Software facilitates nanometer design timing analysis.

TimeCraft(TM) features On-Chip-Variation (OCV) for improving static timing analysis of 90 and 65 nm designs. OCV engine provides level- and location-based OCV analysis, addressing effects of on-chip statistical process variation. By eliminating excessive guard banding, it improves timing accuracy and reduces effort to close timing closure. OCV uses variable derating factors based on logic level
