OFS Agilex 7 PCIe Attach FPGA Development Directory

This is the OFS Agilex 7 PCIe Attach FPGA development top-level directory. This repository supports targetting the same design to multiple board configurations specified in syn/board/<board_name> folder.

Board

• n6001

  • Default .ip parameters are based on n6001 design

      ./ofs-common/scripts/common/syn/build_top.sh -p --ofss tools/ofss_config/n6001.ofss,tools/ofss_config/hssi/hssi_8x25.ofss n6001 work_n6001

  • Additionally, n6001 fim supports reconfiguring the .ip via .ofss flow. For example to change hssi config, pass the .ofss files below.

      # n6001 with 2x100G 
      ./ofs-common/scripts/common/syn/build_top.sh -p --ofss tools/ofss_config/n6001_base.ofss,tools/ofss_config/hssi/hssi_2x100.ofss n6001 work_n6001_2x100
  
      # n6001 with 8x10G 
      ./ofs-common/scripts/common/syn/build_top.sh -p --ofss tools/ofss_config/n6001_base.ofss,tools/ofss_config/hssi/hssi_8x10.ofss n6001 work_n6001_8x10

• Contains the license setup software for the version of Quartus used for this distribution/release.

OFS Common Content Directory (Link to top-level directory ofs-common)

• Contains the scripts, source code, and verification environment resources that are common to all of the repositories.
• This directory is referenced via a link within each of the FPGA-Specific repositories.

Simulation

• Contains the testbenches and supporting code for all of the unit test simulations.
  • Bus Functional Model code is contained here.
  • Scripts are included for automating a myriad of tasks.
  • All of the individual unit tests and their supporting code is also located here.

FPGA Interface Module (FIM) Source code (src)

• This directory contains all of the structural and behavioral code for the FIM.
• Also included are scripts for generating the AXI buses for module interconnect.
• Top-level RTL for synthesis is located in this directory.
• Accelerated Functional Unit (AFU) infrastructure code is contained in this directory.

FPGA Synthesis

• This directory contains all of the scripts, settings, and setup files for running synthesis on the FIM.
