16.11. The Traffic Generator 2.0 Report

The traffic generator report provides information about the configuration of the Traffic Generator 2.0 and the result of the most recent run of traffic.

Understanding the Traffic Generator 2.0 Report

The traffic generator report contains the following information:

  • A Pass flag value of 1 indicates that the run completed with no errors.
  • A Fail flag value of 1 indicates that the run encountered one or more errors.
  • The Failure Count indicates the number of read transactions where data did not match the expected value.
  • The First failure address indicates the address corresponding to the first data mismatch.
  • The Version indicates the version number of the traffic generator.
  • The Number of data generators indicates the number of data pins at the memory interface.
  • The Number of byte enable generators indicates the number of byte enable and data mask pins at the memory interface.
  • The Rank Address, Bank address, and Bank group width values indicate the number of bits in the Avalon address corresponding to each of those components.
  • The Data/Byte enable pattern length indicates the number of bits in the fixed pattern used on each data/byte enable pin.
  • The PNF (pass not fail) value indicates the persistent pass/fail status for each bit in the Avalon data. It is also presented on a per-memory-pin basis for each beat within a memory burst.
  • Fail Expected Data is the data that was expected on the first failing transaction (if applicable).
  • Fail Read Data is the data that was received on the first failing transaction (if applicable).
