JESD204B IP catalog implementation for project

[hari_kethavath]

Hey community members, I am hari a master's student working on High speed data transmission based on jesd204b protocol project, I'm exploring how to implement this using intel quartus IP core.

seeking guidance on

•  how to implement jesd204b IP core
•  simulation steps.

Best

Hi Hari, 

You may follow these steps, hope that helps. 

1. JESD204B IP Core Implementation (Intel Quartus)

Step 1: Open Quartus and Create a New Project

• Launch Intel Quartus Prime.
• Create a new project specifying your FPGA device.

Step 2: Add JESD204B IP Core

• Go to Tools > IP Catalog.
• Search for JESD204B.
• Double-click to open the IP customization wizard.

Step 3: Configure the IP Core

• Set Parameters:
  • Select Transmitter (TX) or Receiver (RX).
  • Set lane count, link width, octets per frame, frames per multiframe, etc.
  • Choose your device family and speed grade.
• Clocks & Resets:
  • Assign reference clock frequency.
  • Set up reset signals.
• Physical Layer:
  • Configure transceiver settings (e.g., data rate, encoding).
• AXI Interface (if available):
  • Configure the AXI or Avalon-MM interface as per your design needs.

Step 4: Generate HDL Files

• Click Generate HDL (Verilog or VHDL).
• The wizard will create:
  • IP core files (jesd204b_xxx.v or .vhd)
  • Example instantiation files
  • Simulation models

Step 5: Instantiate the IP Core

• In your top-level HDL file, instantiate the JESD204B IP core.
• Connect:
  • Data input/output ports
  • Clock and reset signals
  • Control/status interfaces

Step 6: Synthesize and Compile

• Add all HDL files to your Quartus project.
• Compile the project to ensure there are no errors.

2. Simulation Steps

Step 1: Prepare the Testbench

• Use the example testbench provided by the IP wizard, or create your own.
• The testbench should:
  • Generate clocks and resets
  • Provide stimulus to data input ports (TX)
  • Monitor output ports (RX)
  • Check for link initialization, correct frame transmission, and error flags

Step 2: Add JESD204B Simulation Model

• Use the simulation models generated by the IP wizard.
• Include all necessary libraries in your simulation tool (e.g., ModelSim, QuestaSim).

Step 3: Simulate Link Initialization

• Ensure the testbench resets the core, then applies valid configuration signals.
• Check that the link transitions through CGS (Code Group Synchronization), ILAS (Initial Lane Alignment Sequence), and data transmission stages.

Step 4: Simulate Data Transfer

• Apply sample data at the transmitter input.
• Observe data at the receiver output.
• Check for error flags and status signals.

Step 5: Monitor JESD204B Status

• Monitor status ports (e.g., link up, lane up, error) for correct operation.
• Use waveform viewer to trace key signals.

Step 6: Debug and Validate

• If issues arise, check:
  • Clock frequencies
  • Lane configuration
  • Data alignment
  • IP core parameters
