Modelsim: Analog Waveform of grouped signals

I have a std_logic_vector in my design of say (31 downto 0). In fact it is an SPI command word, containing command, address and data.

I'd like to see the actual data of that std_logic_vector in an analog waveform in modelsims waveform viewer.

I just drag the signals (19 downto 4) into the waveform viewer and group them. Now, I was expecting that I can right click on the group and select 'Format->Analog(automatic)'. But I cannot select this, because it is greyed out.

Is there another way to generate an analog wave form from a sub std_logic_vector?

Regards, Maik

Solution

  • You have to use the option Combine Signals instead of Group then you can right-click and select Format->Analog(automatic)
