| Signal Name |
Location ( Arria® 10, Cyclone® 10 GX, Stratix® V, and Arria® V GZ) |
Location ( Stratix® 10) |
Description |
|---|---|---|---|
| rx_aligned | Top level port |
Top level port |
This active high signal indicates that the lanes are properly aligned. This signal should remain asserted for proper operation. |
| rx_pcs_ready | Native PHY wrapper port |
(Encrypted) Soft PHY port |
An asserted value for this active high signal indicates that the reset sequence for the sink PCS is complete. |
| rx_crc32err | Native PHY wrapper port |
PHY top internal |
This active high signal indicates CRC-32 error from the CRC checker. |
| rx_pcs_err | _ | PHY top port |
This active high signal indicates if there is any Sync Header, Meta-frame Length, or CRC32 error. This signal can be used to debug whether there is any data integrity issue on a given meta-frame. |
| rx_frame_lock [lanes-1:0] | Native PHY wrapper port |
PHY top internal |
This active high signal indicates that four Interlaken synchronization words are found for a given lane. |
| rx_block_frame_lock | Native PHY wrapper port |
PHY top port | This active high signal indicates whether a link has established both block lock and frame lock link alignment state. |
| rx_is_lockedtodata [lanes-1:0] | Native PHY wrapper internal |
PHY top internal |
This active high signal indicates that the transceiver channel PLL has locked itself to the incoming data. |
| rx_cal_busy | Native PHY wrapper internal |
PHY top internal |
Sink transceiver calibration status. This active high signal can be used for debugging if the reconfiguration controller is actively calibrating during the initialization sequence. |
