-protocol and wireless nRF54L15 system-on-a-chip (SoC) cores.   Flasher programmers support the nRF54L15 SoC Arm Cortex-M33 cores, while the RISC-V coprocessor gains debug support for J-Link and J-Trace devices.   A complete list of devices supported by Embedded Studio and J-Link can be found here. The list of devices supported by J-Link and J-Trace is available here.   You can find SEGGER Microcontroller at embedded world 2025 in hall 4, booth 4-367.

Our technical world is turning fast. You probably know my favorite motto: “If you don't move with the times, you move with the times”. Take time for the trade fair and give your employees the opportunity - it will pay off for you!   With this in mind, I wish you good networking in Nuremberg. Sincerely Yours, Marian A. Wosnitza   “The future is the time when you regret that you didn't do what you could do today.” (Count Leo Tolstoy, 1828-1910, Russian writer)
