Standard Cell Statistical Characterization with VarMan

With each new semiconductor process node, process variation, both global and local, play an increasingly significant role in determining standard cell library performance. When combined with supply voltage and temperature variation, traditional approaches to finding 3-sigma process corners or performing 6-sigma verification becomes impractical due to the large number of simulations that are required. In this webinar we will review how VarMan, from Silvaco, addresses this problem. The VarMan suite of tools includes Fast Monte Carlo, Variability eXplorer, high-sigma Yield Estimation, high-sigma Performance Limit, and library VarMan. These unique tools greatly reduce the number of simulations required for standard cell library characterization and quality assurance, while maintaining high accuracy, which makes design and characterization in the presence of variation feasible.

What attendees will learn:

  • Key challenges of Standard Cell Statistical Characterization
    • Large number of process corners
    • Difficulty in finding worst case conditions
    • Large number of simulations required for high-sigma verification
    • Situation complicated by local mismatch
  • Overview of statistics related to standard cell statistical characterization
  • Application of VarMan to Standard Cell Library Characterization
    • Fast Monte Carlo
    • Variability eXplorer
    • High-sigma performance limit and yield analysis
    • Library VarMan
