照惯例,还是先将官方说明贴出来,verilog 2001关于blocking and non-blocking assignment 表述如下: blocking assignment :A blocking procedural assignment statement shall be executed before the execution of the statements that follow it in a sequential block (see 9.8.1). A blocking procedural assignment state...
blocking與non-blocking是學習Verilog一個重要的關卡,若能掌握這四個原則,基本上就不會用錯。 Introduction 要徹底搞懂blocking和nonblocking老實說並不是很容易,需要一些篇幅(請參考(原創) 深入探討blocking與nonblocking (SOC) (Verilog))。在RTL級編碼中,若能掌握以下四個原則,基本上就不會誤用blocking與nonblocking: ...
In Verilog, a commonly known rule states that in always blocks , only blocking or only nonblocking assignments should be used, not a mix in one

If there are multiple assignment statements in the always block in verilog then they can be done in two different ways 1. Blocking using = 2. Non Blocking using <= We will first consider an example usage of Blocking and non blocking assignments in initial statements. The initial statements ...
官方文档原文传送门 https://www.verilogams.com/refman/modules/discrete-procedural/assignment.html?highlight=assign 和普通的C语言一样。ps.对于暂存，不要想存在哪里的问题，没必要了解。因为Verilog是硬件描述语言，这个是为了描述一些硬件中数据变化之类的行为。那么，左边的值什么时候发生改变，即赋值...

还有一种带repeat循环的Intra-Assignment Delays的过程赋值,例如: always @(IN) OUT <= repeat(8) @(posedge clk) IN; 可用于阻塞或非阻塞赋值。 为了能更好理解,代码加了一些$display,以显示语句执行的时间,据此统计次数 modulecomb_logic_assign16;bitin;bito1,o2,o3,o4,o5,o6;initialbeginin=0;o1=0;...
