PCIe System Parameters
PHY type (1)
Custom
Allows all types of external PHY interfaces (except serial). The number of
lanes can be ×1 or ×4. This option is only available for the soft IP
implementation.
Stratix II GX
Serial interface where Stratix II GX uses the Stratix II GX device family's
built-in transceiver. Selecting this PHY allows only a serial PHY interface
with the lane configuration set to Gen1 ×1, ×4, or ×8.
Stratix IV GX
Serial interface where Stratix IV GX uses the Stratix IV GX device
family's built-in transceiver to support PCI Express Gen1 and Gen2 ×1,
×4, and ×8. For designs that may target HardCopy IV GX, the
HardCopy IV GX setting must be used even when initially compiling for
Stratix IV GX devices. This procedure ensures that you only apply
HardCopy IV GX compatible settings in the Stratix IV GX
implementation.
Cyclone IV GX
Serial interface where Cyclone IV GX uses the Cyclone IV GX device
family’s built-in transceiver. Selecting this PHY allows only a serial PHY
interface with the lane configuration set to Gen1 ×1, ×2, or ×4.
HardCopy IV GX
Serial interface where HardCopy IV GX uses the HardCopy IV GX device
family's built-in transceiver to support PCI Express Gen1 and Gen2 ×1,
×4, and ×8. For designs that may target HardCopy IV GX, the
HardCopy IV GX setting must be used even when initially compiling for
Stratix IV GX devices. This procedure ensures HardCopy IV GX
compatible settings in the Stratix IV GX implementation. For Gen2 ×8
variations, this procedure will set the RX Buffer and Retry Buffer to be
only 8 KBytes which is the HardCopy IV GX compatible implementation.
Arria GX
Serial interface where Arria GX uses the Arria GX device family’s built-in
transceiver. Selecting this PHY allows only a serial PHY interface with
the lane configuration set to Gen1 ×1 or ×4.
Arria II GX
Serial interface where Arria II GX uses the Arria II GX device family's
built-in transceiver to support PCI Express Gen1 ×1, ×4, and ×8.
Arria II GZ
Serial interface where Arria II GZ uses the Arria II GZ device family's
built-in transceiver to support PCI Express Gen1 ×1, ×4, and ×8, Gen2
×1, Gen2 ×4.
TI XIO1100
TI XIO1100 uses an 8-bit DDR/SDR with a TXClk or a 16-bit SDR with a
transmit clock PHY interface. Both of these options restrict the number
of lanes to ×1. This option is only available for the soft IP
implementation.
NXP PX1011A
Philips NPX1011A uses an 8-bit SDR with a TXClk and a PHY interface.
This option restricts the number of lanes to ×1. This option is only
available for the soft IP implementation.
