Field-Programmable Gate Arrays (FPGAs) can be found in an increasing number of application domains, such as the telecom industry, the automotive electronics sector, or automation technology as well as in the area of reconfigurable computing. In recent years, it can be observed that the open-source idea which is known from the software domain for a long time also became popular in the world of hardware and FPGA design. In the era of the Internet of Things, many of today’s electronic devices implement some kind of network interface with Ethernet being known as one of the most widely used network standards. Thus, there is consequently a high demand on available Ethernet implementations for FPGA platforms. The goal of this work is to survey available open-source Ethernet MAC IP cores, evaluate existing designs in terms of performance, resource utilization, code quality, or maturity, and to present and summarize the evaluation results herein. Furthermore, advantages of commercial solutions and related publication work are discussed. To the authors’ best knowledge, this is the first publication that evaluates and compares existing open-source Ethernet MAC IP cores on a large scale. This work should help designers to select an appropriate open-source Ethernet MAC for an FPGA design and shows possible pitfalls and things to pay attention when using an open-source IP core in general. Finally, the authors would like to show that the open-source community can be also very helpful in the world of hardware in terms of design reuse or time to market.
