Prob.2 : 10Min.
Total : 21 Mins..
When you submit the Hw., Please write down how
much time did you spend for each problem.
(No penalty for spending too little or too much
time. Just want to know how much you spent.)
How to submit: Hard copy during the class.
Prob0. Use the Synthesis
program, Draw the figure for the module.
module
slice_es(eo,a,b,ei);
input
a, b, ei;
output
eo;
wire
aneb, aeqb;
xor x1(aneb,a,b);
not n1(aeqb,aneb);
and a1(eo,aeqb,ei);
endmodule
Prob1. Use the Synthesis
program, Draw the figure for the module “compare”.( the figure maybe different(from
the one at the class) when you are using “bgx_shell -gui”)
module compare(gt, lt, a, b);
input a, b;
output gt, lt;
wire [2:0] a,
b;
reg gt, lt;
integer i;
always @( a or
b ) begin
gt = 0; lt =
0;
for(i=2;
i>=0; i=i-1)
if( !gt
&& !lt ) begin
if( a[i]
< b[i] ) lt = 1;
if(
a[i] > b[i] ) gt = 1;
end
end
endmodule // compare
Prob2. Use the Synthesis program,
Draw the figure for the module.( the figure maybe different(from the one at the
class) when you are using “bgx_shell -gui”)
module cond_form_1_example2(x,y,a,b,c);
input a,b,c;
output x,y;
wire [7:0] b,
c;
reg [8:0] x, y;
always @( a or
b or c ) begin
if( a )
begin
x = b +
c;
y = b -
c;
end else
begin
x = b -
c;
end
end
endmodule
