说明：  研究了传统误码仪的工作原理与结构，并运用VHDL语言在FPGA芯片上模拟实现了绝大部分的传统误码仪的功能，，如LCD显示出来驱动driver，串口通信驱动driver，误码测试，数据存储芯片驱动driver等功能.
(Study the working principle and structure of the traditional BERT, and the use of VHDL language to simulate most of the traditional BERT function on the FPGA chip, such as LCD displays out drive driver, the driver of the serial communication driver, error test drive driver functions, data storage chips.)
