在gates-to-RTL仿真时没有setup/hold time问题。 Verilog层次结构 •Verilog通过在模块中实例化其他模块的方法支持层次化的硬件描述,高层模块对底层模块创建实例,通过input,output和inout端口进行联系。这些端口既可以是scalar也可以是vector。 •通过模块实例,一个模块可以把其他模块包含到自己的模块内,可以对其他子...
There are several statements in Verilog that have no analog in real hardware, e.g. $display. Consequently, much of the language can not be used to describe hardware. The examples presented here are the classic subset of the language that has a direct mapping to real gates. ...
Synthesis is the stage in the design flow which is concerned with translating your Verilog code into gates - and that's putting it very simply! First of all, the Verilog must be written in a particular way for the synthesis tool that you are using. Of course, a synthesis tool doesn't ...

44.Gates 题目: 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 ...
Problem 38: Reduction: Even wider gates(Gates100) 牛刀小试 构建具有100个输入的组合电路。 电路一共有3个输出: 解答与分析 上一个问题已经说过归约运算符了,这道题应该很简单吧~~~ 代码语言:javascript 代码运行次数:0 运行 AI代码解释 moduletop_module(input[99:0]in,output out_and,output out_or,ou...
It is highly detailed, defining the hardware structure explicitly and using primitive gates or modules to represent the actual physical components of the circuit. 29. Which software is used for Verilog? Tools like Xilinx Vivado, Altera Quartus, Synopsys Design Compiler, and Mentor Graphics ModelSim ...
原题:https://hdlbits.01xz.net/wiki/Gatesv 解析:out_both和out_any可以各从in中拿出正好差了一个下标位置的3位来,进行位运算即可得结果。out_different是手动做了一个in循环右移一位的临时vector,然后和原vector按位异或 moduletop_module (input[3:0] in,output[2:0] out_both,output[3:1] out_any...
Verilog has built in primitives like gates, transmission gates, and switches to model gate level simulation. To see how the gate level simulation is done we will write the Verilog code that that we used for comparator circuit using primitive gates. module...
Verilog is such a simple language; you could easily write code which is easy to understand and easy to map to gates. Code which uses if, case statements is simple and cause little headaches with synthesis tools. But if you like fancy coding and like to have some trouble, ok don't be ...
