Combinational for-loop: Vector reversal 2 一、问题描述 Given a 100-bit input vector [99:0], reverse its bit ordering. 给定一个100位的输入矢量[99:0],反转其位顺序。 二、Verlog code module top_module( input [99:0] in, output [99:0] out ); integer i; //【方法一:always@(*)-for】...
26. Is it required to list every input in the Sensitivity Disc for a Pure Combinational Circuit? If so, why then? In pure combinational circuits, it’s essential to list all input signals in the sensitivity list because the output directly depends on the inputs. Any change in inputs must...

Combinational circuits modeling in Verilog can be done using assign and always blocks. Writing simple combinational circuits in Verilog using assign statements is very straightforward, like in the example below assign y = (a&b) | (c^d); ...
Logic synthesis tools cannot accept all Verilog code. The designer needs to ensure that the hardware description language code is a cycle-to-cycle register transfer level description. Loop structures such as while must provide termination conditions in the form of signal edges (such as @(posedge ...
