The Quad SPI example design does not write much data into the slave device. It reads back and compares the read data with the written data. The signal status is used to convey information about the test case results.

Status (1 downto 0) indicates whether the test passes, failed or hanged.

01 - Test completed successfully. This means the read data matches with the written data.

10 - Test failed. Read data does not match with the written data—data mismatch

11 - Test hanged. The core is hanged at some particular instruction.

Status (9 downto 2) gives the index of MIF where the test stopped.

Note:   The Done signal goes High after the test is complete.
