Tapeout checks
Tapeout combines clean physical verification with antenna, electrical, density, data-integrity, and release checks.
The final checklist proves that the exact released database—not an earlier intermediate—passed every required signoff.
An antenna violation may be fixed with a diode or metal-layer jump, followed by timing and DRC revalidation.

Understand every concept
Antenna verification
What it is: Antenna verification is a core concept within Tapeout checks. It describes the information, structure, or analysis engineers use at this stage of the Physical Verification flow.
Why it matters: Understanding it helps you interpret the stage correctly, avoid incorrect assumptions, and connect the result to the next implementation or signoff step.
Where it fits: This topic belongs to module 4, Tapeout checks, and its output supports the stages that follow.
Practical example: Engineer workflow: Run final DRC, LVS, antenna, and ERC decks. An antenna violation may be fixed with a diode or metal-layer jump, followed by timing and DRC revalidation.
ERC concepts
What it is: ERC concepts is a core concept within Tapeout checks. It describes the information, structure, or analysis engineers use at this stage of the Physical Verification flow.
Why it matters: Understanding it helps you interpret the stage correctly, avoid incorrect assumptions, and connect the result to the next implementation or signoff step.
Where it fits: This topic belongs to module 4, Tapeout checks, and its output supports the stages that follow.
Practical example: Engineer workflow: Verify fill, seal ring, labels, and hierarchy. An antenna violation may be fixed with a diode or metal-layer jump, followed by timing and DRC revalidation.
Final signoff checklist
What it is: Final signoff checklist is a core concept within Tapeout checks. It describes the information, structure, or analysis engineers use at this stage of the Physical Verification flow.
Why it matters: Understanding it helps you interpret the stage correctly, avoid incorrect assumptions, and connect the result to the next implementation or signoff step.
Where it fits: This topic belongs to module 4, Tapeout checks, and its output supports the stages that follow.
Practical example: Engineer workflow: Generate checksums and release manifests. An antenna violation may be fixed with a diode or metal-layer jump, followed by timing and DRC revalidation.
