# AI EDA Evaluation Pack

This rubric is designed for reviewing AI-generated electronics design assets. A generated asset should not be marked acceptable until a human reviewer checks circuit intent, component values, operating limits, and simulation or hand-calculation evidence.

| Failure type | Broken asset | Corrected asset | Required evaluator diagnosis | Pass criteria |
| --- | --- | --- | --- | --- |
| Missing flyback diode | MOSFET low-side motor driver with motor inductance and no clamp path | Diode from MOSFET drain/motor low side to VBAT, cathode at VBAT | Identify inductive kickback risk and explain why the drain voltage can rise when the switch turns off | Correctly adds clamp path and verifies drain behavior in transient simulation |
| Wrong RC cutoff | Low-pass filter claims 1.6 kHz cutoff but uses 1k and 10 nF | Uses 10k and 10 nF, or recalculates cutoff for the actual values | Compute `fc = 1 / (2*pi*R*C)` and compare against the design target | Correct value math and frequency-response evidence |
| ADC overvoltage | Divider sends a 5 V sensor signal directly into a 3.3 V ADC range, or uses a ratio that still exceeds the ADC rail after tolerance | 22k / 33k divider scales 5 V to about 3.0 V before tolerance review | Check worst-case input voltage, resistor ratio, ADC absolute max, and loading | Output stays within ADC input range across expected tolerance |
| Floating op-amp input | Amplifier schematic leaves a non-inverting or bias reference input floating | Adds DC bias or defined input return path | Explain that an op-amp input needs a valid common-mode and bias path | Corrected schematic has defined operating point and expected gain |

## Scoring Guidance

- **Reject:** The asset has an unsafe or nonfunctional circuit flaw, lacks values, or cannot be simulated/inspected.
- **Needs revision:** The asset is directionally correct but misses a calculation, tolerance check, source note, or validation artifact.
- **Acceptable sample:** The asset has a clear circuit boundary, plausible values, a human validation note, and either SPICE output or a hand-check matching the stated behavior.
- **Strong sample:** The asset includes source files, corrected artifact, expected behavior, observed behavior, and explicit limitations.

## Required Labeling

If an example is AI-generated, label it as AI-generated at the point of display. Do not present an AI-generated design as corrected, safe, manufacturable, or production-ready unless a human validation note is included beside it.
