The Aurora 64B/66B Protocol Specification v1.0 includes 64B/66B encoding schemes, full-duplex operation, and serial simplex operation. The ABFM 64B/66B models the behavior of Aurora 64B/66B protocol and can be used to generate stimulus for and to monitor the response of an Aurora 64B/66B interface design. The BFM includes advanced features for precision testing and characterization of Aurora implementations--including simplex, and corner case testing for 64B/66B designs.
