Piplining, what is the best way?

Dear Rbugalho,

thank you for your kind answer! It seems that my newbie question was not very precisely posted, what I need is

You may also need synchronizer chains for the outputs.

I mean, I have several blocks, let's say like

B1=A1*A2;
B2=A1*A3;
B3=A2*A3;

and I want to put them in pipeline. What is the correct way to do it? Is it correct to do it like following:

always @(posedge Clk1)
begin
  X1=C1*C2;
  X2=C1*C3;
  X3=C2*C3;
  C1=B1*B2;
  C2=B1*B3;
  C3=B2*B3;
  B1=A1*A2;
  B2=A1*A3;
  B3=A2*A3;
end

Sorry, for my newbie questions. I really want to understand the situation because I need to implement very complicated pipe-line algorithm.

Sincerely,

Ilghiz
