HiGig Ethernet MAC IP Core

Compliant to the Broadcom HiGig and HiGig2 Protocol Definitions


Newsletter Subscription

The HiGig™ MAC transmits and receives data between a host processor and a HiGig™ / Ethernet network that enables networking customers to add features like quality of service (QoS), port trunking, mirroring across devices, and link aggregation at higher layers of the OSI network model. The HiGig™ MAC ensures that the Media Access rules specified in the 802.3ae IEEE standard and HiGig™ Protocol definitions are met while transmitting a frame of data over Ethernet. On the receive side, it extracts the different components of a frame and transfers them to higher applications through a FIFO interface.

Allows the Configuration of the IP and Generation of a Netlist and Simulation File - The HiGig™ / Ethernet MAC IP core is a user-configurable IP core, which allows the configuration of the IP and generation of a netlist and simulation file for use in designs. Please note that generating a bitstream may be prevented or the bitstream may have time logic present unless a license for the IP is purchased. The HiGig™ MAC IP core from Lattice supports the LatticeECP3 and LatticeSC/M FPGA families.

1. Performance and utilization data are generated using an LFE3-35EA-7FN672CES device with Lattice Diamond 1.1 software. Performance may vary when using a different software version or targeting a different device density or speed grade within the LatticeECP3 family.
2. The HiGig Ethernet MAC IP core itself does not use any external pins. However, in an application the core is used together IODDR and I/O Buffers integrated in the LatticeECP3 series FPGA. Thus the application implementing the HiGig MAC specification will utilize I/O pins.

Evaluate/Purchase: Unlike other LatticeCORE IP, the HiGig™ MAC IP core cannot be directly downloaded from the Lattice IPexpress Server. Please request this IP from Lattice at lic_admn@latticesemi.com and include your name, company, and complete contact information. A setup file for installation of the IP into IPexpress will be sent to you. Execute the setup file and then use IPexpress to evaluate and configure the IP core.

Purchase: To find out how to purchase the IP Core, please contact your local Lattice Sales Office.
