Generating Information for Diagnosing Computer Hardware

      Disclosed is an improved method of generating information for
diagnosing hardware errors in computer systems.  For this purpose, a
single source (Fig. 2) is used which eliminates the disadvantages
inherent in the prior art approach (Fig. 1).

The following sources are included in the approach of Fig. 1:

o   A reference code which is generated in the analyzer of the
    designer for the hardware or the microcode and which is displayed
    to the operator in response to an error.
o   A failure information table (FIT) which contains the reference
    code and associated information (e.g., field replaceable units,
    test procedures, etc.) for verifying the diagnosis.
o   Error description in verbal form for support.

The disadvantages are: Poor maintenance, as three different sources
have to be synchronously updated and maintained; no inconsistency
check (double reference code); elaborate and expensive, as the
designer has to use different source files of different formats; no
automatic file generation means.

      The single source method (Fig. 2) uses only one source program
with a standardized RCDL (Reference Code Definition Language).  This
language includes the permissible repertoire for reference code
definition.  The actual source program 1 is compiled by compiler 2
and the RCDL program parts by the RCDL compiler 3.  The program code
modules 4, supplied by compiler 2, and the FIT...
