Document Table of Contents Merging PLLs and Transceivers (GXB)

Multiple instances of the ALTPLL IP core can use the same PLL resource on the device. Similarly, GXB transceiver instances can share high-speed serial interface (HSSI) resources in the same quad as other instances. The Fitter can merge multiple instantiations of these blocks into the same device resource, even if it requires optimization across partitions. Therefore, there are no restrictions for PLLs and 
high-speed transceiver blocks when setting up partitions.
