Device ID Registers for Function <n>
Table 4–9 lists the default values of the read-only Device ID registers. You can use the
parameter editor to change the values of these registers. At run time, you can change
the values of these registers using the reconfiguration block signals. For more
information, refer to “R**Hard IP Reconfiguration Interface ###if_hip_reconfig###” on
page 8–52.
PCI Express/PCI Capabilities for Func <n>
The following sections describe the PCI Express and PCI Capabilities for each
function.
Device
Table 4–10 describes the Device Capabilities register parameters.

Range
Default
Value
Description
Vendor ID
0x000
16 bits 0x00000000
Sets the read-only value of the
Vendor ID
register. This parameter can
not be set to 0xFFFF per the PCI Express Specification.
Device ID
0x000
16 bits 0x00000001 Sets the read-only value of the
Device ID
register.
Revision ID
0x008
8 bits 0x00000001 Sets the read-only value of the
Revision ID
register.
Class code
0x008
24 bits 0x00000000 Sets the read-only value of the
Class Code
register.
Subsystem
Vendor ID
0x02C
16 bits 0x00000000
Sets the read-only value of the
Subsystem Vendor ID
register. This
parameter cannot be set to 0xFFFF per the PCI Express Base
Specification 2.1. This register is available only for Endpoint designs
which require the use of the Type 0 PCI Configuration register.
Subsystem
Device ID
0x02C
16 bits 0x0000000
Sets the read-only value of the
Subsystem Device ID
register. This
register is only available for Endpoint designs, which require the use of
the Type 0 PCI Configuration Space.
Table 4–10. Function Level Reset
Parameter Value Description
Function level reset On/Off
Turn On this option to set the Function Level Reset Capability bit in the
Device
Capabilities
register. This parameter applies to Endpoints only.
