Hello PPL,

I have a wague question. can i use the open cores code for my final product, will there be any royalty or any other issues related?

we have a requirement of using the USB 2.0 CORE, as IP CORE from Vendor is costly.

comments are invited

Thanks in advance
Pradeep Kumar

Hello Pradeep,

if you are talking about the USB2.0 core posted here at OpenCores, I opened the README file inside of the project structure and found out the project is also offered under www.asic.ws . On that page I found information about its licensing, it is a BSD modified license this is the interesting cut of it:

Redistribution and use in source, netlist, binary and silicon forms, with or without modification, are permitted provided that the following conditions are met:

So the answer is yes, you can use the core for a product, provided that you reproduce the same copyright. You have to go to the webpage and click on "Free IP cores" on the left side and then on the small iconized "i" besides BSD on the main page.

Best regards,
