True. This is what I intended to do as the last resort. I even started
to learn more on decoders, but then found a discouraging thread:
https://sourceforge.net/p/sigrok/mailman/sigrok-devel/thread/d3d98bb1-2cc9-5fa1-36ed-b4957dc366d3%40linux.com/#msg36700866
/Q. I could not write a decoder because I found no way to output a logic
trace: the four registrable OUTPUT_* seem to serve another purpose.//[...]
//A. Nope, there's currently no OUTPUT_LOGIC (and also no OUTPUT_ANALOG)
yet, but both are features we want to eventually have indeed.//
/
Is this true? All decoders I saw displayed their output on the screen...
If I jump into writing my own decoder (for basic Logic operations on
channels), will I be able to place the decoder output on the screen?
If yes, then I will follow this path.

Hi!
You can always create a Python decoder for your specific case.

Wow! I've been occasionally using Sigrok/PulseView for last couple of
years. Flexibility of this software always amazed me. But this time I
was certain that I'm making some unknown fundamental mistake. not being
able to find the right way of ORing or ANDing the signals... Thanks for
letting me know.
I guess such info should be explicitly mentioned in the manual. I have
no idea who takes care of the doc, but I can volunteer to update if
desired.

Hello Darek,
You can't find it because it's currently not implemented :)
I recently implemented math channels for analog signals, math channels
for
logic signals will follow soon.

Dear All,
Apologies, my question is not really intended for dev community, but I
can't find the answer elsewhere despite my efforts last days.
I'm troubleshooting one of automation boards with several outputs. I
need to do a simple math on its output states (AND, OR mainly) to get
better visibility of the board state. Pretty typical, basic
functionality found in legacy logic analyzers. But ... I cannot find
anything like this in PulseView. What I am doing wrong? How can I
display a logical AND or OR of two or more signals?
Best regards,
-DarS
