Figure 1–49. Transceiver Configuration in PIPE Mode
When configuring the transceiver into PIPE mode using ALTGX megafunction for
PCIe implementation, the PHY-MAC, data link and transaction layers must be
implemented in user logics. The PCIe hard IP block is bypassed in this configuration.
PIPE Interface
The PIPE interface provides a standard interface between the PCIe-compliant PHY
and MAC layer as defined by the version 2.00 of the PIPE Architecture specification
for Gen1 (2.5 Gbps) signaling rate. Any core or IP implementing the PHY MAC, data
link, and transaction layers that supports PIPE 2.00 can be connected to the
Cyclone IV GX transceiver configured in PIPE mode.
