Design A: Use Quartus Prime to simulate D flip$-$flops.

$$ Design A$-1$: Design an edge$$triggered D flip$-$flop in a $.$bdf file. The D flip$-$flop

symbol is under $>$ primitive $>$ storage $>$ dff$,$ or after you launch the Symbol

dialogue window, simply search dff then choose the component. You need to

create the Clk and D signals as inputs and make Q as output.
