Cadence Rate Limits
Cadence Design Systems publishes no rate limits for any of its callable surfaces. The Orion Programming Guide documents client-side timeout and retry behaviour and a server-side request timeout, but never a request-per-window limit; no RateLimit-*/X-RateLimit-* headers or 429 semantics are documented, and none were observable on the one anonymous endpoint that answers (mmds.eyesopen.com returns 403 before any limiter is reached).
Cadence Rate Limits is the machine-readable rate-limit profile for Cadence Design Systems on the APIs.io network, conforming to the API Commons Rate Limits specification.
Tagged areas include Electronic Design Automation, EDA, Rate Limiting, Quotas, and Throttling.
