在VHDL(VHSIC Hardware Description Language)中创建异步边缘检测器涉及数字信号处理的基本概念,特别是关于如何检测信号中的边缘变化。异步边缘检测器不依赖于全局时钟信号,而是基于输入信号本身的变化来检测边缘。 基础概念 异步边缘检测器通常使用两个连续的状态来检测边缘:一个用于检测上升沿(从低到高的变化),另一个用...
By the way, that video is created with VHDL and an FPGA. You will be able to do that soon enough! Next we will discuss another fundamental VHDL keyword: process.

In many cases, identifying these problems is a very time consuming process. Even worse, some of these issues can lead to the dreaded situation of a design working in simulation but not after synthesis. Since these types of problems can take an indefinite amount of time to debug, I strongly...
