Supported Modes
The Supported modes parameter allows you to specify which of the 1x, 2x, and 4x
modes of operation this RapidIO II IP core supports. All RapidIO II IP core variations
support 1x mode. The RapidIO II MegaCore function initially attempts link
initialization in the maximum number of lanes that the variation supports. The IP core
supports fallback to lower numbers of ports.
Maximum Baud Rate
Maximum baud rate
defines the maximum supported baud rate. The RapidIO II IP
core does not support automatic baud rate discovery.
shows the baud rates supported by the RapidIO II IP core for each device
family. A device family may include devices at speed grades that do not support all
the indicated baud rates. For information about the speed grades the RapidIO II IP
core supports for each device family, RapidIO mode, and baud rate combination, refer
to
Reference Clock Frequency
Reference clock frequency
defines the frequency of the reference clock for your
RapidIO II IP core internal transceiver. The RapidIO II parameter editor allows you to
select any frequency supported by the transceiver.
For more information about the reference clock in high-speed transceiver blocks, and
the supported frequencies, refer to
“Clocking and Reset Structure” on page 4–3
.
Enable Transceiver Dynamic Reconfiguration
The Enable transceiver dynamic reconfiguration parameter allows you to specify
whether or not the Arria 10 Native PHY IP core dynamic reconfiguration interface is
available in the visible signals of the RapidIO II IP core. If you do not expect to use
this interface, you can turn off this parameter to lower the number of IP core signals to
route.
This parameter is available only in IP core variations that target an Arria 10 device.
