And various shapes of LED lights, with the continuous development of technology, EDA design get continuously development and application of LED lamp represents pattern is varied, the most simple several water light LED lights, lights and running water can be controlled by the ring counter or twisting the ring counter. This article is based on the circular counter and twisting the ring counter as the design object. According to the counter relevant laws , the counter is to design the operation circuit .this design adopts hierarchical method and verilog hardware description language to realize. This article is mainly related to counter circulation and since the start and final of the test scheme and simulationThis design can realize some simple control counter, and modelsim simulation Keywords: ring counter and twisting the ring counter design ; Verilog; modelsim. 目 录 TOC \o 1-2 \h \z \u HYPERLINK \l _Toc388991423 1.引言 1 HYPERLINK \l _Toc388991424 2.设计任务和要求 1 HYPERLINK \l _Toc388991425 2.1设计任务 2 HYPERLINK \l _Toc388991426 2.2设计要求 3 HYPERLINK \l _Toc388991427 3.设计原理 3 HYPERLINK \l _T
