GXB_CLOCK_GROUP
Specifies GXB core clock groups to be merged after compilation. All specified GXB transmitters in the
GXB shared clock group are driven by the clock source specified in the GXB shared clock group driver.
All clocks in the GXB shared clock group and GXB clock group driver must be configured in the same
manner. When the destination GXB transmitter is listening to a signal such as gxb_powerdown, disable
the GXB shared clock group driver source. Follow the Altera High Speed I/O Applications Technical
Support recommendations when using this assignment.
