vhdl语言集锦 VHDL是Very High Speed Integrated Circuit Hardware Descr iption Language的缩写,意思是超高速集成电路硬件描述语言。对于复杂的数字系统的设计,它有独特的作用。它的硬件描述能力强,能轻易的描述出硬件的结构和功能。这种语言的应用至少意味着两种重大的改变：电路的设计竟然可以通过文字描述的方式完成；电子电路可以当作文件一样来存储。随着现代技术的发展,这种语言的效益与作用日益明显,每年均能够以超过30 的速度快速成长。-VHDL language VHDL is an abbreviation for “Very High Speed Integrated Circuit Hardware Descr iption Language”. and is along with Verilog the most widely used hardware descr iption language. It is used to describe the behavior and structure of electronic systems, but is particularly suited as a language to describe the structure and behavior of digital electronic hardware designs. The application of it means two changes: electro circuit design can be done by the kind of file descr iption.　and electro circuit can be stored as a file.
