3.3. Configuring and Generating GTS System PLL Clocks Intel® FPGA IP

Followig is the pocedue to geeate the GTS System PLL Clocks Itel® FPGA IP.

  1. Select GTS System PLL Clocks Itel® FPGA IP i the IP Catalog
  2. A New IP Vaiat widow appeas. Specify a top-level ame fo you ew custom IP vaiatio. The paamete edito saves the IP vaiatio settigs i a file amed <you_ip>.ip.
  3. Click Ceate. The paamete edito appeas. Set the paametes as show i the followig table.
  4. Geeate the GTS System PLL Clocks Itel® FPGA IP.
    1. Click Geeate HDL.
    2. A Geeatio dialog box appeas fom the pevious step. This allows you to geeate a System PLL IP.
    3. Specify output file geeatio optios, ad the click Geeate. The IP vaiatio files ae geeated accodig to you specificatios.
    4. Click Close. The paamete edito adds the top-level.ip file to the cuet poject automatically. If you ae pompted to maually add the .ip file to the poject, click Poject > Add/Remove Files i Poject to add the file.

Select the settig that match the PLD clock fequecy i the GTS AXI Steamig IP.

  • PCIe* 4.0 x8: PCIE_FREQ_500/PCIE_FREQ_450/PCIE_FREQ_400/PCIE_FREQ_350//PCIE_FREQ_300/PCIE_FREQ_250/Use_PCIE-based_Cofiguatio_200.
  • PCIe* 4.0 x4: PCIE_FREQ_350/PCIE_FREQ_300/PCIE_FREQ_250/Use_PCIE-based_Cofiguatio_200.
  • PCIe* 3.0 x8: PCIE_FREQ_350//PCIE_FREQ_300/PCIE_FREQ_250/Use_PCIE-based_Cofiguatio_200.
  • PCIe* 4.0 x2/x1, PCIe* 3.0 x4/x2/x1: PCIE_FREQ_300/PCIE_FREQ_250/Use_PCIE-based_Cofiguatio_200.
Output fequecy C0 Automatically set based o the Mode of System PLL settig.
Refclk fequecy 100 MHz
Note:
  1. Refe to Implemetig the GTS System PLL Clocks Itel® FPGA IP sectio i the GTS Tasceive PHY Use Guide .
  2. PCIE_FREQ_300 deotes the PLD clock fequecy of 300 MHz. This fequecy eeds to match the PLD clock fequecy settig i the GTS AXI Steamig IP.
  3. The Use_PCIE-based_Cofiguatio_200 meas to set Mode of System PLL to "Use PCIe* -based Cofiguatio" ad Output fequecy C0 to "200" i the GTS System PLL Clocks Itel® FPGA IP paamete edito GUI. This is eeded whe PLD clock fequecy settig i the GTS AXI Steamig IP is set to 200 MHz.
