Each post explains one idea for a chip-package engineer or a technical investor, and links to the published record behind it. Every number in the posts is read from a published file when the pages are built. Every file this site publishes is listed with its size and checksum.
Why a flat model of a via misses its ends
A flat, two-dimensional model of a vertical connection ignores its ends, and a three-dimensional solver is how a team can check what that costs.
What an independent-solver check shows, and what it does not
Grading a predictor against solvers its authors did not write is stronger than grading it against their own, but it still has limits.
Re-checking a small mask edit without starting over
A published method can show that an edited mask tile is still valid by reusing the margin its old certificate carried, but only for one edit at a time.
The printing check that stays inside its computed range
A computed range around a simulated print contained the detailed simulation's value in every one of a large battery of checks, within the limits the record states.
