A、module D_FF ( input D,Clock,reset, output reg Q); always@(Posedge Clock or reset) if ( reset==1) Q <=0;
else Q <=D;
endmodule
B、module D_FF ( input D,Clock,reset, output reg Q); always@(posedge Clock or posedge reset) if ( reset==1) Q <=0;
else Q <=D;
endmodule
C、module D_FF ( input D,Clock,reset, output reg Q); always@(posedge Clock or negedge reset) if ( reset==1) Q <=0;
else Q <=D;
endmodule
D、module D_FF ( input D,Clock,reset, output reg Q); always@(posedge Clock or posedeg reset) if ( reset==0) Q <=0;
else Q <=D;
endmodule
E、module D_FF ( input D,Clock,reset, output reg Q); always@(posedge Clock or reset) if ( reset==1) Q <=0;
else Q <=D;
endmodule
F、module D_FF ( input D,Clock,reset, output reg Q); always@(posedge Clock) if ( reset==0) Q <=0;
else Q <=D;
endmodule
