This parameter is not available for variations that target an Arria 10 device. RapidIO
IP core Arria 10 variations that support DOORBELL messages preserve transaction order
between DOORBELL messages and I/O write request transactions.
Capability Registers Settings
The Capability Registers tab lets you set values for some of the capability registers
(CARs), which exist in every RapidIO processing element and allow an external
processing element to determine the endpoint’s capabilities through MAINTENANCE
read operations. All CARs are 32 bits wide.
1 The settings on the Capability Registers page do not cause any features to be enabled
or disabled in the RapidIO IP core. Instead, they set the values of certain bit fields in
some CARs.
Device Registers
The Device Registers options identify the device, vendor, and revision level and set
values in the Device Identity (
Table 6–12 on page 6–11 ) and Device Information
( Table 6–13 on page 6–12 ) CARs.
Device ID
Device ID sets the DEVICE_ID field of the Device Identity register. This option
uniquely identifies the type of device from the vendor specified in the Vendor
Identity
field of the Device Identity register.
1 This DEVICE_ID field of the Device Identity register ( Table 6–12 ) should not be
confused with the DEVICE_ID field in the Base Device ID CSR ( Table 6–23 on
page 6–16 ).
Vendor ID
Vendor ID uniquely identifies the vendor and sets the VENDOR_ID field in the Device
Identity register. Set Vendor ID to the identifier value assigned by the RapidIO
Trade Association to your company.
Revision ID
Revision ID identifies the revision level of the device. This value in the Device
Information register ( Table 6–13 ) is assigned and managed by the vendor specified in
the VENDOR_ID field of the Device Identity register ( Table 6–12 ).
Assembly Registers
The Assembly Registers options identify the vendor who manufactured the assembly
or subsystem of the device. These registers include the Assembly Identity (
Table 6–14
on page 6–12 ) and the Assembly Information ( Table 6–15 ) CARs.
