Overview

Product Description

The CORE Generator™ Virtex™ 5 Embedded Tri-mode Ethernet Media Access Controller (MAC) Wrapper automates the generation of HDL wrapper files for the embedded Tri-mode Ethernet MAC in Virtex 5 devices. Preconfigured HDL wrappers as well as testbenches and implement and simulation scripts are generated automatically based on user defined options.

Key Features and Benefits

  • Provides user configurable Virtex 5 Tri-mode Ethernet MAC (TEMAC) physical interface
  • Simplifies interconnection between the Ethernet MAC and the PHY
  • Allows selection of one or both of the two Ethernet MACs (EMAC0 or EMAC1) from the Ethernet MAC primitive
  • Individual DCR base address for EMAC0/EMAC1
  • Sets EMAC0/EMAC1 attributes based on user options
  • Supports MII, GMII, RGMII v1.3, RGMII v2.0, SGMII, and 1000BASE-X PCS/PMA interfaces
  • Clock Enable inputs on the Transmit and Receive clients available when the Ethernet MAC is configured in GMII/MII or RGMII modes (halves the BUFG requirements)
  • "Byte PHY" clocking scheme for Tri-Mode GMII/MII (halves the BUFG requirements)
  • Instantiates BUFs, DCMs, GTPs, and logic required for MII, GMII, RGMII, SGMII, and 1000BASE-X PCS/PMA interfaces
  • Includes testbench for wrappers using the EMAC and GTP Smartmodels
  • Generates VHDL or Verilog® wrappers
  • 16-bit client interface supports 2Gb/s data rates
  • Implementation scripts and UCF file
  • Simulation scripts for Mentor® Modelsim® and Cadence™ IUS (functional and timing simulation)
