QTrace provides real-time ETM instruction tracing for ARM Cortex M3/M4 processors running up to 180MHz.
With a rich feature set at an affordable price, QTrace is a game changer and takes debugging to the next level.
Trace data is acquired at full processor speed and is continuously streamed, avoiding any hardware buffer limits. It is completely unobtrusive and requires no additional code.
The QTrace hardware probe and Windows® based QTrace Analyser run side-by-side with your existing IDE and JTAG adapter so you don’t need to change them.
The target ETM trace interface is configured using a debugger script run from your IDE. Scripts are supplied for most common IDEs.

There are a number of reasons for using QTrace. The bottom line is reduced development time and more deadlines met.
QTrace gives exceptional insight and detailed views of how your application is running in real-time. It helps to quickly locate bugs which would take much longer to find with conventional JTAG-only debugging.
You may think trace is only good for solving tough problems and profiling. QTrace excels here but its other features super-charge day-to-day debugging. After experiencing the power of live code coverage and having an entire execution history at your finger tips, you won’t want to debug without it.

The QTrace Analyser is a 64 bit PC application that runs on Windows 7 / 8.1 / 10.
It decodes and presents the trace data streamed from the QTrace hardware
probe and runs side-by-side with your existing IDE, ideally on a 2nd screen.
There are 3 primary trace data visualisations outlined below.
Shows live execution coverage as C/C++ and disassembly views as well as an execution heatmap. Enables loop timing, function navigation, conditional searches and more.Enlarge
Takes a snap-shot of program execution using several trigger options while tracing continues in the background. Displays a call stack as a function timeline.Enlarge
Displays sorted function statistics in real-time including number of calls, timing, interrupt frequencies. Highlights which functions are taking the most CPU time.Enlarge
Currently the QTrace Analyser currently supports the following devices:
* Limited supported for SoftDevices
1. In most cases, unlisted varients of the above devices will work with little or no modification to the supplied scripts. Contact us about support for varients or for devices from other manufacturers.
2. The QTrace Probe will work with any ARM Cortex M3/M4 device that complies with the ARM ETM timing specification.
Below is a summary of the system requirements for successful tracing.

QTrace is now an essential tool for me. It has dramatically reduced development time and changed the way I work. In QTrace Analyser I can monitor execution of code in real-time doing high-speed data acquisition, writing to a SD card and communicating over USB. All this without a single breakpoint – brilliant! I would highly recommend QTrace to anyone working with ARM Cortex-M.
QTrace has given a better, more reliable, connection and at higher core processor speeds than our competitors' unit. The live coverage works great and trace capture is invaluable to see where code is going wrong. The graphical timeline with its easy zoom and filtering makes visualisation so easy. The technical support has been great. A** service all-round.
QTrace is much more reliable than another vendors’ probe I was using. It is easy to set up and is a fraction of the cost (you need a separate JTAG adapter which I already had). The wealth of information from QTrace Analyser, with a full trace history always available on an exception or breakpoint, is invaluable. Highly recommended.
Low cost USB 3.0 powered trace probe enabling real-time instruction tracing for ARM Cortex M3/M4 processors running up to 180MHz.
The QTrace probe does not have integrated JTAG/SWD
The STM32Eval demonstrator is an optional add-on for the QTrace system and is designed to showcase the capabilities of QTrace without requiring an expensive development board or waiting for an in-house PCB to be ready
Contains everything needed to evaluate the QTrace system out-of-the-box. A quick-start guide highlights the key features of QTrace without needing to install an IDE or attach a JTAG adapter.
