Elements of Statistical SPICE Models

Lu N., Watts J., Springer S.K., IBM, US

We discuss several elements of statistical SPICE models and present our solutions. We present (i) a solution of automatically detecting Monte Carlo vs. skewed simulations, (ii) a method of modeling an arbitrarily given asymmetric or [...]

Device Correlation: Modeling using Uncorrelated Parameters, Characterization Using Ratios and Differences

McAndrew C.C., Drennan P.G., Freescale Semiconductor, US

Partial correlations between parameters of different types of devices, such as effective channel lengthfor PMOS and NMOS devices, are often modeled and simulated statistically via correlation coefficients.However this is cumbersome and inefficient from a modeling [...]

On the Correlations Between Model Process Parameters in Statistical Modeling

Slezak J., Litschmann A., Banas S., Mlcousek R., Kejhar M., ON Semiconductor, CZ

Statistical modeling in the design of todays high performance integrated circuits (ICs) is a necessity to produce competitive products with short development time. The use of backward propagation of variance (BPV) has proven its worth [...]

Unified Statistical Modeling for Circuit Simulation

McAndrew C., Drennan P.G., Motorola, US

Accurate statistical simulation and modeling are important for IC design. Different types of statistical simulation require different types of statistical models. In this paper a unified approach to statistical modeling and characterization is presented. Based [...]
