输入的加数分别是两个4bit的向量 x[3:0] 和 y[3:0] ,输出为一个5bit的向量 sum[4:0] 。 module top_module( input [3:0] x, input [3:0] y, output [4:0] sum ); wire [2:0] w; FA A [3:0](.a(x[3:0]), .b(y[3:0]), .cin({w[2:0],1'b0}), .cout({sum[4]...
例如,out_any [2]应指示in [2]或in [1]是否为1。由于in [0]在右边没有邻居,答案很明显,因此我们不需要知道out_any [0 ]。 out_different:此输出向量的每一位都应指示相应的输入位与其左侧的邻居是否不同。例如,out_different [2]应指示in [2]与in [3]是否不同。对于此部分,将向量视为环绕,因此in...
Ok, let's try building several logic gates at the same time. Build a combinational circuit with two inputs, a and b. There are 7 outputs, each with a logic gate driving it: out_and: a and b out_or: a or b out_xor: a xor b ...

In a digital system, the logic circuits can be divided into two classes: combinational and sequential. A combinational circuit uses logic gates only; a sequential circuit uses flip-flops (ffs) and logic gates. The discussion of ffs is left to the next chapter. Most of the flip-flops are ...
Unlike sequential logic circuits, combinational circuits do not have memory; their outputs depend solely on the current state of the inputs. The invention of the combinational circuit, along with their ability to perform Boolean Algebra, has been an essential part of the digital revolution. This ...
Paired with this quiz and worksheet is a lesson called Combinational Circuits & Functions: Construction & Conversion. By studying this lesson, you can gain greater insight into the following: Composition of a circuit in electronics Three Boolean logic methods that can be used to design combinati...
Combinational logic circuits or gates, which perform Boolean operations on multiple input variables and determine the outputs as Boolean functions of the inputs, are the basic building blocks of all digital systems. We will examine simple circuit configurations such as two-input NAND and NOR gates ...
