3.1. Installing and Licensing Intel® FPGA IP Cores

The Quartus® Prime software installation includes the Intel® FPGA IP library. This library provides many useful IP cores for your production use without the need for an additional license. Some Intel® FPGA IP cores require purchase of a separate license for production use. The Intel® FPGA IP Evaluation Mode allows you to evaluate these licensed Intel® FPGA IP cores in simulation and hardware, before deciding to purchase a full production IP core license. You only need to purchase a full production license for licensed Intel® IP cores after you complete hardware testing and are ready to use the IP in production.

The Quartus® Prime software installs IP cores in the following locations by default:
