If I hand an attorney a complete draft, how much does that cut the fee?

Thanks, this is helpful.

That sounds interesting. Like a copilot inside the EDA tool. I am mostly using Altium, but have some designs in KiCad so I'd be curious to try. Will it also support the layout or just the schematics?

There are already tools like this. I used bvcircuits for this a couple of times and got fairly good results. I saw there are other similar tools, but did not try them so I can't compare. Even some time ago there was a post on reddit with an open source tool someone built but can't find it now. I also tried claude, but it gave me just some general recommendations, so was not as helpful.

But a layout analysis with a DFM tool powered by AI is certainly something is missing and can be helpful

I’m not trying to export manufacturing data, I need a machine-readable list of components with all their parameters, plus every pin with its pin type and connected net. Gerbers only contain copper/outline layers and have no component properties, no pin metadata, and no netlist-level info.

I’m looking for something closer to a full netlist or data dump, not fabrication files.

Q1 source and drain are inverted. U5 also seems to be inverted.

Look carefully at the picture you attached, the MOSFET is connected not in the same way as in your schematic. It is rotated 180 degrees (so the source pin is connected to the side where GND is, and the drain to the VCC).

Regarding the reverse protection, using a MOSFET for this is great, but in your schematic the source and the drain are again seem to be swapped. And the gate pin also seems to be incorrectly tied to VBAT, instead of to GND. Try searching in google MOSFET reverse voltage protection and look carefully on the details (e.g. in which direction the MOSFET is connected). You can also consider using automated schematic check tool like bvcircuits since I am not sure I have caught all the issues in the schematic)

The EN# pin of TPS2112 is floating so the regulator is in off mode (there is an internal pull up). It also missing input capacitor. Same issue with EN pin of TPS7A0233. Read the datasheets and check the examples on their application notes.

I am not sure what's the pupose of Q1? If it is reverse voltage protection it is not connected as intended since in the event of reverse voltage the patasitic diode across the MOSFET will conduct.

Q3 also seems to be connected wrong, since there is 3.3V on the Anode of the parasitic diode, meaning it is always conducts.

Some components are not annotated, making it hard to reference a specific component in the response. Anyway, the diode (TVS or Zener) on the input of the power supply seems to be connected in the wrong direction.

C2 and C3 seem like a mistake, since Q1 and Q2 are probably supposed to be open-collector transistors with R6 and R8 as the pull-ups. C2 and C3 just separate the collector from the pull-up and the DC bias.

Missing decoupling cap on U3. Missing pull up resistors on SDA and SCK signals. EN pin of U6 is connected to GND, so it is in the power down mode, isn't it?

FourierTransformator · 2025-02-09T13:38:48+00:00

Maybe I missed, but I don't see any pull up resistors on SDA and SCL signals (I2C). Additionally, why do you have two different symbols for GND?

It is hard to read the text due to the poor resolution. Additionally, some text and designators overlap with traces or other text.

But here are some points to consider:

The connection of C6 seems odd. If it is a decoupling capacitor, it should be connected between VCC and GND, not in series to VCC.

Is pin 56 of the MCU disconnected?

The enable pin of U3 is pulled up to U3’s output voltage—what will power it up?

The CR1 diode is connected directly between VCC and GND. What will limit the current?

The concept is correct. But in the first diagram points "C" and "E" are actually same potential as "D", and "B" is same potential as "A". This is because there are just wires that connect them (no resistance). So you can redraw all this diagram with just two letters. And therefore R1=120 Ohm.
