You can configure the Stratix IV device in ×1, ×4, and ×8 PCIe configurations. The
reset sequence described in
multi-lane configurations.
Stratix IV devices provide a PMA Direct mode in which all PCS blocks, including the
phase compensation FIFOs, are bypassed in both the transmitter and receiver channel
data paths. In this mode, the PMA block in the transmitter and receiver channels
directly interface with the FPGA fabric.
In PMA Direct drive mode, you can configure the transceiver channels as a single
channel or in bonded configurations. Basic single- and double-width functional
modes support bonding of PMA functional blocks across all transceiver channels on
the same side of the device.
The tx_digitalreset and rx_digitalreset signals are not available because there
are no PCS blocks available in this mode.
