Rule deck (runset)
Beginner
The factory’s rule book, written so a computer can check a chip drawing against it.
Novice
A file supplied by the factory that encodes its manufacturing rules (minimum widths, gaps and so on) as a program a checking tool can run over a layout.
Expert
A foundry-qualified program for one physical verification tool: layer definitions, derived layers built with Boolean operations, and hundreds to thousands of geometric checks, plus device and connectivity definitions for LVS. Decks are versioned, and the checklist records which version was run.
Explained in Signoff (Design Flow).
