Table 33 io3000 Class 2 subtests
Subtest Name Description
200 Context/
shared
memory read/
write
Writes to the first 64-bit location of each
context SRAM and reads them to verify
that they can be uniquely accessed.
205 Context/
shared
memory
access width
Verifies that all supported access widths
of context SRAM function properly by
writing and reading the first 64-bit
location.
210 Context/
shared
memory
march C-
Verifies that coverage for full march C-
will increase from approximately 99% to
100% of targeted fault using a bitwise
march C- algorithm.
215 Context/
shared
memory
pattern
Writes and reads random pattern to all of
context/shared memory. The random
pattern can be modified by changing the
random seed option. Also, a user-specified
pattern can be used by setting the user
pattern options.
220 Context/
shared
memory
parity
detection
Verifies the ability of SAGA to detect
parity errors on reads from context/
shared memory. This test uses the FCC
bit (force parity error to context SRAM) to
write a parity error into context SRAM.
The bad parity is read out, causing a
parity error to be detected and logged in
the SAGAs Error Cause CSR.
225 Prefetch
memory read/
write
Verifies that the first 64-bit location of
each prefetch SRAM uniquely accessed.
230 Prefetch
memory
access width
Verifies that all supported access widths
of prefetch SRAM function properly by
writing and reading the first 64-bit
location.
