B. Sharing PLLs for Multicore Designs
This appendix explains how to share a PLL between one receiver and one transmitter
POS-PHY 4 MegaCore functions and between two transmitter cores.
Figure B–1 shows how to connect the reset and the rdclk and trefclk signals when
you share a PLL between a receiver and transmitter core.

Even though Figure B–1 shows two PLLs, the Quartus II software optimizes the PLL
instance as if it is one PLL.

To share the PLL, follow these steps:
1
The LVDS data rates must be the same for each core.
1. Create a new Quartus II project, but call the project name and the top-level entity
names different names.
2. Create your receiver core.
3. Create your transmitter core.
