Hi, i have simulated this NCO IP using small ROM options.Then i run the tcl script to simulate the waveform in modelsim.Now was it possible to display this sin and cos waveform on the oscilloscope? Using the audio out? The board i am using is altera DE2 board and do please tell me the step on displaying this signal on oscilloscope or vga.
Connect a DAC to it's output. You can use Video DAC for that I suppose, but I am not sure about audio DAC, since there is audio codec, not simple dac on DE2.
Ok so i need to use the vga to pc lcd monitor but i could not find the info in nco manual to send the signal to the monitor. I wish it was easy like assigning the 7-bit segment like i use to do it in verilog.
I am not sure, check the datasheet of the DAC. Should be enough, since vga driver needs to generate vertical and horizontal timing impulses, which are not needed in this case.
