Star-Hspice Features
Star-Hspice is compatible with most SPICE variations, and has the following additional features:
Superior convergence
Accurate modeling, including many foundry models
Hierarchical node naming and reference
Circuit optimization for models and cells, with incremental or simultaneous multiparameter optimizations in AC, DC, and transient simulations
Interpreted Monte Carlo and worst-case design support
Input, output, and behavioral algebraics for parameterizable cells
Cell characterization tools for calibrating library models for higher-level logic simulators
Geometric lossy coupled transmission lines for PCB, multi-chip, package, and IC technologies
Discrete component, pin, package, and vendor IC libraries
AvanWaves interactive waveform graphing and analysis from multiple simulations

Simulation at the integrated circuit level and at the system level requires careful planning of the organization and interaction between transistor models and subcircuits. Methods that worked for small circuits might have too many limitations when applied to higher-level simulations.
You can organize simulation circuits and models to run using the following Star-Hspice features:
Explicit include files – .INC statement
Implicit include files – .OPTION SEARCH = `lib_directory’
Algebraics and parameters for devices and models – .PARAM statement
Parameter library files – .LIB statement
Automatic model selector – LMIN, LMAX, WMIN, WMAX model parameters
Parameter sweep – SWEEP analysis statement
Statistical analysis – SWEEP MONTE analysis statement
Multiple alternative – .ALTER statement
Automatic measurements – .MEASURE statement
