3.2.2 Transaction Layer Test Descriptions
3.2.2.1 Test 1-1. TXN_BFT_RequestCompletion
ASSERTIONS COVERED: TXN.2.7#9, TXN.2.21#15, TXN.2.21#19, TXN.3.1#1, TXN.3.1#2
Verify Basic Request and Completion handling of Root Complex devices.
Trainer Stimulus: trans_1-1_TXN_BFT_RequestCompletion.peg
Recording Options: link_layer.rec
Verification Scripts: trans_1-1_TXN_BFT_RequestCompletion.pevs
Test Algorithm:
1. Issue command to the Driver to clear all error status bits for the Root or Switch port to which the Device
Emulator is attached.
2. Issue command to the Driver to perform a Tag synchronization sequence (if needed) to ensure the next
transaction is done with an expected Tag value.
3. Issue command to the Driver to perform a Memory Read transaction.
4. Wait for the Memory Read Request and issue Memory Read Completion with Unsupported Request status.
5. Issue command to the Driver to reflect the current values of the Error Reporting Registers for the port to
which the Device Emulator is attached (using Configuration Writes).
6. Issue command to the Driver to clear all error status bits for the Root or Switch port to which the Device
Emulator is attached.
7. Perform Memory Read transaction from the DUT (command memory system area).
8. Issue command to the Driver to reflect the current values of the Error Reporting Registers for the port to
which the Device Emulator is attached (using Configuration Writes).
Pass/Fail Criteria:
Test should successfully progress though all test stages.
All test stages should be executed without protocol violations.
Verify that:
a) The DUT system constructed Memory Read Request and Completion TLPs properly.
b) The DUT did not set any error bits in its Device Status register.
c) The DUT did not set any error bits in the Advanced Error Reporting registers (if implemented). This includes the
Advanced Uncorrectable Error Status register, Advanced Correctable Error Status register, and Root Error Status
register.
If the DUT meets all these criteria, the DUT passes the test.
