SmartScaling provides ML-based adaptive library characterization and scaling of libraries for multiple PVTs. It is a new methodology that is built on top of the PrimeTime? scaling engine, which uses existing characterized libraries as anchor PVT corners to then generate multiple additional PVTs instantly.

SmartScaling provides signoff accuracy for various library views ¨C NLDM, NLPM, CCST, CCSN, and LVF.

Two primary methods for SmartScaling are shown below.

Method 1

• SmartScaling-based PVTs generated via an existing characterized database, used as anchor PVTs.
• Here, based on the anchor corners provided by the customer, the SmartScaling engine will generate additional libraries at multiple PVT corners.

Synopsys offers a comprehensive library characterization solution.

PrimeLib is a unified library characterization and validation solution. The PrimeLib solution includes a comprehensive array of library characterization and quality assurance capabilities that are tuned to produce PrimeTime signoff-quality libraries with maximum throughput on available compute resources. Its innovative technologies utilize embedded gold reference SPICE engines to provide a characterization speed up of advanced Liberty? models used by PrimeTime static timing analysis (STA) to accurately account for effects seen in ultra-low-voltage FinFET processes that impact timing. This includes PrimeTime parametric on-chip variation (POCV), advanced waveform propagation (AWP), and electromigration (EM) analysis. PrimeLib is cloud-ready, and with its optimized scaling technology delivers an accelerated throughput on cloud or an on-premise cluster.
