Abstract:
With the rapid development of network technology, Ethernet technology has become the most widely used local area network technology with its excellent features. The Ethernet standard consists of multiple protocols to form a complete system. The 10Gbase-R protocol is one of the important basic protocol. This article is based on the PCS layer of the 10Gbase-R protocol, and deeply explores the key modules within the PCS layer: elastic buffers, 64B/66B codecs, scrambler/descrambler, bit-width converters, etc. It proposes a complete design architecture, and uses the verilog language to complete the RTL-level module design, then builds simulation verification platform and uses modelsim software to complete the functional verification, and completes related design.
