11.2.23 Test 37: Bus Error Detection Test
This BIST checks the operation of the VME Bus Error Detection facilities available on the
VP 100/01x board. This BIST is composed of a series of sub-tests. The sub-test number is
selected by a BIST parameter; when run without parameters, all sub-tests are performed.
The available sub-tests are listed below, a (D) against the test indicates that it is executed by
default when no parameters are supplied.
0 - Perform all default (D) tests
1 - VME Bus Error Detection [by polling] (D)
2 - VME Bus Error Detection [by interrupt] (D)
3 - VME Bus Error Address Capture (D)
Error codes are detailed at the end of this section.
11.2.23.1 Sub-Test 1: VME Bus Error Detection [by polling]
This sub-test checks the operation of the VME Bus Error Detection facility. The Universe is
configured, for the duration of the sub-test, to map free PCI memory to a non-existent 64k block
of VME memory starting at address 0E0000000h. The sub-test reads the VME memory and
checks that a VME bus error is detected within 1 ms.
11.2.23.2 Sub-Test 2: VME Bus Error Detection [by interrupt]
This sub-test checks the operation of the VME Bus Error Detection facility. The Universe is
configured, for the duration of the sub-test, to map free PCI memory to a non-existent 64k block
of VME memory starting at address 0E0000000h. The sub-test reads the VME memory and
checks that the VME bus error generates an interrupt within 1 ms.
11.2.23.3 Sub-Test 3: VME Bus Error Address Capture
This sub-test checks the operation of the VME Bus Error Address Capture facility. The Universe
is configured, for the duration of the sub-test, to map free PCI memory to a non-existent 64K
block of VME starting at address 0E0000000h. The sub-test reads the VME memory and
checks that the VME Address Capture Read Register contains same value as the address of the
accessed VME memory.
Error codes:
0400h - sub-test does not exist
0410h - the Universe peripheral was not found
0411h - the South Bridge peripheral was not found
0420h - unable to clear the “VME Bus Error Detected” flag
0421h - unable to reset the “VME Bus Error Detected” flag
0422h - no VME Bus Error was detected
0423h - the VME Bus Error did not generate an interrupt
0424h - the VME Bus Error generated the wrong interrupt
0430h - timeout during address capture
0431h - wrong captured address
