This immediate scheduling is crucial for executing tasks or events promptly without waiting for simulation time to progress. 46. Write a Verilog code for 5:1 MUX module mux_5to1(input [4:0] data, input [2:0] sel, output reg out); always @(*) case(sel) 3'b000: out = data[0];...
4'd1:q = e; 4'd2:q = a; 4'd3:q = d; default: q = 4'hf; endcase end endmodule 6【题目】: 根据下面的时序图实现这个组合逻辑电路。 【个人思路】 : 可以看出这是一个根据输入a的取值来进行输出的组合电路,可以用case语句来根据a的取值来进行输出。 module top_module ( input [2:0] a...

【题目】在Verilog HDL中,下列标识符是否正确(1)system1 (2)2reg (3)FourBit_Adder (4)exec$ (5)_2to1mux 相关知识点: 试题来源: 解析 【解析】解:(1)、(3)、(4)和(5)正确;(2)错误,因为标识符通常由英文字母、数字、8符或者下划线组成,并且规定标识符必须以英文字母或下划线开始,不能以数字或8...
Learn about designing a multiplexer in verilog with example code, specifically a 4x1 or 4 to 1 mux
4. Verification: Reading Simulations 4.1 Finding bugs in code 4.1.1 Mux(Bugs mux2) This 8-bit wide 2-to-1 multiplexer doesn't work. Fix the bug(s). module top_module ( input sel, input [7:0] a, input [7:0] b, output out );assign out= (~sel & a) | (sel & b); ...

Parentheses may be omitted if the code formatting conveys the same information, for example when describing a priority mux. 👍 assign foo = condition_a ? a : condition_b ? b : not_a_nor_b; Comments C++ style comments (// foo) are preferred. C style comments (/* bar */) can also...
You could download file mux_without_default.v here The example above shows how to specify multiple case items as a single case item. The Verilog case statement does an identity comparison (like the === operator); one can use the case statement to check for logic x and z values as show...
case(case_expr) condition1 : true_statement1 ; condition2 : true_statement2 ; …… default : default_statement ; endcase 小tips: default 语句是可选的,且在一个 case 语句中只能有一个 default 语句。 case 语句支持嵌套使用。 代码示例: module mux4to1( input clk, input [1:0] sel , input...
