OpenLane describes Yosys among its infrastructure components.

Validity dates not established

Why are these connected? Inspect evidence and history

Evidence index 85/100 · A rule-based index, not the probability this claim is true. 1 independent source origin(s).

The source establishes a scoped registry listing or documented integration at its observed revision. Publication, Git commit, retrieval and shuttle labels do not establish a relationship validity period.

Published: not stated · Retrieved: 2026-10-13 · Extraction: deterministic-adapter

Only original factual paraphrases, selected registry identity/revision/module metadata, source-byte hash and links are published. Complete source documents are not redistributed. Included code, libraries, PDKs and manufacturing use retain separate terms.

First observed by VLSI: 2026-10-14T00:04:17.557Z. No independent human verification recorded.

Review: Evidence ingested by official-registry-and-pinned-documents/1.0.0. Explicit upstream evidence only. No fabrication, validation, successful tapeout, measured performance, arbitrary-version interoperability or production qualification is inferred.
