Intel® System Debugger includes a Python*-based command line interface for capturing and decoding system trace called TraceCLI. Developers can use the TraceCLI Python package for automating trace capture and the System Trace UI for development and manual trace capture.

This project demonstrates decoding a trace file using the two methods mentioned above (trace UI and TraceCLI).

Using the System Trace UI

Launch Intel® System Debugger
Using the Eclipse Quick Access control (Ctrl+3), open the System Trace perspective:

In the System Trace wizard, select Set up project.

Enter a project name

5. Choose Manually select target. Select “Comet Lake U” and click Next.

Select the Intel® Silicon View Technology (Intel® SVT) Debug Class (DbC) USB Debug Cable and click Next.

Since this is a file decode, uncheck ‘Configure provider’ as well as ‘Connect to target on finish’.

Provide a trace configuration name

Import Trace Capture.

Alternatively, in the Project Explorer, expand the ‘capture’ node and click Import Trace Capture.

Select an example file at <isd install folder>/system_trace/examples/input/mipi_aet_fake_trace.bin.bin

Select the imported capture for decoding

Ensure that CMP General decode use case is selected and click OK.

‘MessageView001’ opens showing decoded trace

Using the TraceCLI

TraceCLI has three usage models (console, file decode, and streaming)

> intel_tracecli  --help
usage: intel_tracecli [-h] [-v] [--pvss PVSS] [--target TARGET]
                      [--usecase USECASE] [--transport TRANSPORT]

positional arguments:
  {console,decode,stream}
    console             Run interactive mode
    decode              Decode a trace capture file
    stream              Capture and decode traces

Basic usage guideline for file decode:
  1. session = trace.filedecode_session()
  2. session.interactive_setup()
  3. session.decode_file('ipc_trace_test.bin')

Basic usage guideline for streaming:
  1. session = trace.stream_session()
  2. session.interactive_setup()
  3. session.start_stream_capture()
  4. session.enable_trace()
  5. session.disable_trace()
  6. session.stop_stream_capture()

Other options (Examples):
- session.set_decoder_parameter('MIPI_Decoder', 'startAtAsync', 'false')
- session.csv_columns.extend(['MasterID','ChannelID','payload','Summary','PacketType'])
