How to check signal waveform.

cwjcwjcwj,

You can use the Vector Waveform to do that checking, but it is normally used to check (functional or timing simulation) sequential behaviours, not just combinational. However, to check the output signal, you must to add to your Vector Waveform file the inputs and output of your architecture.

To add those inputs/outputs (or signals) do: Edit -> Insert -> Insert Node or Bus

after, just choose the pins as Rysc has already said.

You must to set the configuration of your input and after save the file. Make the compilation and then verify the output pins.

My best,
