6.14. Dynamic Reconfiguration Interface Merging Across Multiple
IP Blocks
Dynamic reconfiguration interfaces may need to be shared between multiple IP blocks
to maximize transceiver channel utilization. The Native PHY provides the ability to
create channels that are either simplex or duplex instances. However, each physical
transceiver channel in Arria 10 devices is fully duplex.
You can share the reconfiguration interfaces across different IP blocks by manually
making a QSF assignment. There are two cases where a dynamic reconfiguration
interface might need to be shared between multiple IP blocks:
• Independent instances of simplex receivers and transmitters in the same physical
location
• Separate CMU PLL and TX channel in the same physical location
The following example shows one Native PHY IP instance of a TX-only channel and
another instance of an RX-only channel.
