【正文】 ll start to undertake a greatly part of numerical system design mission at the Verilog language. The VHDL language is a kind of deluxe language which useds for an electric circuit expects to appear after the 8039。t see part), since involve internal function and calculate way of entity to plete part to 1 designed entity to define exterior interface after, once it internal development pletion after, other designs can directly adjust to use this kind of will design entity to be divided into a little bit basic VHDL system that is a VHDL system inside the concept of outside part design design of a little bit basic and other hardware describe the language pare and the VHDL has a following characteristics: The function is strong and the design be VHDL has the function strong language structure, can describe a plicated logic control with the simple and direct and explicit source has a multilayer design description function, in multiple layers thin turn, finally directly born electric circuit class VHDL supports synchronous electric circuit, difference39。t pare VHDL still supports various design method, since support from the bottom upward design, support again from the design of crest declivity。s turn a design again. Support extensively and be easy to a the VHDL has already bee IEEE standard the norm of hardware description language, most EDA tools almost support VHDL currently, this is VHDL of further expansion with extensively applied lay the design process of the hardware electric circuit, the main design document is the source code which writes with the VHDL, the VHDL easily reads with the structure turn, so be easy to a modification design. The strong system hardware describes VHDL has a multilayer design description function, since can describe system class electric circuit, can describe door class electric circuit description since can adopt a behavior description, deposit a machine to deliver description or structure description, can also adopt the hybrid description of threes , VHDL support is inertial to delay and deliver to delay, can also accurately build up hardware electric circuit support prepare definite of with from definition of data type, bring hardware description a bigger freedom degree, make design the personnel can expediently establish the system model of high time. The independence is at the design of spare part, have nothing to do with the 39。s to carry on exchanges and share, decrease hardware electric circuit design. (1)pared with other hardware description languages, the VHDL have stronger behavior description ability, e to a decision him to bee a system design realm the best hardware a description language strong behavior description ability is to avert from concrete spare part structure and describe and design important assurance of largescale electronics system from the logic behavior. (2)the VHDL be abundant of imitate true language sentence and database function, make in any big system of the design can inspect a function possibility of design the system in early days, can carry on imitating true emulation to the design at any time. (3)the ability and procedure structure of the behavior description with lexical VHDL e to a decision the deposition that he ha
