Check whether sync request is deasserted after correct reception of four successive /K/ characters. |
The following signals in <ip_variant_name> _inst_phy.v are tapped:
The following signals in <ip_variant_name> .v are tapped:
The rxlink_clk signal is used as the SignalTap II sampling clock. Each lane is represented by a 32-bit data bus in the jesd204_rx_pcs_data signal. The 32-bit data bus is divided into 4 octets. |

CGS.2 |
Check full CGS at the receiver after correct reception of another four 8B/10B characters. |
The following signals in <ip_variant_name> _inst_phy.v are tapped:
The following signal in <ip_variant_name> .v is tapped:
The rxlink_clk signal is used as the SignalTap II sampling clock. |
The jesd204_rx_pcs_errdetect, jesd204_rx_pcs_disperr, and jesd204_rx_int signals should not be asserted during CGS phase. |
