Protocol Verification - As a new generation of high-performance chip-to-chip packet transmission protocol, Interlaken is usually embedded in FPGA, ARM, DSP and other chips in the way of IP core. As a high bandwidth network communication protocol, relevant testing and verification work is the key to support users highly reliable applications.This paper analyzes the framing layer and protocol layer of Interlaken IP core embedded in FPGA, encapsulates the pre-defined data at the client end of the protocol layer, tests the working condition under the transmission rate of 100Gbps, and error injection in one segment of the four-segment user-side to simulate packet encapsulation errors. The study found that when sending packets, when any control word in any segment is lost, about 1/2 of the packets are received and about 1/4 are received correctly.
