Aurora 8B10B v11.0Rev2 or later - UltraScale - RXLPMEN needs to be set to enable LPM

Description

When "Additional transceiver control and status ports" is selected while generating the core, RXLPMEN is made available at the core interface.

Because the default equalizer in Aurora 8B10B is LPM, the RXLPMEN port needs to be tied to 1'b1.

Solution

In the 2015.3 release, Aurora 8B10B ties RXLPMEN to 1'b0 at the example design level when the "Additional transceiver control and status ports" option is selected while generating the core. 

This sets DFE to be enabled with the core.

This issue will be fixed in the VIVADO 2016.1 release.
