Cost-Effective All-In-One Debug and Trace Module
Leverage the power of a full debug and trace system specifically geared towards your Arm® Cortex®-M embedded design. µTrace® is our cost-effective all-in-one solution that provides our full feature set for Cortex-M microcontrollers implementing a compact trace port of up to 4 bits.
µTrace® is also available for debugging 32-bit RISC V cores. Trace support for RISC-V will be added immediately after adoption of a trace standard by the RISC-V Foundation.
Enjoy Uncompromising Lauterbach Quality, Functionality and Support
µTrace® provides you the same features that our industry leading high-end products are known for: highest quality, exceptional functionality and superior support. In addition to its leading debug capabilities in the Cortex-M market, µTrace® can capture real-time information like system traces and parallel ETM flow traces, enabling e.g. Code Coverage and Code Profiling. In many use cases, real-time trace can bring embedded designs to market faster, safer and with more reliability.
Leverage the Highest Performance in the Industry
Our µTrace® supports data rates up to 400 Mbit/s per trace line from the Arm® CoreSight™ Trace Port Interface Unit (TPIU). This is 30 percent faster than competing trace products for Cortex-M-based embedded systems. To ensure proper sampling at these speeds, our AutoFocus eye-finder automatically detects the perfect sampling point for each trace line.
Trace Ultra Long with Highest Streaming Performance
Capture extremely long-term trace recordings by streaming the trace data to your host PC for later analysis. An average streaming speed of 140 MB/s (1.2 Gbit/s) ensures a reliable transfer without data loss and represents the highest data rate in this market segment. Our TRACE32® PowerView Software updates and displays the code coverage results on-the-fly, while the target is running.
Squeeze the Last Milliwatt Out of Your Application
By adding our optional Mixed-Signal Probe, your µTrace® can record detailed measurements of the power consumption of your embedded system over time. If your Cortex-M additionally supports ETM off-chip trace, you can perform Energy Profiling to locate all power-hungry code sections, which is especially important in power sensitive applications.
Observe Your SoC from the Inside and Outside
In combination with the Mixed-Signal Probe, your µTrace® can sample analog and digital signals and decode the protocols send on digital lines. If your Cortex-M supports ETM flow trace, the recorded signals can be correlated, drawing a coherent picture of what is happening simultaneously inside the chip and outside at the pins and peripherals of your SoC package.
Debug Any Cortex-M and Any RV32 Chip - Including Hidden Cores
By using our µTrace® you can debug an industry-leading number of Cortex-M and RV32 cores implemented in both single-core and multi-core microcontrollers and SoCs: today we support over 7,000 chips supplied by dozens of manufacturers. New chips are regularly added, and we often support new chip designs as they are announced. Beyond our extensive support of publicly known IP, it can also debug cores that are never publicly announced, keeping your confidential IP your own secret.
Enjoy Our Full Feature Set and a Familiar User Interface
With PowerView, we have developed a unique user interface that remains consistent across our products and supported OSes. Using µTrace®, you benefit from our full debug and trace functionality and can get started immediately without any additional training.

4 The streaming rate defines the per-second throughput of data that can be transferred on-the-fly to the PC. If the trace-port rate is below the average streaming rate, a practically infinite recording time (limited only by disk space and speed) possible. The peak-rate is possible temporarily and is compensated by the internal memory of the PowerTrace extension.
5 µTrace® for RISC-V will support off-chip trace promptly after adoption of a trace standard by the RISC-V Foundation.

Configuration Examples for µTrace®
Application Profiling & OS-Aware Cortex-M Debugging
Beyond debugging, µTrace® supports the recording of the program flow and user-selected data address accesses over time. You can imagine it like recording a movie of what is happening inside the chip in real-time by utilizing Embedded Trace Macrocell (ETM), Data Watchpoint and Trace unit (DWT) and CoreSight ITM. Our PowerView software correlates both trace streams emitted by the Trace Port Interface Unit (TPIU). As a result, you can review precisely which instruction caused a particular data access. The correlation also enables you to profile your application with the awareness of the task switches by your target’s Operating System.

Record Digital/Analog Signals plus Correlation with Program Flow
For the numerous Cortex-M chips implementing a CoreSight Trace Port Interface Unit (TPIU), µTrace® can correlate digital/analog signals with the program flow because it provides a common time-stamp for both recordings. You can achieve very long trace recordings by streaming both program flow trace and signal recording on-the-fly to your host computer. For decoding the recorded digital signals, our TRACE32® PowerView software comes with a number of built-in protocol analyzers for common interfaces such as CAN, USB and I2C. It can be easily extended to add your own custom protocol analysis capabilities.

Debugging of 32-bit RISC-V (RV32) Cores
µTrace® for RISC-V is a cost effective solution for debugging myriad 32-bit RISC-V cores and provides all of the well-known TRACE32® features. When you want to eventually debug additional instruction sets, you can easily switch over to any of our other debug products while using the same debug software. Once the RISC-V foundation has released the upcoming N-Trace standard for RISC-V cores, your µTrace® will be updated to support real-time trace starting with the subsequent TRACE32® PowerView software release.
