hi,

if i use your vhdl file i would write this in the top level entity:

nco_inst : nco13 port map(

clk => clk_in,

reset_n => reset_n

...

);

and one more thing i noticed in the first vhdl file you sent :

look at reset_n and clk_en, they got the same signal "clk_en".

I doubt that reset_n has the same polarity than clk_en.
