func1.vhd

一本很好的关于学习VHDL的书,Fundamentals of Digital Logic with VHDL Design,我的导师在教我VHDL时使用的教材.上传的是书内包含的所有的代码.

ENTITY func1 IS 
	PORT ( 	x1, x2, x3 	: IN 	BIT ; 
			f 			: OUT	BIT ) ; 
END func1 ; 

ARCHITECTURE LogicFunc OF func1 IS 
BEGIN   
	f <= (NOT x1 AND NOT x2 AND x3) OR 
		(x1 AND NOT x2 AND NOT x3) OR 
		(x1 AND NOT x2 AND x3) OR
		(x1 AND x2 AND NOT x3) ; 
END LogicFunc ;
