1 The streaming rate defines the amount of data which can be transferred on the fly to the PC per second. If the trace-port rate is below the streaming rate in average, a practically infinite recording time is possible. The peak-rate is possible temporarily and is compensated by the internal memory of the CombiProbe.

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.

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.
