For fast output of important system information at runtime, some cores now have simple trace ports. These ports enable an application program to make user-defined data visible offchip. For recording and processing this data, Lauterbach offers a new tool called CombiProbe. The hardware and operation of Combiprobe is described in detail in this paper.
For complex test cases, CombiProbe can also be used in conjunction with TRACE32-PowerTrace. Since all Lauterbach tools share a common time base, important system information can be placed in a direct chronological context with the program/data flow of the core.
