Parameter Description |
---|---|---|---|
Mode selection | |||
Enable auto-negotiation on reset |
|
On | Enable Auto-negotiation. |
Enable link training on reset |
|
On | Enable Link Training. |
Enable ECC protection |
|
Off | Enable Error Correction Code (ECC) for Nios® II memory. To enable this feature, you must acquire Nios® II license. Contact Intel Sales for information about acquiring a license. |
PMA type |
|
FGT | PMA Type. Selects the PMA type. Each PMA has a different data rate range and compliance specifications. The selected mode must match with PMA mode selected in Base IP. |
Ethernet mode |
|
10GE-1 | Ethernet Configuration. Specifies the overall port bandwidth across the number of physical lanes used by the port. Term XGbE-Y represents:
The selected mode must match with Ethernet mode selected in Base IP. |
KR or CR mode |
|
CR mode | Selects the option during auto-negotiation. |
Number of ports | 1-16 | 4 | Selects number of base Ethernet IP ports connected to the IP. |
FEC mode |
|
None | Selects the FEC mode for each port.
The IP core supports the following FEC types
|
Link fail inhibit time | 0-20000 |
|
Sets the link fail inhibit timeout for auto-negotiation in milliseconds.
Default value:
|
Status clock frequency | 100-250 | 100 | Selects the auto-negotiation and link training status clock frequency. Must be set to the frequency of the i_clk input for the correct timer functionality. |
AN Channel Map |
|||
AN channel |
|||
AN channel location <n> |
0-7 | 0 |
Selects the AN lane default location in each Ethernet ports. <n> is an integer from 0 to (number of lanes - 1). For example, for 100GE-4, AN channel location <n> parameter can be 0 to 3. This option is not available for single lane (For example, 10GE-1, 25GE-1). |
