The simulation process creates three output log files. They are tx.dat, rx.dat, and error.dat. The rx.dat and tx.dat files each contain a detailed record of every TLP that was received and transmitted, respectively.
Tip: With an understanding of the expected TLP transmission during a specific test case, you can isolate a failure.
The error.dat file is used in conjunction with the expectation tasks. Only PCIe protocol errors will be listed in error.dat. DMA data mismatch or transfer errors will be printed out in the log file.
