mega_dualpeak_v3 - FPGA Design

FPGA design for Mega DualPeak V3 project based on Xilinx Zynq UltraScale+ ZU4CG.

Requirements

• Xilinx Vivado 2021.2
• Target device: xczu4cg-fbvb900-1-e

Building the FPGA Design

cd mega_dualpeak_v3
source ~/opt/Xilinx/Vivado/2021.2/settings64.sh
vivado -mode batch -source mega_dualpeak_v3_vivado_project.tcl

Opening in Vivado GUI

vivado project_mega_dualpeak_v3/mega_dualpeak_v3.xpr

Project Contents

• Block Design: bd/mega_dualpeak_v3-zusys.tcl - Zynq UltraScale+ system block design
• Constraints: sdc/ - XDC constraint files (pins, debug, timing)
• IP Definitions: ipdefs/ - Custom and third-party IPs including:
  • axi_lux2810 (RX channel interface)
  • axis_peak (peak detection pipeline)
  • eth_10g (10 Gigabit Ethernet MAC)
  • And various AXI stream processing blocks

mega_sw - Software Tools

Software development environment for the Zynq platform including:

• cam_control.mega_v3/: Camera control applications
• devicetree/: Device tree sources
• linux/: Linux kernel configuration and patches
• petalnx/: PetaLinux project files
• u-boot/: U-Boot bootloader
• scripts/: Build and deployment scripts
• sd_disk/: SD card disk image utilities

Prerequisites

• Linux 64-bit OS (Ubuntu 20.04 LTS recommended)
• Xilinx Vivado 2021.2 tools installed
• Install Xilinx tools in your home directory (e.g., ~/opt/Xilinx) to avoid permission issues

Build Instructions

Refer to the README.md files in each subdirectory for specific build instructions.

Notes

mega_10gbeth_ptp Design Note

Some designs in this repository are based on Xilinx 10G Ethernet PTP reference designs. These may have:

• Different QSPI partition layouts
• Custom Xilinx axienet driver with PTP support (megalodon_ptp_defconfig)
