PrimeTime ® Advanced OCV Technology

Product Marketing Manager, Synopsys Introduction An accepted trend in the semiconductor industry, where process geometry is continuously shrinking, is the growing impact of variation in static timing analysis (STA). Similar to Signal Integrity (SI), which was introduced as a first order effect in 130-nm and then became more sophisticated over geometry nodes, on-chip-variation (OCV) started at 130-nm and its effects are increasing with shrinking geometry nodes. A preliminary solution to account for OCV was to apply a flat global margin across the entire chip. However, the growing impact of variation in modern designs requires an improved OCV handling capability that takes advantage of improved device-level variation techniques.
