Test Descriptions

This section provides descriptions of the diagnostic tests.

A1. Indirect Register Test

Function: Using an indirect addressing method, writing increment data
into MAC hash Register table and reading it back for verification. The
memory read/write is done 100 times while increment test data.

Default: Test Enabled

A2. Control Register Test

Function: Each Register specified in the configuration contents read only
bit and read/write bit defines. The test writing zero and one into the test
bits to insure the read only bits are not changed, and read/write bits are
changed accordingly.

Default: Test Enabled.

A3. Interrupt Test

Function: This test verifies the interrupt functionality. It enables interrupt
and waits for interrupt to occur. It waits for 500ms and reports error if could
not generate interrupts.

Default: Enabled

A4. BIST

Function: Hardware Built-In-Self-Test (BIST). This test initiates BIST and
waits for the test result returned by hardware.

Default: Due to the intermittent failure, this test is currently disabled by
default.

A5. PCI Cfg Register Test

Function: This test verifies the access integrity of the PCI config registers.

B1. Scratch Pad Test

Function: This test tests the scratch pad SRAM on board. The following
tests are performed:

Data Pattern Test: Writes test data into the SRAM and reads it back to
ensure data is correct. The test data used is 0x00000000, 0xFFFFFFFF,
0xAA55AA55, and 0x55AA55AA.

Alternate Data Pattern Test: Writes test data into the SRAM. Writes
complement test data into the next address. Reads back both to insure the
