Verilog `assign` statement is used to assign a value to a wire or a reg type variable in a continuous assignment. It is used to create a connection between two or more signals in a design. The syntax for `assign` statement is as follows:
```
assign <output_signal> = <input_signal>;
```
Here, `<output_signal>` is the signal or variable that is being assigned a value, and `<input_signal>` is the signal or expression whose value is being assigned to `<output_signal>`.
For example, let's say we want to connect an input signal `a` to an output signal `b`. We can use the `assign` statement as follows:
```
module my_module(a,b);
input a;
output b;
assign b = a;
endmodule
```
In this example, the value of input signal `a` is continuously assigned to output signal `b`. If the value of `a` changes, the value of `b` will also change accordingly.
