CustomLogic is an FPGA design kit enabling the design and upload of FPGA code to a Coaxlink board. It is compatible with the Coaxlink Octo, Coaxlink Quad CXP-12 and Coaxlink QSFP+. Typ. up to 70% of their Xilinx Kintex Ultrascale XCKU035 FPGA logic available. The design phase uses the Xilinx Vivado development tools (available free of charge from AMD-Xilinx).

e.g. Resources available to the user of a Coaxlink Quad CXP-12 (1-camera, custom logic) firmware variant. Figures may vary for different firmware variants.
For PC3625 Coaxlink QSFP+ only: A specific IP License is required and obtainable from AMD. Contact our support for more information.

The Data Stream interface is based on the AMBA AXI4-Stream protocol. On the source side, this interface provides the user logic with images acquired from a CoaXPress Device (for example a CoaXPress camera). On the destination side, the Data Stream interface transfers the resulting images/data generated by the user logic to the PCI Express DMA Back-End channel.

The DDR4 Memory interface is based on the AMBA AXI4 protocol.

The Memento Event interface allows the User Logic to send timestamped events to the Memento Logging tool with a precision of 1 μs. Along with the timestamped event, two 32-bit arguments are reported in Memento.

The Control/Status interface allows the user to read and write registers inside the user logic via the Coaxlink Driver API.

The Coaxlink CustomLogic SDK is delivered with a reference design intended to be used as a template. The reference design exposes all interfaces available to the user. It is a AMD Vivado project with the following functional block diagram:

Using CustomLogic does not require any additional hardware. The 3613 JTAG Adapter AMD for Coaxlink (available free of charge from AMD) allows connecting the AMD programmer to the Coaxlink FPGA for debugging purposes.
