mux2to1.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.

LIBRARY ieee ;
USE ieee.std_logic_1164.all ;

ENTITY mux2to1 IS
	PORT (	w0, w1, s	: IN 	STD_LOGIC ;
			f 			: OUT 	STD_LOGIC ) ;
END mux2to1 ;

ARCHITECTURE Behavior OF mux2to1 IS	
BEGIN
	PROCESS ( w0, w1, s )
	BEGIN
		IF s = '0' THEN
			f <= w0 ;
		ELSE
			f <= w1 ;
		END IF ;
	END PROCESS ;
END Behavior ;
