Lauterbach, a manufacturer of microprocessor development tools, has added two new components to its Trace32 PowerTools product range.
Furthermore the delays for clock and data paths are setup automatically.
Lauterbach's Trace32-PowerTrace module allows tracing data of different trace-port architectures such as ETM for ARM cores, Nexus for Motorola's PowerPC or ST Nexus Super 10, as well as a variety of other architectures.
The trace module relies on a preprocessor that is specific to the target microprocessor.
In the near future the transfer rate of trace-port data is expected to cross the magic 200MHz line.
To ensure data integrity at those frequencies, it is crucial to terminate signal lines properly and compensate for signal level and delay issues.
Even relatively small delay discrepancies and/or out of tune voltage levels can lead to signal integrity issues.
Consequently the new preprocessors (eg for ST Nexus Super 10) use FPGA-based hardware to automatically set up proper voltage levels for termination and references for both clock and data, as well as delays for the clock signal and each data path individually.
If supported by the microcontroller, the automatic hardware setup can be double-checked by generating test pattern on the trace-port.
