INTERPRETING THE ERROR CODES

The only error type reported here is that the actual value did not equal the expected value.  The error reporting includes the source line in the verilog test script the actual value read and the expected value.  The script must be examined to determine what type of testing is being performed.  This error could indicate an error either in the load pipe circuitry, the memory, the ETLB circuitry, the vector register memory, the arithmetic logic units, or anywhere in between.
