Dynamic Reconfiguration
As silicon progresses towards smaller process nodes, circuit performance is affected
more by variations due to process, voltage, and temperature (PVT). These process
variations result in analog voltages that can be offset from required ranges. The
calibration performed by the dynamic reconfiguration interface compensates for
variations due to PVT.
For non-bonded clocks, each channel and each TX PLL has a separate dynamic
reconfiguration interfaces. The MegaWizard Plug-In Manager provides informational
messages on the connectivity of these interfaces. Example 15–4 shows the messages
for the Cyclone V Native PHY with four duplex channels, four TX PLLs, in a
non-bonded configuration.
For more information about transceiver reconfiguration refer to Transceiver
Reconfiguration Controller IP Core.
Simulation Support
The Quartus II 12.1 release provides simulation and compilation support for the
Cyclone V Native PHY IP Core. Refer to Running a Simulation Testbench for a
description of the directories and files that the Quartus II software creates
automatically when you generate your Cyclone V Transceiver Native PHY IP Core.
Example 15–4. Informational Messages for the Transceiver Reconfiguration Interface
PHY IP will require 8 reconfiguration interfaces for connection to the external
reconfiguration controller.
Reconfiguration interface offsets 0-3 are connected to the transceiver channels.
Reconfiguration interface offsets 4–7 are connected to the transmit PLLs.
