Aforloop is the most widely used loop in software, but it is primarily used toreplicatehardware logic in Verilog. The idea behind aforloop is to iterate a set of statements given within the loop as long as the given condition is true. This is very similar to thewhileloop, but is used...

从综合结果来看，Verilog中的for循环作用是：复制电路。其中i=0~3，故复制4份电路，和时钟没有关系。f...
1. 初始化数组或向量：在Verilog中，经常需要对数组或向量进行初始化。使用`for`循环可以方便地对数组中...
在Verilog中,for循环的执行方式取决于其被使用的上下文。在行为描述中,for循环通常是串行执行的;而在生成块中,for循环用于并行地生成硬件结构。因此,对于你的问题“verilog中for循环是串行执行还是并行执行”,答案是:它可以是串行执行的(在行为描述中),也可以是用于并行生成硬件结构的(在生成块中)。具体取决于for循环...
初始块外的for循环生成硬件(使用genvar),但verilog中初始块内的for循环工作方式与for循环软件类似,对吗? 当然,初始块仅用于模拟目的,因此用于循环的软件是有意义的。 这里就是一个例子。该示例中的测试台显示了讨论中for循环的使用情况,如下所示: module fsm_test; ...
A for loop in SystemVerilog repeats a given set of statements multiple times until the given expression is not satisfied. Like all other procedural blocks, the for loop requires multiple statements within it to be enclosed by begin and end keywords. Syn
Converting A Software-Style For Loop to VHDL/Verilog For loops are an area that new hardware developers struggle with. You have likely seen for loops dozens of times in C, so you think that they are the same in Verilog and VHDL. Let me be clear here: For loops donotbehave the same ...
Verilog 循环语句有 4 种类型,分别是 while,for,repeat,和 forever 循环。循环语句只能在 always 或 initial 块中使用,但可以包含延迟表达式。 while 循环 while 循环语法格式如下: while (condition) begin … end 1. 2. 3. while 循环中止条件为 condition 为假。
