FPGA Development Board - strange shift operation behavior

--- Quote Start ---

Why not just add the statement:

led <= circle_count == 4'd0 ? BASE_LED_SEQUENCE : led << 1;

into the main loop, so it looks like this:

always @(posedge clk or negedge reset)
    begin
    if (!reset) 
        begin
        count <= 28'd0;
        circle_count <= 4'd0;
        led <= 12'b0;
        end
    else
        begin
        if (count == 1)
            begin    
            count <= 1'b0;
            circle_count <= circle_count == 4'd12 ? 4'd0 : circle_count + 4'd1;
            led <= circle_count == 4'd0 ? BASE_LED_SEQUENCE : led << 1;
            end
        else
            count <= count + 28'd1;
        end
    end

which I think is a lot easier to follow.

Thank you,

It's pretty well working.

But could you explain me why I can't get previous value for `led` in other always blocks?
