module adder_t2 (co, sum, a, b, ci);
output co;
output [3:0] sum;
input [3:0] a, b;
input ci;
reg co;
reg [3:0] sum;
always @(a or b or ci)
#12 {co, sum} <= a + b + ci;
endmodule
I am sorry that I didn't make my question clear.Do these blocking and nonblocking assignment reflect the actual circuit?
Can anyone code an example?
