Critical Issue
The 40- and 100-Gbps Ethernet MAC and PHY MegaCore Function User Guide states that the 40-100GbE IP core pause control and generation signals are unavailable in IP core variations with adapters.
However, these signals are available in 40-100GbE IP core variations with and without adapters in the Quartus II software release 12.0 and all later releases.
For information about the pause signals in IP core variations with adapters, refer to the signal descriptions for variations without adapters.
This issue is fixed in version 14.1 of the 40- and 100-Gbps Ethernet MAC and PHY MegaCore Function User Guide.
