Signing off some tiles near a chip-mask edit, in simulation: the lab’s exact wording
The lab’s own sentences and figures for this result, word for word, in its working terms, with its limits in plain words where the lab’s text cannot be reprinted. The plain account is on the result’s page; it says the same things in plain words.
The lab’s plain-English sentence
When a single, isolated small edit is made to a chip-printing stencil (mask) design, the lab's method proves in its own simulator that neighbouring design tiles affected by the edit are still valid without recomputing them
- by checking that a proven limit on the edit's effect fits inside the safety margin each tile already had
- on the lab's own test edits it saved recomputing only about 1% of tiles
Point-by-point checks against a full recomputation, in the lab’s words
with 0 violations over 9,175,040 pointwise comparisons
The limit to read first, in the lab’s words
over a FOUR-EDIT CHAIN, 9 of 64 tile serves fell below from-scratch, worst by 4.3267 nm
Over a chain of edits, declared honestly
On the same chain the honest declaration served 0 of 64 below from-scratch
Claim
A tile whose inputs did move is proved still valid when a certified bound on the edit's influence fits inside the margin its stored certificate was already carrying, with 0 violations over 9,175,040 pointwise comparisons.
Over the same chain, with a deliberately mis-declared setting
with update(declared_halo=0), a falsification knob whose every result is stamped NOT a certificate, over a FOUR-EDIT CHAIN, 9 of 64 tile serves fell below from-scratch, worst by 4.3267 nm
