Document digital logic - FPGA - Logic Diagram

[TNTY100]

I'll just quote @arquer in #3991 so it's in the category Ideas rather than Q&A :

Hi, I am an FPGA designer and I am very interested in using mermaid to document digital logic designs. Looking through the different diagram/graphs/charts/... that mermaid offers I have not seen anything quiet like what I am looking for. Ideally I would like mermaid to allow me to draw something like this:

Maybe basic gates too:

My idea would be to have some basic/low-level building blocks like flip-flops, LUTs, Multiplexers, Demultiplexers. Is mermaid capable of something like this currently?
