这是基于verilog语言写的

module DPLL(fin,fout,fout2,kclock,reset,k,N,H);
input fin,kclock,reset;
input[3:0] k;
input[7:0] N;
input[7:0] H;
output fout,fout2;
reg fout,fout2;
wire se,carry,borrow,idclock,idout;

DPLL_xor      DPLL1(fin,fout,se);
DPLL_2KCOUNT  DPLL2(se,reset,k,kclock,carry,borrow);
DPLL_H        DPLL3(idclock,kclock,H,reset);
DPLL_3count   DPLL4(idclock,carry,borrow,idout,reset);
DPLL_4count   DPLL5(fout2,idout,N,reset);
DPLL_two      DPLL6(fout2,fout,reset);
