所以Verilog要避免锁存器的两大原因是 （1）Latch对毛刺不敏感，设计不当，容易在电路中传播毛刺 （2...
构建一个在a和b之间进行选择的2对1 mux。如果sel_b1和sel_b2都为true,则选择b。否则,选择a。重复两次,一次使用assign语句,另一次使用过程if语句。 二、Verilog code module top_module( input a, input b, input sel_b1, input sel_b2, output wire out_assign, output reg out_always ); assign out_a...
The incomplete Verilog HDL code for the MUX2-1 is shown in the following:module Mux2_1 (In1, In2, sel, Out);parameter n=32;input [n-1:0] In1,In2;input sel;output [n-1:0] Out;___endmodulewhich of the following statements should be filled to the blank in the code to impleme...

The order of execution isn't always guaranteed within Verilog. This can best be illustrated by a classic example. Consider the code snippet below: initiala=0;initialb=a;initialbegin#1;$display("Value a=%d Value of b=%d",a,b);end ...
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...
Hello everyone. Mux verilog code below. They do the same, but option 2 got huge delays and cannot meet timing. Conclusion: they have different
