Abstract
With the development of electronic science and technology in our country, the lights is
increasingly integrated into the modern life of all kinds of landscape, as a kind of decoration lights
viewing tool life, not only satisfy the people visual enjoyment and entertainment, at the same time,
attention and fancy lantern designs, creativity, energy saving, intelligent and environmental
protection. But we cannot ignore the most important part in the design of colored lights, that is, the
control mode of colored lights, and the most obvious one is the extinguishing and lighting of
colored lights, as well as the changing back and forth of patterns. Therefore, it is very important
for color lamp to control pattern transformation. Therefore, this paper designs an 8-way color lamp
controller to meet this requirement.
This article will use the EDA technology to complete the design, each module program
written using VHDL hardware description language, and after analyzing the principle of
multi-channel lights controller, to control the lights all kinds of transformation of the pattern, so as
to achieve design goal. The main characteristic of EDA technology is that it adopts the top-down
design method to complete the overall structure design of the system. Programmers use hardware
description language, on EDA software platform and design documents, then automatically by the
Quartus II software platform to complete the logic compilation, simplify, segmentation, synthesis,
layout, wiring and simulation, until the target chip adaptive compilation, logical mapping and
programming downloads. Through the hardware emulation platform, to the waveform simulation
of various modules, observe the waveform to confirm the correctness of the circuit design, this
paper design the 8 channel lights controller controlled by three patterns: one is from both sides to
the middle, then from middle to both sides is bright; Second, fade in and out of the effect; Three is
to light from left to right, and then from right to left.
Controller to control the three circulation pattern, one is to realize the control of the lights, 2 it
