INTRODUCTION
This section of the manual describes
the
test sections.
3.1
GET
TEST
DATA
Get'Test'Data asks for the test parameters
that
you
want
to input. Because this may not
be
the first time
that
this routine
is
called, you are given the option to retain most of the parameters
that
you have
previously specified.
You
are then prompted for the tests to be
run
and the ports to
be
tested.
3.2
SYSTEM
INTERFACE BOARD (SIB)
TESTS
This test section
is
composed of tests
that
relate to the
SIB.
The
SIB
is
actually the system interface
section of the TIC board. The test returns a logical value
that
indicates
whether
the tests succeeded and if
the AlB tests should begin.
Test'SIB calls the procedure for each test
that
is
s;'ecified by the parameters passed from Get'Test' Data.
Check'Error,
Print'Error'Prefix, and Print'Error'Status are utility procedures
that
are invoked
by
all
of
the
tests.
Test'SI13
loops through its testing sequence the number of times specified by
the
loop count passed
from Get'Test'Data.
Test
1.
1MB-SIB COMMUNICATION
--
Tests the
SIB
to insure
that
all allowable Intermodule
Bus
(1MB)
commands work.
As
each
I~B
command
is
executed, two types of
error
messages can
be
printed. The first type indicates
that
the instruction was not successful. The second type
indicates
that
the
SIB
response was not the expected response.
Test
2.
INITIAL REGISTER VALUES
--
Tests the values
that
are obtained from the
SIMB
registers
after
initialization. The value of each register to be checked
is
read. This value
is
then
compared with the expected value for the register.
If
there
is
not a match, an
error
message
is
output.
Test
3.
ERROR CIRCUITRY - - Tests
the
error
circuitry on the
SIB.
It
issues
an
illegal command and
verifies
that
it
is
detected.
It
then
checks the Error Clear mechanism of Register
!A.
Test
4.
RESET/INIT
--
Checks to make certain
that
an INIT command causes a reset of
the
registers
and of the error detection circuitry. First, the loopback bit of Register
!A,
the Diagnostic
Control Register,
is
written
with a
"0".
An INIT command
is
issued and should set
the
loop back bit. Register
IA
is
read to confirm this. Next, an illegal address command
is
issued
and the error bit
is
set. An INIT
is
issued to clear the
error
bit. This tests the operation of
the
MRST A line.
