说明：  LED流水广告灯 工程说明 在本案例中，使用常用的verilog语言完成该程序，设计并控制8个灯的花式或循环点亮；即上电后，实现左移和右移交替的流水灯。 案例补充说明 在FPGA电路设计中，尽管流水灯的设计属于比较简单的入门级应用，但是其运用到的方法，是FPGA设计中最核心和最常用部分之一，是FPGA设计必须牢固掌握的基础知识。从这一步开始，形成良好的设计习惯，写出整洁简洁的代码，对于FPGA设计师来说至关重要。
(LED flow advertising lights Engineering description In this case, use the commonly used Verilog language to complete the program, design and control 8 lights fancy or cycle light; that is, after power, to achieve the "left shift" and "right shift" alternating water lamp. Case Supplement In FPGA design, although water lamp design is an entry-level application is relatively simple, but the method is one of the most important and most commonly used parts of FPGA design, FPGA design is the foundation of knowledge must have a firm grasp of the. From this step, it is important for FPGA designers to form good design habits and write neat, concise code.)
