- 连续赋值(continuous assignment):为网络赋值 -过程赋值(procedural assignment):为变量赋值 另外,还有两种不常见的赋值形式:赋值/去赋值(assign/deassign)和强制/释放(force/release),这两种赋值形式被称为过程性连续赋值,有时间后面博客再介绍这两种不常见赋值形式,我们还是先来看看最常用的连续赋值和过程赋值吧~ 赋...

首先，我们可以使用initial块来初始化一维数组的值。例如：verilog.module array_assignment;reg [7:0] data [0:3]; // 定义一个包含4个8位寄存器的一维数组。initial begin.data[0] = 8'b00000001;data[1] = 8'b00000010;data[2] = 8'b00000100;data[3] = 8'b00001000;end.endmodule.在这个例子中...
An initial value can be placed onto a variable at the time of its declaration as shown next. The assignment does not have a duration and holds the value until the next assignment to the same variable happens. Note that variable declaration assignments to an array are not allowed. ...
Array Assignment Array Example What are memories ? Register Vector Memory Example What is a Verilog array ? An array declaration of a net or variable can be either scalar or vector. Any number of dimensions can be created by specifying an address range after the identifier name and is called...
<module_name> <instance_name> <instance_array_range> (.<port_name_0> (variable0), .<port_name_1> (variable1), … .<port_name_N> (variableN)); 可以看出,相比于单独实例化语句,它主要多了一个<instance_array_range>参数,利用这个参数,我们就可以控制实例的数量。例如: ...
