problem in adding IP to platform designer
Here is how you can resolve most of your Intel FPGA related problems

Check for KDB or &quot;Knowledge Database&quot; on Intel website for bugs in SW / Silicon etc

Use one revision of Quartus lower than the problem version

Please include a screenshot of the problem and a better description than &quot;IP does not add to project&quot;. Are you sure you are doing everything right ? Ensure you watch the YouTube &quot;How to&quot; videos from Intel FPGA channel.
