@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
  • Express the result in a markdown-formatted table

@copilot Check that none of the unconnected pins require pull-up or pull-down resistors to ensure proper function.
