System Settings
PCIe* 0 Hard IP Mode
  • Gen4x4 Interface 256 bit
  • Gen4x2 Interface 128 bit
  • Gen4x1 Interface 128 bit
  • Gen3x4 Interface 128 bit
  • Gen3x2 Interface 128 bit
  • Gen3x1 Interface 128 bit
  • Disabled

Gen3 x4 Interface 128 bit

Selects the width of the data interface between the transaction layer and the application layer implemented in the PLD fabric, the lane data rate, and the lane rate.

PCIe* 1 Hard IP Mode
  • Gen4x8 Interface 512 bit
  • Gen3x8 Interface 256 bit
  • Disabled
Disabled Selects the width of the data interface between the transaction layer and the application layer implemented in the PLD fabric, the lane data rate, and the lane rate. The Gen4x8 and Gen3x8 options are available when PCIe* 0 Hard IP Mode is set to Disabled.
Note: This option is only available in the D-Series FPGAs.
PCIe* 0 Enable TLP-bypass mode
  • True
  • False
False

Enables the TLP Bypass feature for PCIe* 0.

PCIe* 1 Enable TLP-bypass mode
  • True
  • False
False
Enables the TLP Bypass feature for PCIe* 1.
Note: This option is only available in the D-Series FPGAs.
PCIe* 0 Port Mode
When you set Enable TLP-bypass mode to false, the following values are available:
  • Root Port
  • Native Endpoint
Native Endpoint

Selects the port mode for PCIe* 0.

When you set Enable TLP-bypass mode to true, the following values are available:
  • Downstream Port
  • Upstream Port
Upstream Port
PCIe* 1 Port Mode
When you set Enable TLP-bypass mode to false, the following values are available:
  • Root Port
  • Native Endpoint
Native Endpoint
Selects the port mode for PCIe* 1.
Note: This option is only available in the D-Series FPGAs.
When you set Enable TLP-bypass mode to true, the following values are available:
  • Downstream Port
  • Upstream Port
Upstream Port
PLD Clock Frequency
  • 500 MHz
  • 450 MHz
  • 400 MHz
  • 350 MHz
  • 300 MHz
  • 250 MHz
  • 200 MHz
300 MHz

Selects the PLD clock frequency.

Note:
  1. Select the optimum PLD clock frequency to achieve maximum bandwidth. Refer to the Simple Packing Data Width and Optimum PLD Clock Frequency table for more details on the PLD clock frequencies.
  2. Higher than the optimum PLD clock frequency is allowed for some of the Hard IP modes above provided that the timing requirements can be met.
Enable SRIS Mode
  • True
  • False
False

Enables the Separate Reference Clock with Independent Spread Spectrum Clocking (SRIS) feature.

Enable PIPE Mode Simulation
  • True
  • False
False

When selected, the PIPE mode simulation is enabled.

Note: This parameter is not supported for Quartus® Prime compilation.

The PIPE mode simulation is not supported for Questa* Intel® FPGA Edition.

When running simulations with this parameter enabled, the following macro is required with the FASTSIM mode enabled: "+define+SM_PIPE_MODE"

Enable CVP (Intel VSEC)
  • True
  • False
False Enables CvP for the device.
