摘　　要：LOCic是针对欧洲核子中心LHC的ATLAS中液氩量能器前端电子单元的两通道、耐辐射、低功耗高速串行传输器。该系统工作在强微粒子辐射环境下,其高速数据采集和传输会出现突发的多位连续数据位错和数据流位滑。针对上述情况,基于Stratix II GX FPGA设计了模拟以上差错现象的注入器,用于后端数据解码和恢复系统的设计与测试。测试和实验结果表明,该差错注入器有效可行。LOCic is a two-channel radiation-tolerant low power high-speed serializer in ATLAS liquid argon calorimeter＇s fron- tend electronic read out unit for CERN LHC. The burst of multi-bits errors and bit slip errors appear in the LOCic as the high- speed data are collected and transferred under the extremely high levels of radiation environment. Based on above issues, the de- sign of error injector based on Stratix II GX FPGA was proposed to simulate the errors and was applied to the design and test of the decoder and restore system of back-end system. The results of experiments and tests show the error injector is valid.
