这张表就叫做"真值表"(truth table),其中的sum表示"和位",carry表示"进位"。如果A和B都是0,和就是0,因此"和位"和"进位"都是0;如果A和B有一个为1,另一个为0,和就是1,不需要进位;如果A和B都是1,和就是10,因此"和位"为0,"进位"为1。 二、逻辑门(Logic Gate) 布尔运算(Boolean operation)的规...
Create a circuit that has two 2-bit inputs A[1:0] and B[1:0], and produces an output z. The value of z should be 1 if A = B, otherwise z should be 0. module top_module ( input [1:0] A, input [1:0] B, output z ); assign z = A==B?1:0; endmodule 3.1.1.10 Sim...
