Leverage the power of a full trace system geared towards your mid-range embedded design. The CombiProbe 2 is a compact debug and trace probe that provides our full feature set to embedded systems with compact trace ports of up to 4 bits wide.

BENEFITS

Utilize the Power of Both Debug and Trace

Our CombiProbe 2 is your perfect companion if you need full insight into what your embedded system is doing at run-time. Besides its comprehensive debug capabilities, it can capture real-time information like system traces and some compact parallel flow traces, which are essential for system profiling or safety certification. Trace recording often helps you launch your product faster and with more confidence.

Debug and Trace Two Multi-Core SoCs at the Same Time

With dual multipurpose connectors, our CombiProbe 2 enables you to debug and trace two independent multi-core SoCs at the same time.

Implement Numerous Architectures and Thousands of Devices

Our CombiProbe 2 supports thousands of device series from most major CPU architectures, including Arm Cortex, RISC-V, Infineon TriCore, Intel x86, dsPIC and MIPS. This vast range of support lets you easily switch from one chip and supplier to another while keeping the same CombiProbe 2 and user interface.

Capture Everything with Ultra-Long-Duration Trace

Long-term trace data recordings can be streamed to your host PC for later analysis. An average streaming speed of 140 MB/s ensures reliable transfers without data loss.

Profile your AUTOSAR Adaptive Platform

Our CombiProbe 2 is the perfect tool to profile your AUTOSAR Adaptive-Platform-based operating system. Together with our ARTI kernel driver, the CombiProbe 2 can capture task state information to visualize runtime statistics and timing charts.

Observe Your SoC from the Inside and Outside

In conjunction with the Mixed-Signal Probe, our CombiProbe 2 can sample analog and digital signals over time as well as decode the protocols sent via digital lines. If your SoC supports a suitable flow trace, the recorded signals can be correlated, giving you a clear, detailed, time-aligned view of the processor state along with its I/O signals.

Simplify Energy Profiling

Our CombiProbe 2 and Mixed-Signal Probe together can measure and record the power consumption of your embedded system over time. If you SoC supports a suitable flow trace, the power consumption can be correlated with the program flow, enabling you to efficiently profile your application’s power consumption and optimize any power-hungry code sections.

TARGET CONNECTION

Connect Your Target Optimally with Your CombiProbe 2

A whisker is the physical link from your target's debug and trace port to your CombiProbe 2. With the whisker’s transceivers located close to the target, it provides the firmest signal stability at the highest transfer speeds. Each of our whisker models is optimized to perfectly match the physical and electrical specification of the target's debug and trace ports.

Two multipurpose connectors enable your CombiProbe 2 to operate two Whiskers at once. Your CombiProbe 2 can debug and trace two completely separate target SoCs at the same time while allowing you to observe the precise timing of events within and between both SoCs.

Moreover, one multipurpose connector can be equipped with our optional Mixed-Signal Probe, enriching the trace analysis with time-correlated external analog and digital signals, enabling energy profiling, communication bus decoding, voltage fluctuation detection, and more.

Maximize Bandwidth with AutoFocus Technology

To connect your target’s debug/trace port to the CombiProbe, you need a whisker, which exists in several variants for different needs.

The most popular variants are the MIPI20T-HS and MIPI34 whisker. Both support our AutoFocus technology, which automatically adjusts the sampling point for each signal of your trace lines. This results in more reliable trace capture, with less concern about board routing, impedance, and length matching.

TYPICAL CONFIGURATIONS

Configuration Examples for CombiProbe 2

Debug and Trace of Dual-Chip Arm Cortex-M Processors

Safety critical applications often use two redundant processors making identical calculations. If the two separate embedded systems do not reach a consensus, the applications have to fall back to a safe state. A CombiProbe 2 with two Whiskers lets you develop this system by allowing you to record the dynamic behavior of both control units, timestamp the events with the same clock, and thus allow you to precisely follow the interaction between both units.

Analyze Automotive SoCs with AUTOSAR Adaptive Platform

Profile your AUTOSAR Adaptive Platform using the System Trace Microcell (STM). Arm SoCs can emit high-level messages created by the target’s software stack. Lauterbach provides an ARTI kernel driver which provides you with information about your AUTOSAR Adaptive Applications and their states by using the STM messages captured by the CombiProbe 2.

Using a Mixed-Signal Probe, you may capture any related external events e.g. CAN frames.

Debug Intel® CPUs

The MIPI60-Cv2 Whisker for our CombiProbe 2 was specially designed to support the Intel® Debug Port Specification. Thus, this configuration includes hook pins for special functions (e.g. stall execution during reset sequence), can receive PMODE packages, and has extra survivability features to manually control threshold voltages and slew rates. Furthermore, two independent JTAG chains and system trace are supported.

Benefit from RISC-V Compact Trace

While you can debug any RISC-V core with a CombiProbe 2, its real power is unleashed with SoCs containing RISC-V cores from SiFive. These cores often implement a Nexus trace with a 4-bit Pin Interface Block (PIB) off-chip trace interface, which allows you to record the program flow over time for profiling your code performance or to find tricky bugs which only appear in real time. Your CombiProbe 2 will support the upcoming N-Trace Specification once it is ratified by the RISC-V Foundation.

The Mixed-Signal Probe can record your system's power consumption and correlate it with the program flow to pinpoint power-hungry code sections.

SUPPORTED DEBUG PROTOCOLS

Maximum Performance for All Debug Protocols

JTAG (IEEE 1149.1)

JTAG is the communication protocol commonly available on most CPUs. Originally developed for Boundary Scan device testing, JTAG allows an external tool to communicate with a Test Access Point (TAP) controller inside a chip. A TAP is the connection to the debug infrastructure within a chip. TAPs can be chained to allow debugging of several cores via a single debug probe.

cJTAG (IEEE 1149.7)

Compact JTAG (cJTAG) is a technology based on JTAG which reduces the pin count of the debug interface by serializing the JTAG communication between the debugger and the core’s Test Access Points (TAPs). Multiple chips can be supported in a star topology. Compared to normal JTAG, it saves costs for physical pins with a slightly reduced debug performance.

CoreSight Serial Wire Debug (SWD)

SWD (Serial Wire Debug) is a 2-pin debug interface, defined by Arm® and optimized to access the CoreSight™ debug infrastructure with maximum performance.

Infineon DAP

The Infineon Device Access Port (DAP) is a versatile debug interface with two or more pins. Its CRC6 protection makes it robust for noisy environments. It supports much higher frequencies than JTAG and also allows transmitting real time trace data with low-to-medium bandwidth.

Intel® Out Of Band (OOB) Hosting DCI

The Intel® DCI OOB protocol in one method to access the Intel® Direct Connect Interface (DCI) to debug Intel® targets. It uses the pins of the USB 3.2 Gen 2x1 port. It provides early boot access.

New and Emerging Technologies

TRACE32 works at the forefront of debug technologies and tools, with Lauterbach engineers often sitting on working groups and steering committees for all aspects of embedded software and systems. Some new interfaces supported by Lauterbach are SPI debugging, Debug over USB, Debug over CAN and Debug over I3C.

SUPPORTED TRACE PROTOCOLS

Compact Trace for Ambitious Developers

Cortex-M ETM and ITM

The Embedded Trace Macrocell (ETM) provides real-time trace information of the program flow and data accesses. Many Cortex-M processors include a 4-bit ETM combined with a CoreSight Instrumenta-tion Trace Macrocell (ITM), allowing our CombiProbe 2 to capture program and data trace along with OS and application events.

RISC-V Nexus

Nexus trace (or IEEE-ISTO 5001) is a fairly ubiquitous embedded debug and trace protocol used by many CPU vendors, providing real-time traces of the program flow and data accesses. Some RISC-V devices support Nexus trace features that are compressed in a manner suitable for capture by the CombiProbe 2.

TriCore Compact Function Trace

On many TriCore processors, the Compact Function Trace (CFT) provides data about function entry and exit points. This data can be continuously streamed via an Infineon DAP to the CombiProbe. Additionally, it is possible to gather profiling information of an AUTOSAR Classic operating system.

MIPI System Trace

The System Trace Protocol (STP) is designed to analyze the dynamic behavior of a real-time application on a high level. System trace messages are mostly generated by instrumentation functions in the application code running on the CPU. For profiling the AUTOSAR Adaptive Platform, Lauterbach provides a suitable instrumentation module.

iFlowtrace™ for MIPS

The iFlowtrace ™ is a lightweight, instruction-only tracing scheme of MIPS32® M4K, M14K and PIC32MX/MZ cores. Its compact off-chip trace port is perfect for the CombiProbe 2.
