Reg data type as Sequential element

module reg_seq_example( clk, reset, d, q);

input clk, reset, d;

output q;

reg q;

wire clk, reset, d;

always @ (posedge clk or posedge reset)

if (reset) begin

q <= 1'b0;

end else begin

q <= d;

end

endmodule

There is a difference in the process of assigning to reg when modeling combinational logic: in this logic we use blocking assignments when modeling sequential logic we use nonblocking ones.
