Group B: Memory Tests
B1
TXP Scratchpad
The Group B tests verify all of the memory
blocks of the network adapters by writing
various data patterns (0x55aa55aa,
0xaa55aa55, walking zeroes, walking ones,
address, etc.) to each memory location,
reading back the data, and then comparing it
to the value written. The fixed data patterns
are used to ensure that no memory bit is stuck
high or low, while the walking zeroes/ones and
address tests are used to ensure
that memory writes do not corrupt adjacent
memory locations.

Group C: Block Tests
C1
CPU Logic and
DMA Interface
Verifies the basic logic functionality of all the
on-chip CPUs. It also exercises the DMA
interface exposed to those CPUs. The internal
CPU tries to initiate DMA activities (both read
and write) to system memory and then
compares the values to confirm that the DMA
operation completed successfully.
