Aurix Specific Trace Use Cases

DAP Streaming -  Upload While Sampling (UWS)

•Allows Upload of Trace Data from EMEM to Host PC (winIDEA) while Trace Recording is running

•If Upload Bandwidth is higher than the Trace Data Generation Rate, Upload While Sampling can run infinitely

•Ideally suited for (long-term) OS Profiling

•DAP/DAPE II Active Probe allows DAP Operation at maximum 160 MHz for optimized Streaming Bandwidth

•A minimum of 2 (better 3) EMEM Tiles need to be available for Trace

 

 

DMA Trace

The winIDEA Trace Analyzer allows full utilization of the extremely versatile configuration options of the AURIX MCDS On-Chip Trace functionality. This allows, for instance, tracing of SRI bus transactions of specific bus masters such as the DMA controller along with the CPU instruction trace or OS task trace.

 

 

 

Trace of CPU Performance Counters

The winIDEA Trace Analyzer allows full utilization of the extremely versatile configuration options of the AURIX MCDS on-chip Trace functionality. This allows, for instance, a real-time trace of the CPU-internal performance counters, measuring performance parameters such as Instruction Execution rate, Cache Hit / Miss rates, etc.

 

 

 

Compact Function Trace (CFT)

CFT is a feature of the MCDS Processor Observation Block (POB). Its goal is to reduce trace bandwidth, while providing the ability to trace function execution. Trace messages are only generated upon a function call and function return. Also, indirect calls (e.g. Interrupt Service Routines) generate a trace message.

This concept brings big savings especially when long functions are executed, as all instruction execution inside the function generates no trace data. However, the CFT concept relies on consistent function call-return sequences. Certain compiler optimizations “violate” this constraint and thus CFT-based function profiling may not be applicable.

 

 

 

ADIO & CAN Trace

A trace recording via DAP UWS allows a time correlation with Analog/Digital or CAN/LIN bus signals captured by means of the ADIO and/or CAN/LIN Add-On Module of the iC7max/iC5700.

 

 

 

 

Aurix Debug and Trace Architecture

Infineon 32-bit Aurix production devices provide debug capability (OCDS) by default while they don’t provide a Trace functionality. Infineon offers a dedicated pin compatible Emulation Device (ED), which features also the Trace functionality. BlueBox connects to the OCDS debug module through fast DAP debug interface or an optional slower JTAG debug interface.

Trace on the Emulation Device is built around the MCDS and the EMEM subsystems. The MCDS is the core component and connects to all internal buses being visible to the trace and on the other side to the EMEM, a trace storage buffer from where the trace data is uploaded to the PC.

Typically EMEM trace data is uploaded off the chip through the DAP debug interface. Due to a limited bandwidth and being also shared with the OCDS module, optionally a dedicated DAPE debug interface is available for uploading the trace data from EMEM.

Another alternative to the DAPE debug interface, is a high-speed serial AGBT interface, which allows trace uploads at transfer rates of several Gbit/s.
