Faulty DDS behavior

Hello,

 

I tried to overclock the DDS IP core by adding the clock enable bit, but TVALID from the output data bus does not reflect this bit activity (at least in simulated behavior, but because of that I have not pushed it further).

 

I know the idea behind the DDS is to produce one sample per clock cycle, but in this situation TVALID should only be asserted when clk enable is '1', otherwise you will end up oversampling the output data.

Re: Faulty DDS behavior

The DDS does not provide the oversampling feature.
