Altera Quartus II Settings File - Manual (Page 598)

GXB_TX_PLL_RECONFIG_GROUP
Specifies whether GXB transceiver channels with Dynamic TX PLL Reconfiguration can be placed in the
same physical GXB Quad. If the GXB transceivers have 2 dynamically reconfigured TX PLLs, the GXB
transceivers are not placed into the same physical Quad when Dynamic TX PLL Reconfiguration setting is
turned ON unless they are in the same TX PLL reconfig group. If the GXB transceivers have 1
dynamically reconfigured TX PLLs, GXB transceivers from 2 TX PLL reconfig groups can be placed into
the same physical Quad if the logical number on the TX PLLs are different. GXB transceivers can be
assigned to the same group if the following conditions are met: (1) GXB transmitters in the same group
can only listen to 2 TX PLLs at one time, (2) the user must maintain proper data rates on TX PLLs
according to Altera user guidelines, (3) the user must wait for pll_locked signal asserted for dynamic PLL
reconfiguration completion, and the GXB receiver and transmitter will be kept in reset until the dynamic
reconfiguration of both is complete.
