INTERPRETING THE ERROR CODES

When this test reports an error, a customer can only determine that there is a problem with the CPU board and that is must be replaced.  For the factory test technician, the error reporting includes a line number of the source code for the verilog testing.  The source code must be examined to determine what particular cicuit was under test at the time the error was reported.
