Mentor Graphics

Mentor Graphics was a leading electronic design automation (EDA) software vendor whose tools span integrated-circuit design and verification, PCB and electronic-systems design, and manufacturing analysis. Battery Ventures held a position in the company. In 2017 Mentor Graphics was acquired by Siemens and its portfolio now ships as Siemens EDA (part of Siemens Digital Industries Software), including Calibre for physical verification and DFM, the Questa functional verification platform, and the Xpedition / PADS PCB design suites. The mentor.com domain now redirects to the Siemens EDA site. Siemens EDA delivers desktop and cloud-hosted engineering software and managed services; it does not publish a public developer REST API, OpenAPI definition, or self-serve developer portal, so there is no public API surface to enrich for this provider.

Mentor Graphics is profiled on the APIs.io network. Tagged areas include Company, Electronic Design Automation, EDA, Semiconductors, and PCB Design.

Mentor Graphics’ developer surface includes support, pricing, engineering blog, getting-started guide, documentation, and 19 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0

8 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 0.0 — up to +25.0 composite points
Access Clarity scores 15.8 — up to +16.8 composite points
Developer Ergonomics scores 31.0 — up to +13.8 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/mentor-graphics/apis.yml: open an issue on github.com/api-evangelist/mentor-graphics to ask a question or point us at an artifact you publish.
