VIRTEX-4
Description
The LogiCORE™ Virtex-4™ 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™. 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 integration of the Ethernet MAC by providing HDL examples based on user-selectable configurations.
Key Features
- Allows selection of one or both Ethernet MACs (EMAC0/EMAC1) from the Embedded Ethernet MAC primitive Design File Formats Constraints File Example Designs
- Connects the EMAC0/EMAC1 tie-off pins based on user options
- 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™ Multi-Gigabit Transceivers (MGTs), and logic as required for the selected physical interfaces
- Provides a simple FIFO-loopback example design, which is connected to the MAC client interfaces
- Provides a simple demonstration test bench based on the selected configuration
- Includes an example of a low-level driver for DCR accesses
- Generates VHDL or Verilog
- The precise number depends on user configuration; see "Device Utilization" on page 7.
- The Virtex-4 Embedded Tri-Mode Ethernet MAC User Guide is available under the Related Information area of the product page.
