Displaying Analog signals in Modelsim

Hi all,

Can anyone know how to view analog signals in Modelsim?

NCO IP's can generate accurately analog signals in FPGA?

 

Thanks all;

@sivakumarreddy50,

Can anyone know how to view analog signals in Modelsim?

You need not to do anything special. Just add the signal to waveform window.

An analog signal is a signal which changes value with increasing time (as opposed to non-clock digital signals). So if you can create such a signal, you can simulate your RTL and view the signal.

Whether the signal is o/p of some IP core or your RTL does not matter.

Hi @sivakumarreddy50 

As suggested by @dpaul24  add the analog signal to the  wave window, In addition to this right click to this signal  go to  format -> analog automatic., you will be able to observe the analog signal which fits to the simulation window similar to below

Re: Displaying Analog signals in Modelsim

Just a quick note, there is no real analog signal in the FPGA, apart form the input / output of the ADC / DAC
its just how you want to view a signal,
