PowerDebug E40


A Powerful Standard Debugger

The PowerDebug E40 is our essential-line debug controller, offering you the performance to help you power through simple and complex debug tasks. It supports USB3 high speed connection to the host, and can be extended with logic analyzer modules. Our universal debug tool is designed to maximize your productivity and return on investment. The energy-efficient design allows a fanless operation for silent debugging.


Your Daily Debug Companion

Focus on today’s problems, knowing that we’ve already got tomorrows covered. Our PowerDebug E40 is a modern, high-performance, flexible tool that allows you to seamlessly transition from one embedded target to another. All driven from the same PowerView user interface that has been proven to significantly reduce training time and total cost of ownership.

Universal debug controller

Easily adapt the PowerDebug E40 to support any of more than 15 000 devices and more than 150 chip architectures by simply swapping the debug probe or adding a suitable license.

Super-fast debugging and low response times

Debugging large applications, running complex timing or trace analyses, or running automatic regression tests are time consuming. Even small savings add up over many iterations. The PowerDebug system reduces response times and improves upload/download speeds by placing a dedicated debug hardware accelerator close to the target and off-loading many debug decisions from the host. This makes debugging tasks magnitudes faster compared to host-based debug systems, slashing development times and costs.

Unlimited multi-core debugging

Debug multiple cores at the same time with a single debug probe, no matter the cores’ architectures. Control all cores even in a heterogeneous multi-core RISC cluster with multiple CPUs, DSPs, and other cores via just a single PowerDebug E40.

Energy efficient and silent debugging

The PowerDebug E40 runs without a fan, reducing power consumption significantly and eliminating fan related noise pollution. This allows you to concentrate even better on your development work on your embedded system.

Synchronize all your tools

Synchronize your PowerDebug E40 with other tools such as oscilloscopes and logic analyzers using the auxiliary I/O connector to send or receive trigger signals. The PodBus connector allows you to synchronize multiple TRACE32 tools for systems implementing multiple debug ports.

Add trace capabilities with CombiProbe

Enhance the features of your PowerDebug E40 by adding a CombiProbe, which provides the ability to support 4-bit off-chip traces. System traces and filtered program flow traces can be recorded, to get more insight on the dynamic behavior of the target application.


Flexible Target Connection

Switch between different targets without the need to exchange the PowerDebug E40 unit itself. Your PowerDebug E40 connects to your target via a modular debug probe. This probe is the target-specific part of your TRACE32 debug system, including the proper electrical interface and your architecture license.

Multiple target architecture licenses can be added to a single debug probe with a simple digital upgrade. If you have multiple designs with compatible electrical interfaces, you can support them all from one probe. If your multicore design shares a common debug interface, all cores can be debugged simultaneously with a single PowerDebug E40 and a single debug probe.

If a new target device uses a different electrical connection, you will only need to update the debug probe, or possibly only purchase a simple adapter, to immediately begin debugging. Your existing PowerDebug E40 and PowerView Software investments will continue to connect you to your target.

Configuration Examples for PowerDebug E40

Standard Debug - Lauterbach

Standard Debugger Configuration

A PowerDebug E40 with an IDC20A Debug Probe provides a standard configuration for debugging of a large number of targets. This configuration is perfectly suited for architectures like Arm Cortex-A/R/M, RISC-V, ARC, Xtensa, C6000, Hexagon, and many more.

Products shown:

Standard Automotive Configuration - Lauterbach

Automotive Debugger Configuration

If your target is based upon a core or SoC designed for automotive applications then this is the perfect configuration for you. The setup is well suited for architectures like TriCore/AURIX, PowerPC, RH850 and many more. For handling different ground levels, you can add an optional isolation adapter.

Products shown:

Dual Chip Tracing Configuration - Lauterbach

Dual-Chip Arm Cortex-M Tracing

For your safety critical applications you may implement dual-chip configurations based on Arm Cortex-M CPU cores. In this case you often want to trace the program flow of both Cortex-M cores concurrently. This configuration supports two independent debug- and trace-ports and can correlate the two 4-bit Embedded Trace Macrocell (ETM) streams with each other.
