You can come work with us/for us and scale your SerDes design for us. That gets you actual wafer mask sets taped-out, a million chips and a WSI, not just test chips. A succesful SerDes will get you a job (at least in Europe).

How fast will the SerDes run, 50 Mhz? It is not clear to me from the serdes_tile.dart source code. Can you share the verilog files?
