（1）能够测试10HZ~10MHZ的方波信号； （2）电路输入的基准时钟为1HZ，要求测量值以8421BCD码形式输出； （3）系统有复位键； （4）采用分层次分模块的方法，用Verilog HDL进行设计，并对各个模块写出测试代码； （5）具体参照说明文档（包含源代码，仿真图，测试波形，详细的设计说明）(A square wave signal capable of testing 10HZ~10MHZ; (2) the reference clock input by the circuit is 1HZ, and the measured value is output in the form of 8421BCD code; (3) the system has a reset key; (4) adopt the method of layering sub sub module and design with Verilog HDL; (5) write test simulation program.)

8路视频光端机 接收侧 VHDL源码，使用了千兆以太网SERDES芯片，基于TBI接口的PCM视频传输。-8-Channel Video Optical Receiver side of VHDL source code, using the Gigabit Ethernet SERDES chip, based on the TBI interface PCM video transmission.

在QuartusII运用ＡＨＤＬ语言，首先设计出PN发生器来产生一个11位的数据流在整个周期内有效数据有 =2047位；再设计状态机用来检测串行数据流中的序列。运用两个个计数器分别对PN码计数以及序列出现的次数计数。改变ＰＮ码结构可以作为通用数列检测器-QuartusII use in AHDL language, the first PN generator designed to generate a data stream 11 throughout the cycle has an effective data = 2047 re-designing the state machine used to detect the serial data stream in sequence. The use of two counters were counting on the PN code, as well as counting the number of sequences occur. Changes in the structure of PN code series can be used as general-purpose detector
