You couldn't be any more dead-on. EDA feels like Scientology, where with every level closer to the core you first need to invest half your life savings + a firstborn. I have an FPGA lying on my desk I can do barely anything interesting with because there are no open-source cores for even simple things like USB3.1 controllers or Thunderbolt or pretty much any interesting bus. Protocols are strongly guarded open secret…
USB 3.1 pushes data at 10Gbps. Do you have any idea how much black magic it takes to do that? Try writing an FPGA SDRAM controller that reliably operates across frequency, voltage, and temperature at 150 MHz. It is doable but a challenge with the common xilinx boards that are sold to hobbyists for $80. If you can do that, then think about designing a circuit which operates 20 times faster, and negotiates a protocol w…
Kernels are extremely complex software blobs with crazy race conditions, and tons of device-specific hacks. Somehow the world goes on with Linux going open source. Nobody is claiming that a single person will bang out a USB 3.1 block, but building up these "IP"s over time through the community would be a huge first step.
