What would experts here recommend for simulating 5ghz and 10ghz USB 3 on a particular gerber file and layup?<p>I've been avoiding it and spinning boards making small changes hoping for the best but still having issues. And don't have the resources to buy a scope capable of doing an eye diagram at 10ghz<p>Also bonus question.. How good are the simulations? Am I likely to be able to iterate on my layout and improve the eye diagram and order boards which have a good chance of working?
