CMI Test The cmiTest verifies that control messages can be correctly sent from
any ASIC to any ASIC. It also tests that the checksum check is ok. The
switch must be offline.

SRAM Retention Test The sramRetentionTest verifies that data written into the ASIC
memories are retained and that data bits do not “drop” when read
after some amount of delay since the write. The switch must be
offline.

cmemRetention Test The cmemRetentionTest verifies that data written into the SRAMs
that make up the central memory are retained and that data bits do
not “drop” when read after some amount of delay since the write.
The switch must be offline.

and implemented using content addressable memories (cam) are
functioning correctly. The switch must be offline.
