Introduction
The LogiCORE鈩?Virtex-4鈩?Embedded Tri-Mode
Ethernet Media Access Controller (MAC) Wrapper
automates the generation of HDL wrapper files for the
Tri-Mode Ethernet MAC in Virtex-4 FX devices using
the Xilinx CORE Generator鈩?
VHDL and Verilog instantiation templates are available
in the Libraries Guide for the Virtex-4 Ethernet MAC
primitive; however, due to the complexity and the large
number of ports, the CORE Generator simplifies inte-
gration of the Ethernet MAC by providing HDL exam-
ples based on user-selectable configurations.

Features
鈥?Allows selection of one or both Ethernet MACs
(EMAC0/EMAC1) from the Embedded Ethernet
MAC primitive
鈥?Connects the EMAC0/EMAC1 tie-off pins based on
user options
鈥?Provides user-configurable Ethernet MAC physical
interfaces, including
- Supports MII, GMII, RGMII v1.3, RGMII v2.0,
SGMII, and 1000BASE-X PCS/PMA interfaces
- Instantiates clock buffers, DCMs, RocketIO鈩?/div>
Multi-Gigabit Transceivers (MGTs), and logic as
required for the selected physical interfaces
鈥?Provides a simple FIFO-loopback example design,
which is connected to the MAC client interfaces
鈥?Provides a simple demonstration test bench based
on the selected configuration
鈥?Includes an example of a low-level driver for DCR
accesses
鈥?Generates VHDL or Verilog
