Two-dimensional (2D) arrays in SystemVerilog are a data type that allows the storage of values in a grid-like structure, similar to a matrix or a table. 2D arrays are declared using the syntax `type array_name [rows][columns];`, where `type` is the data type of the elements in the array, `array_name` is the name of the array, and `rows` and `columns` are the dimensions of the array.
For example, the following code declares a 2D array named `my_array` with 3 rows and 4 columns, where each element is a 32-bit integer:
```
int my_array[3][4];
```
You can access individual elements of a 2D array using two indices, one for the row and one for the column. For example, to access the element in the second row and third column of `my_array`, you would use the syntax `my_array[1][2]`.
