3.1.2 Transaction Layer Test Descriptions

3.1.2.1 Test 2-4. TXN_BFT_ErrorSignaling

ASSERTIONS COVERED: TXN.2.15#2, TXN.2.15#3, TXN.2.15#4

The intent of this test is to verify basic signaling functionality and message generation of a slotted Endpoint device.

Trainer Stimulus: trans_2-4_TXN_BFT_ErrorSignaling.peg

Recording Options: link_layer.rec

Verification Scripts: trans_2-4_TXN_BFT_ErrorSignaling.pevs

Test Algorithm:

1. Bring the link up.

2. Write 0x0000000F to the Device Control Register, to enable Error Reporting for all error types.

3. Send Memory Write request TLP with a wrong PSN number, which is supposed to generate a Correctable

error.

4. Send a Poisoned Memory Write request TLP, which is supposed to generate a Non-Fatal error.

5. Send a Malformed Memory Write request TLP (data/length field mismatch), which is supposed to generate

a Fatal error.

6. Read Device Status Register. All three error-type bits should be set.

Pass/Fail Criteria:

Test should successfully progress though all test stages.

All test stages should be executed without protocol violations.

Verify that:

a) Error messages of ERR_COR, ERR_NONFATAL, and ERR_FATAL types are sent in proper sequence as

responses to the errors created.

b) Error Reporting Status bits are set in the DUT Device Status Register (ERR_COR, ERR_NONFATAL, and

ERR_FATAL are recorded in these status bits).
