Any test provides a status report at the end of simulation. The status report comprises the test pass/fail status, the total number of sent requests, the total number of received responses, and data integrity status (enabled/disabled).

Errors
The TEST FAILED status is reported in the following cases:
  • All Read/Write transactions are not completed (that is, all responses to the sent requests have not been received by the sender TG).
  • If the TG receives the response SLVERR/DECERR to the check for response correctness (BRESP/RRESP).
    Exceptions
    • If the exp_resp field is set as SLVERR in the CSV test, OKAY, EXOKAY, or DECERR responses from the slave are considered as failed.
    • If the exp_resp field is set as DECERR in the CSV test, OKAY, EXOKAY, or SLVERR responses from the slave is considered as failed.
  • Data integrity check should pass if enabled.
  • Any test sequence error occurring due to the input to the TG causes the TG to update the status to failed.
Warnings
  • Write data has been overwritten without reading it back.
  • Read occurred from an unwritten location.
  • The AXI Address 4K boundary is crossed while generating AXI transactions. Based on the input to the TG, and the address/length of these transactions have been adjusted to avoid 4K boundary crossing.
  • The TG is idle throughout the simulation if no traffic is sent from the TG. This warning occurs when the txn_cnt is set as 0 or when an empty CSV without any Write/Read commands specified is given to the TG.
  • Simulation ran for fewer cycles (<6000 AXI clock cycles), if the simulator run time is set as less than a 6000 axi_clock cycle period. This warning can be ignored if the simulation is terminated early due to any other fatal error.
