About the Core

The SPI-4.2 core is a Xilinx CORE Generator™ IP core, included in the latest IP update on the Xilinx IP Center. For detailed information about the core, see the SPI-4.2 product page. For information about system requirements, installation, and licensing options, see Chapter 2, “Licensing the Core.”

Recommended Design Experience

Although the SPI-4.2 core is a fully verified solution, the challenge associated with implementing a complete design varies, depending on desired configuration and functionality. For best results, previous experience building high-performance, pipelined FPGA designs using Xilinx implementation software and user constraints files (UCF) is recommended.
