4.4. Clock Connections for CvP Designs Including the Transceiver Reconfiguration Controller

If your design includes the following components:
  • An Arria V, Cyclone V, or Stratix V device with CvP enabled
  • Any additional transceiver PHY connected to the same Transceiver Reconfiguration Controller
then you must connect the PLL reference clock which is called refclk to the mgmt_clk_clk signal of the Transceiver Reconfiguration Controller and the additional transceiver PHY. In addition, if your design includes more than one Transceiver Reconfiguration Controllers on the same side of the FPGA, these controllers all must share the mgmt_clk_clk signal.
Note:
  • For Stratix V and Arria V GZ devices, when CvP is enabled you cannot use dynamic transceiver reconfiguration for the transceiver channels in CvP-enabled Hard IP until after the core is loaded.
  • For Cyclone V and Arria V devices, when CvP is enabled in PCIe Gen1 mode, you cannot use dynamic transceiver reconfiguration for the transceiver channels in CvP-enabled Hard IP until after the core is loaded.
