PISO and SIPO

Hello,

I need to implement parallel-to-serial and serial-to-parallel blocks.

Is there any megawizard/function that does this in the Quartus?

and if not, how can I do it efficiently using verilog?

Thank you.

    Hello,

    you can use the LPM_SHIFTREG Megafunction or elementary HDL contsructs like this 

    always @(posedge clk)
  begin
    sr <= { sr, si}; // left shift, serial input
  end

    Regards,

    Frank
