The section describes the combination requirements for an instance that is configured
in one of the three options mentioned above with other instances.
If you create a transceiver instance by selecting the use alternate CMU PLL option,
the Quartus II software uses two CMU PLLs. If you intend to combine other
transmitter instances within the same transceiver block, the CMU PLLs must be
shared between multiple instances. To enable the Quartus II software to share the
CMU PLLs between these instances, you must:
1. Select the user alternate CMU PLL option in all the instances.
2. Set the same PLL logical reference index value for the similar PLLs between the
