组合逻辑电路:如果把组合逻辑电路的内部看做一个如下图所示的黑盒子一样,那么不去理会内部的逻辑到底是什么样子的,那么只有源(source)数据的输入的目的(destination)数据的输出吗,在数字系统中,source和destination一般是寄存器。组合逻辑电路的输出的数值变化在当输入驱动变化时候,会立即产生相应的变化! 组合逻辑基本框架...
The present paper describes some algorithms for generating complete test sets for bridging faults in combinational logic circuits. It is shown how the concept of Boolean difference, which is well understood in the case of stuck-type fault situations, can be employed to generate the complete test ...

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]...
Combinational Logic Design Abstract Chapter 2 addresses combinational logic, in which the outputs depend only on the current inputs. The logic gates introduced in Chapter 1 are examples of combinational logic. This chapter shows how to design circuits involving multiple gates in order to implement a...
Even though CAD tools are used to create combinational logic circuits in practice, it is important that a digital designer should learn how to generate a logic circuit from a specification. Understanding this process allows the designer to better use the CAD tools, and, if need be, to design...
Combinational circuits are types of digital circuits that output a binary value, based on a set of input signals. These circuits are generally constructed using logic gates such as AND, OR, NOT, NAND, and NOR gates. They do not have any memory elements or feedback loops, meaning the output...
