A list of multicast addresses.
MCAST_ADDRESSLIST
Supported in configurations that contain the 1000BASE-X/SGMII PCS
0
Sets the
SGMII_ENA
bit in the
if_mode
register. See
If_Mode Register (Word Offset 0x14)
on page 6-26.
TB_SGMII_ENA
0
Sets the
USE_GMII_AN
bit in the
if_mode
register. See
If_Mode Register (Word Offset 0x14)
on page 6-26.
TB_SGMII_AUTO_CONF
Test Configuration Parameters
You can use these parameters to create custom test scenarios.
Table B-2: Test Configuration Parameters
Default
Description
Parameter
Supported in configurations that contain the 10/100/1000 Ethernet MAC
0
Enables local loopback on the Ethernet side (GMII/MII/RGMII). The
value must always be set to 0.
TB_RXFRAMES
5
Specifies the number of frames to be generated by the Avalon-ST
Ethernet frame generator.
TB_TXFRAMES
12
IPG on the receive path.
TB_RXIPG
0
0: A constant IPG,
TB_RXIPG
, is used by the GMII/RGMII/MII Ethernet
frame generator.
1: Enables variable IPG on the receive path.
TB_ENA_VAR_IPG
100
Specifies the payload length of the first frame generated by the frame
generators. The payload length of each subsequent frame is incremented
by the value of
TB_LENSTEP
.
TB_LENSTART
1
Specifies the payload length increment.
TB_LENSTEP
1500
Specifies the maximum payload length generated by the frame
generators. If the payload length exceeds this value, it wraps around to
TB_LENSTART
. This parameter can be used to test frame length error
by setting it to a value larger than the value of
TB_MACLENMAX
.
