hello,
am working on a project waveform generation using fpga , i did sine wave with 1k freq(verilog, vhdl) but now i required sine wave with freq. upto 400khz plz gimmi some tips.
I fear, that's far from a clear problem description.but hardware is not working
[/COLOR]I just checked it that core is working perfectly but led is not glowing. Can you please tell me where the problem can be?
It's good to add a heartbeat signal to every design to verify that the bit file loaded like FvM said. Just divide your clock to 2 Hz and have it clock a T flipflop and send that signal out to the LEDs. If you don't see your heartbeat, you have bigger problems than the DDS IP core
If you have access to Chipscope, I would add an ILA core and see what's going on inside the FPGA.
