Description
Quartus® II 10.1 and 10.1 SP1 software incorrectly allows you to select the RX Bitslip option. Receive Bitslip option is not supported in Low Latency PHY IP for Stratix® V GX devices. This option should not be selectable in IP Megawizard™ flow.
This issue will be fixed in future Quartus II software versions.
