How it works

Inventory selected built-in simulation-symbol inputs with no catalogued output on their net and catalogued push-pull outputs on simulation ground.

  • Uses the same bounded native-project validation, pin positions and net connectivity as the Ohmforge workspace.
  • Classifies built-in AND, OR, NAND, NOR, XOR, NOT and comparator simulation-symbol pins. Other component pins are unclassified, and may include sources.
  • Lists classified inputs with no classified push-pull output on their resolved net, including the number of unclassified component pins and whether the net is ground.
  • Separately lists classified push-pull outputs on simulation ground. Each list is limited to 100 terminals; total and omitted counts include all findings.
  • Roles describe the built-in simulation symbols and may not match physical components. A ground input can be intentional and the absence of a catalogued output does not prove that the input is floating.

This is a limited inventory, not proof that an input is floating or that a circuit is safe. Unclassified pins may include sources; a ground connection may be intentional. The review does not assess power, voltage, ratings or physical design.
