Description :
|
| 6 |
|
|
In this test, we use Altera Tranceiver as Link Partner
|
| 7 |
|
|
Configure bothside to be 1000BaseX Mode
|
| 8 |
|
|
|
| 9 |
|
|
Remarks :
|
| 10 |
|
|
There seems to be a bug in Altera's core, tx path
|
| 11 |
|
|
- The Tx Path sometime omits 1 pre-ample octet depending on the cycle that TxEN is aserted.
|
| 12 |
|
|
- At the transmit task, the #8 delay will have effect on the Altera's core. Without delay,
|
| 13 |
|
|
the first packet is transmitted with the first octet somehow removed (you can confirm this
|
| 14 |
|
|
by looking at the Codegroup that is input of u0SGMII/u0Receive/
|
| 15 |
|
|
- With the delay on, the first packet is fine, but the second packet has some problem.
|
| 16 |
|
|
- This has something todo with the alignment of the TxEN,
|
| 17 |
|
|
I'm not sure whether the MAC layer is responsible for aligning TxEN's assertion or not.
|
| 18 |
|
|
- This test only Transmits normal frame, i.e no Carrier Extension or Error Propagation
|
| 19 |
|
|
|
| 20 |
|
|
- The Path of U0 --> U1 is ok.
