Revision History

Changes from Revision * (January 2026) to Revision A (September 2026)

  • Changed ring-back margin from ±60mV to RBMargin specified for SS and FF corners separately and clarified that CMD must be monotonic between VIL and VIH. Clarified when DAT can be non-monotonic between VIL and VIH in Simulation Strategy and Examples section.Go
  • Added 2 new figures - VIH/VIL: Non-monotonic DATn good example and bad example. Pass/Fail Checks Table - VIH/VIL (Ring-back) updated with RBMargin, monotonic CMD, and allowable conditions for non-monotonic DAT. Added clarifying language to figure titles.Go
