Electronic Card Fault Simulator to Building Block Tester Data Path

      Disclosed is a software package which transforms the Cadence*
Fault Simulator/Card Design System data and ports it to the Fluke**
Spectrum Building Block Tester.  The Cadence Fault Simulator is
enhanced by using IBM's Gauntlet logical probe capability and file
creation function.

      The invention is a method which transforms the Cadence Fault
Simulator/Card Design System data and ports it to the Fluke Spectrum
Building Block Tester.  IBM's Gauntlet acts as a shell around the
Cadence Fault Simulator and creates the All Events Trace (AET), Cross
Reference (XREF), Fault Reference (FREF), General Information File
(GIF) and Logic Model (LM) data files.  The environment under which
the data path runs is OS/2*** Presentation Manager.

      This process is divided into three sections:  Front End
Processing, Utilities for the Test Engineer and Back End Processing.
The most significant part is the Back End Processing which links the
Functional Self Test (FST) code with the logic analyzer setup and
capture function and supplies diagnostic data for the electronic
card.  The flexibility exists to install the entire data path or
parts of it at the test engineer's work station and/or at the
Building Block Tester.

1.  Front End Processing - The Front End Processing is the initial
    manipulation of the data files.  The files are received and
    audited for validity.  After successful completion, internal
    binary tables are created.  The Physical/Fixture data is then
    added to the binary tables.  These tables are later used for the
    Utilities and/or Back End Processing.

2.  Utilities For Test Engineer - A variety of utilities are provided
    to the test engineer to aid in information gathering, statistics
    reviewing, and diagnostics.  The utilities are described below:

    a.  Print All Events Trace (AETPRINT) - This utility prints data
        from the All Events Trace (AET) file.  The user is given the
        flexibility of viewing any data commands of interest.  The
        output can be represented in a number of formats, ranging
        from hexadecimal to a variety of easily readable listings.

    b.  All Events Trace Statistics (AETSTAT) - This utility lists
        each command found in the AET in addition to the number of
        occurrences of each and total number of bytes.

    c.  All Events Trace Strip (AETSTRIP) - This utility removes any
        unwanted commands from the AET.

    d.  Component Test Coverage (COMPTEST) - This utility lists each
        component on the card, the number of faults per component and
        the number of detected faults per component.  From this the
        percent test coverage per component and card is calculated.

    e.  Pin Usage Listing (PINUSE) - This utility lists all the card
