Core10100 v4.0
Parameter
CSRWIDTH
Values
8, 16, 32
Default
Value
32
Description
Sets the width of the data bus used to access the registers within the
core.
Defines the maximum number of frames that can reside in the
TCDEPTH
1 to 4
1
transmit FIFO at one time. The maximum number of frames that
reside in the TX FIFO at one time is 2 TCDEPTH .
Defines the maximum number of frames that can reside in the
RCDEPTH
TFIFODEPTH
1 to 4
7 to 12
2
9
receive FIFO at one time. The maximum number of frames that
reside in the RX FIFO at one time is 2 RCDEPTH -1.
Sets the size of the internal FIFO used to buffer transmit data. The
size is 2 TFIFODEPTH × AHB_DWIDTH / 8 bytes.
The transmit FIFO size must be greater than TCDEPTH times the
maximum permitted frame size.
RFIFODEPTH
7 to 12
10
Sets the size of the internal FIFO used to buffer receive data. The
size is 2 RFIFODEPTH × AHB_DWIDTH / 8 bytes.
The receive FIFO size must be greater than RCDEPTH times the
maximum permitted frame size.
RMII
0, 1
0
When set to 1, the core supports RMII interface. When set to 0, the
core supports MII interface.

Parameter
Values
Default Value
Description
Must be set to match the supported FPGA family.
11 – Axcelerator
12 – RTAX-S
14 – ProASIC PLUS
FAMILY
0 to 99
17
15 – ProASIC3
16 – ProASIC3E
17 – Fusion
20 – IGLOO
21 – IGLOOe
This controls the core’s support of half-duplex operation.
0 – Half- and full-duplex operation supported
FULLDUPLEX
0 to 1
0
1 – Full-duplex only
When set to '1', the collision and backoff logic required to
support half-duplex operation is omitted, reducing the size of
the core.
