Altera Arria V Avalon-MM - Manual (Page 30)

Parameter Value Description
Enable hard IP status bus On/Off When you turn this option on, your top-level variant
includes the signals necessary to connect to the
Transceiver Reconfiguration Controller IP Core, your
variant, including:
• Link status signals
• ECC error signals
• TX and RX parity error signals
• Completion header and data signals, indicating the
total number of Completion TLPs currently stored
in the RX buffer
Altera recommends that you include the Transceiver
Reconfiguration Controller IP Core in your design to
improve signal quality.
Enable hard IP status
extension bus
On/Off When you turn this option on, your top-level variant
includes signals that are useful for debugging,
including link training and status, error, and the
Transaction Layer Configuration Space signals. The
top-level variant also includes signals showing the
start and end of packets, error, ready, and BAR signals
for the native Avalon-ST interface that connects to the
Transaction Layer. The following signals are included
in the top-level variant:
• Link status signals
• ECC error signals
• Transaction Layer Configuration Space signals
• Avalon-ST packet, error, ready, and BAR signals
Avalon to PCIe Address Translation Settings
Number of address pages 1, 2, 4, 8, 16, 32,
64, 128, 256, 512
Specifies the number of pages required to translate
Avalon-MM addresses to PCI Express addresses
before a request packet is sent to the Transaction
Layer. Each of the 512 possible entries corresponds to
a base address of the PCI Express memory segment of
a specific size. This parameter is only necessary when
you select 32-bit addressing.
Size of address pages 4 KBytes–4
GBytes
Specifies the size of each memory segment. Each
memory segment must be the same size. Refer to
Avalon-MM-to-PCI Express Address Translation
Algorithm for 32-Bit Bridge for more information
about address translation. This parameter is only
necessary when you select 32-bit addressing.
