For real eye diagram, a signal / PRBS generator and a high end oscilloscope. Those are in the many-tens-of-thousands of USD range.
Debug tools for eg. FPGA transceivers or some redriver chips can measure BER and show fake eye diagrams. In the few-hundreds to the few-thousands of USD range, but you may need a company to sing NDAs. Eg.:
