I have checked out code from https://github.com/analogdevicesinc/hdl. I am using branch hdl_2017_r1. In the file library/jesd204/README.md the license terms are described. In that file, analog devices claims to have a non-GPL license available, if you email firstname.lastname@example.org However, when I email that address, it gets returned non-deliverable. What is the proper channel for obtaining the desired license?
