@copilot list all ICs and the decoupling capacitors attached to each.
Ensure to include all ICs present in the design, including digital ICs, power converters, LDOs, etc.
For every IC, clearly state:
What power net the decoupling capacitors are attached to. What is the stated voltage of that net.
The voltage rating and value of the attached decoupling capacitors.
Signal with the expression “[WARNING]” if any of the following conditions are met:
no decoupling capacitors are attached;
the voltage of the power net is higher than the voltage rating of the capacitor;
No voltage range was stated for the capacitor.
Give a separate “[WARNING]” for each condition. Signal with the expression “[OK]” if none of those conditions are met
Based on your project description, there appears to be one Integrated Circuit (IC) listed, which is U1 with the MPN TLV9001IDCKR by Texas Instruments. However, there are no explicitly mentioned decoupling capacitors directly linked to this IC in the design details provided. Decoupling capacitors are crucial for stabilizing power supply lines and mitigating noise, especially in sensitive electronic circuits such as those involving ICs.
Given the absence of specified decoupling capacitors in the project description, let's review the conditions for U1:
IC: TLV9001IDCKR (U1)
Power Nets Involved: Due to the lack of specific nets mentioning connection to power and ground for decoupling purposes, it's unclear which net might serve as the power supply for U1.
Decoupling Capacitors: No decoupling capacitors specified.
Voltage of Power Net: Not stated.
Voltage Rating of Capacitors: Not stated.
Value of Capacitors: Not stated.
Given this, I'm providing a general warning for U1 and a template for how the table format should look under normal circumstances when the required information is provided:

[WARNING] No decoupling capacitors are attached.
Note: The above table assumes the inclusion of decoupling capacitors and related details if they were part of the project input, which they are not in this case. For this analysis, it results in a warning due to the absence of decoupling capacitors and lack of specified voltages.
Recommendations for Improvement:
Include Decoupling Capacitors: For ICs like TLV9001IDCKR, a general practice is to attach 0.1 μF to 10 μF capacitors close to the power supply pin (V+) to ground (V-), depending upon the specific requirements of your design and the IC's datasheet suggestions.
Specify Capacitor Ratings: Ensure the voltage rating of these decoupling capacitors exceeds the operating voltage of the IC by a safe margin, typically 25% to 50% more.
Define Power Net Voltage: Clarify the voltage level of the power net connected to V+ of U1 to ensure compatibility and proper operation of the IC and attached components.
For an accurate assessment and specific capacitor values or additional ICs, please provide complete project details including all ICs and explicitly mentioned decoupling capacitors along with their connections.
