ILA.1

Check whether the initial frame synchronization state machine enters FS_DATA state upon receiving non /K/ characters.

The following signals in <ip_variant_name>_inst_phy.v are tapped:

• jesd204_rx_pcs_data[(L*32)-1:0]
• jesd204_rx_pcs_data_valid[L-1:0]
• jesd204_rx_pcs_kchar_data[(L*4)-1:0] ²

The following signals in <ip_variant_name>.v are tapped:

• rx_dev_sync_n
• jesd204_rx_int

The rxlink_clk is used as the SignalTap II sampling clock.

Each lane is represented by 32-bit data bus in jesd204_rx_pcs_data. The 32-bit data bus is divided into 4 octets.

• /R/ character or K28.0 (0x1C) is observed after /K/ character at the jesd204_rx_pcs_data bus.
• The jesd204_rx_pcs_data_valid signal must be asserted to indicate that data from the PCS is valid.
• The rx_dev_sync_n and jesd204_rx_int signals are deasserted.
• Each multiframe in ILAS phase ends with /A/ character or K28.3 (0x7C).
• The jesd204_rx_pcs_kchar_data signal is asserted whenever control characters like /K/, /R/, /Q/ or /A/ characters are observed.

ILA.2

Check the JESD204B configuration parameters from ADC in second multiframe.

The following signals in <ip_variant_name>_inst_phy.v are tapped:

• jesd204_rx_pcs_data[(L*32)-1:0]
• jesd204_rx_pcs_data_valid[L-1:0] ²

The following signal in <ip_variant_name>.v is tapped:

• jesd204_rx_int

The rxlink_clk is used as the SignalTap II sampling clock.

The system console accesses the following registers:

• ilas_octet0
• ilas_octet1
• ilas_octet2
• ilas_octet3

The content of 14 configuration octets in the second multiframe is stored in these 32-bit registers—ilas_octet0, ilas_octet1, ilas_octet2, and ilas_octet3.

• /R/ character is followed by /Q/ character or K28.4 (0x9C) at the beginning of second multiframe.
• The jesd204_rx_int signal is deasserted if there is no error.
• Octets 0–13 read from these registers match with the JESD204B parameters in each test setup.

ILA.3

Check the lane alignment

The following signals in <ip_variant_name>_inst_phy.v are tapped:

• jesd204_rx_pcs_data[(L*32)-1:0]
• jesd204_rx_pcs_data_valid[L-1:0] ²

The following signals in <ip_variant_name>.v are tapped:

• rx_somf[3:0]
• dev_lane_aligned
• jesd204_rx_int

The rxlink_clk is used as the SignalTap II sampling clock.

• The dev_lane_aligned signal is asserted upon the last /A/ character of the ILAS is received, which is followed by the first data octet.
• The rx_somf signal marks the start of multiframe in user data phase.
• The jesd204_rx_int signal is deasserted if there is no error.
