Diagnostics
Testing Register Accesses: dalNbcsSswDiagTestReg
Verifies the hardware access to the device registers by writing and reading back values. The
following types of register tests can be performed --- single value write/read and walking ones.
In addition, each of these tests can be run on the full range of registers.
The write/read test writes the specified value to the specified register and verifies that the same
value is read back. The walking ones test performs a series of writes to the specified register.
Testing RAM Accesses: dalNbcsSswDiagTestRam
Verifies the hardware access to the device internal RAM by writing and reading back values. The
following types of RAM tests can be performed: single write/read, walking ones, migrating ones,
and aliasing. Note that both connection maps are tested for all types of tests listed above. The
first three types can be performed on either a user-specified range or the entire RAM. Aliasing is
always performed on the entire RAM.
