Serial RapidIO mode provides the non-bonded (×1) transceiver channel datapath
configuration for SRIO protocol implementation. The Cyclone IV GX transceiver
provides the PMA and the following PCS functions:

Cyclone IV GX transceivers do not have built-in support for some PCS functions such
as pseudo-random idle sequence generation and lane alignment in ×4 bonded
channel configuration. If required, you must implement these functions in a user
logics or external circuits.
The RapidIO Trade Association defines a high-performance, packet-switched
interconnect standard to pass data and control information between microprocessors,
digital signals, communications, network processes, system memories, and peripheral
devices. The SRIO physical layer specification defines serial protocol running at
1.25 Gbps, 2.5 Gbps, and 3.125 Gbps in either single-lane (×1) or bonded four-lane (×4)
at each line rate. Cyclone IV GX transceivers support single-lane (×1) configuration at
all three line rates. Four ×1 channels configured in Serial RapidIO mode can be
instantiated to achieve one non-bonded ×4 SRIO link. When implementing four ×1
SRIO channels, the receivers do not have lane alignment or deskew capability.
