int my_array[3:0][4:0]; 3. 如何初始化Verilog中的二维数组 在Verilog中,二维数组的初始化可以通过在initial块中逐个赋值的方式来实现。此外,也可以使用generate语句结合循环来批量初始化数组元素。 逐个赋值的示例: verilog module TwoDimensionalArrayExample; reg [7:0] two_dim_array [2:0][2:0]; in...
数组可以作为参数传递给子程序,当数组作为值传递给子程序时,会将这个数组复制一份传递给子程序。task trial (int a[3:1][3:1]); //’a’ is a two-dimensional array //(2-D unpacked) 上面是一个SystemVerilog task声明的示例,该task会将一个2维unpacked数组作为参数值传递。int...

There is a one-dimensional array of cells (on or off). At each time step, the next state of each cell is the XOR of the cell's two current neighbours. A more verbose way of expressing this rule is the following table, where a cell's next state is a function of itself and its ...
reg arrayb [ 7:0][255:0]; // two-dimensional array of one bit registers Assigning and Copying Verilog Arrays Verilog arrays can only be referenced one element at a time. Therefore, an array has to be copied a single element at a time. Array initialization has to happen a single elemen...
It is uncertain how effectively ports support multi-dimensional arrays, but SystemVerilog 2001 does provide support for multi-dimensional array types. To hold the data as a 4x4 Array: reg [7:0] data [0:3][0:3]; If the matrix is not taken as an input but rather shifted in and stored...
array2[7:0] Personally I prefer the array2 form for consistency, since I also write vector indices (square brackets before the array name) in [most_significant:least_significant] form. However, this is only a preference not a requirement. A multi-dimensional array can be declared by having...
