Is should I trust AI for block-diagrams/architecture for PCB?
Hi everybody, I've been working at an engineering internship for around 2 weeks now, and they've asked me to create a 13x13 channel continuity test fixture. It's supposed to measure if a test is <2ohms, and my supervisor said it should be within a 10% accuracy. I've gone with a robust and extremely accurate 4-wire kelvin sensing design with relay switches.
I have some experience designing PCBs (schematic, layout, assembly) but I never had to design the block diagram/concept of the circuit.
When I was designing this board, I've never made the block diagram for boards before. I came up with a few ways to create this text fixture, and I even asked my design team lead about it, but I ended up just sticking with the design that Copilot convinced me was the best.
That being said, I'm really doubting my choice now. To me, what it said made sense, and I tried to verify it myself, but I don't really understand alot of things it said. (For example, it was so insistent I should use reed relays over load switches/muxes, but I didn't understand why for my specific design.)
Alot of the time the AI would be super insistent on something but I would convince it otherwise with my own reasoning. It's been completely wrong a few times (such as when it convinced me I had the wrong footprint for a schematic, when it was perfectly fine).
The problem is that I'm pretty inexperienced, and since the AI is wrong alot too, it's like the blind leading the blind. I want try to decide what's the best way to design something myself, but it always convinces there's some current leakage/on resistance/EMI issue I'm never aware of.
To make it clear, I'm NOT talking about if AI can make an entire PCB or even touch schematic/layout. I'm relatively confident in my ability to design schematic/layout, and even though I'm a dumb first year I can definetly do it better than AI.
My question, TLDR: Is AI good for block-diagrams/architecture for PCB?
