Transceiver Selection
The Transceiver selection parameter value is determined by the device family your IP
core targets.Although this parameter appears in the parameter editor, you cannot
modify its value.
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 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.
Synchronizing Transmitted ackID
The Automatically synchronize transmitted ackID option turns on support for using
an initial ackID value specified by the RapidIO link partner. If the ackID value in the
first seven status control symbols it receives on the link are identical, the RapidIO IP
core uses this value as the starting ackID value for packets it transmits. If this option is
turned off, the starting ackID value is 0.
This parameter is not available for variations that target an Arria 10 device. In Arria
10 variations, this option is turned on internally and cannot be modified.
Sending Link-Request Reset-Device on Fatal Errors
The Send link-request reset-device on fatal errors option specifies that if the
RapidIO IP core identifies a fatal error, it transmits four link-request control symbols
with cmd set to reset-device on the RapidIO link. By default, this option is turned off.
The option is available for backward compatibility, because previous releases of the
RapidIO IP core implement this behavior.
Number of Link-Request Attempts Before Declaring Fatal Error
The Link-request attempts parameter allows you to specify the number of times the
RapidIO IP core sends a link-request reset-device control symbol following a
link-request
time-out, before declaring a fatal error. This parameter can have values
1 through 7. The default value in a new variation is 7.
This parameter is not available for variations that target an Arria 10 device. In Arria
10 variations, this parameter is set internally to the value 7 and cannot be modified.
