3.1. Introduction to Intel® FPGA IP

Intel and strategic IP partners offer a broad portfolio of configurable IPs optimized for Intel FPGA devices.

The Quartus® Prime software installation includes the Intel® FPGA IP library. Integrate optimized and verified Intel® FPGA IPs into your design to shorten design cycles and maximize performance. The Quartus® Prime software also supports integration of IPs from other sources. Use the IP Catalog (Tools > IP Catalog) to efficiently parameterize and generate synthesis and simulation files for your custom IP variation. The Intel® FPGA IP library includes the following types of IPs:

Basic Functions Interface Protocols
Bridges and adapters Low power functions
DSP functions Memory interfaces and controllers
Intel FPGA Interconnect Processors and peripherals

This section provides basic information about parameterizing, generating, upgrading, and simulating stand-alone IPs in the Quartus® Prime software.
