6.6.4.5.2. Tx Path
This tab allows you to monitor the transmitter settings for the channel selected.
Group | Parameters | Values | Descriptions |
---|---|---|---|
Tx Status | Tx Electrical Idle | True False |
Indicates if TX is in electrical idle. True: indicates TX is in electrical idle. False: indicates TX is out of electrical idle. |
Tx PLL Lock | Green Red |
Indicates if TX PLL is locked.
Note: The status of the Tx PLL Lock may not be reflected properly by the Debug Toolkit in the Quartus® Prime software version 22.4. The fix for this problem is planned for a future release of the Debug Toolkit.
|
|
Tx Equalization | Tx Equalization Status | Not attempted Completed Unsuccessful |
Indicates transmitter equalization status. The TX local and remote parameters are valid only when the value of the Equalization status is returned as completed, indicating equalization has completed successfully. |
Tx Local Preset | 0 - 10 | Indicates the R-Tile transmitter driver preset value as requested by the link partner during the Equalization phase of link training. If the preset is not one of these values, then no value is shown. | |
Local Preshoot Coefficient | Depends on the coefficient requested by the link partner. | Indicates transmitter driver output pre-emphasis (pre-cursor coefficient value). | |
Local Main Coefficient | Indicates transmitter driver output pre-emphasis (main cursor coefficient value). | ||
Local Post Coefficient | Indicates transmitter driver output pre-emphasis (post-cursor coefficient value). | ||
Remote Preshoot Coefficient | Depends on the transmitter driver output of the link partner. | Indicates link partner's transmitter driver's output pre-cursor coefficient value | |
Remote Main Coefficient | Indicates link partner's transmitter driver's output main coefficient value | ||
Remote Post Coefficient | Indicates link partner's transmitter driver's output post-cursor coefficient value | ||
Remote Full Swing (fs) | Depends on the device capability of the link partner. | Indicates the full swing value used by the link partner during the Equalization phase of link training. | |
Remote Low Frequency (lf) | Indicates the low frequency value used by the link partner during the Equalization phase of link training. |
