The “Standard for IP Abstraction for Clock and Reset Domain Crossing Integration” enables interoperable, tool-independent CDC/RDC collateral exchange and signoff from IP to SoC design flows.

CDC/RDC verification is essential to avoid metastability, glitches, and data reconvergence errors when signals traverse asynchronous clock or reset boundaries. Historically, analysis results and ‘intent’ generated by different tools could not be reused across different EDA tools, forcing re-runs and manual translation during integration. The standard defines a vendor‑neutral approach to capture CDC/RDC intent to enable efficient CDC/RDC signoff for IP providers and SoC integrators, across the EDA vendor ecosystem.

The Standard for IP Abstraction for Clock and Reset Domain Crossing Integration was developed by the CDC Working Group.
