1.3 DIAGNOSTIC PROGRAM STRUCTURE
Each test
that
is
executed by
the
TICDIAG
is
a separate module. This enables you to select the tests to
be
run.
The TICDIAG routines
are
divided into two major groups in order to adequately test
t1le
hardware. The
two groups
are
the
tests for the System Interface Board
(SIB
- actually a section of the TIC board) and the
tests for
the
Asynchronous Interface Board (AlB - actually a section of the TIC board). The tests in the
SIB
section test
the
circuitry
between the
SIMB
and the
l-Bus.
They affect all ports. The tests in the
AlB section test
the
circuitry
from the L-Bus to the cable connector and affect only one selectable port
at
a time.
The TICDIAG loop
is
very simple.
It
calls Get'Test'Data to get input from the user. The
SIB
is
theh
initialized and the
SIB
tests, if selected, are run.
If
the
SIB
sectIOn
is
successfully completed, the AlB
is
initialized for testing
and
the selected tests
are
run. "ome of the data from Get'Test'Data
is
used
by
the
main program,
but
most
of
the data
is
passed directly to the Test'
SIB
and Test'AIB sections.

is
a
structure
chart
of the main program body.
