need help - Verilog/VHDL program, prototype boards, EDA

[d531]

Help!!!

I got a text paper today, there are 3 questions below that I don't know how to answer them. Can somebody help out? Huge thxs.

1. Design a program with Verilog or VHDL which can detect a series of bits (such as 1010) in a long serial stream.

2. Supposing that you are going to design an electric system. Please describe the design flow from schematic design with EDA software you are familiar with to complete a prototype board debug.

3. After you get the prototype boards from the manufacturing factory, what will you check on the board before and after you power it up? Refer to the simplified schematic drawing below.

Help!!!

hi , shift register complete detect a series of bits

module series_det ( clk ,
rst ,
sin ,
dout
);
input clk,rst;
input sin;
output dout;

reg [ 3 : 0 ] buf_reg;

alwasy @ ( posedge clk or posedge rst )
if ( rst )
buf_reg <= 0;
else
buf_reg <= { buf_reg [ 2 : 0 ] , 1'b0 };

assign dout = buf_reg == 4'b1010 ;
endmodule
