SIMetrix 9.1: The High-Performance SPICE Simulator for Demanding Circuit Design
SIMetrix 9.1 is a powerful, professional-grade mixed-mode circuit simulator built on the robust foundation of SPICE (Simulation Program with Integrated Circuit Emphasis). It is designed for electronic engineers and designers who require high accuracy, fast simulation speeds, and an intuitive workflow for analyzing complex analog, digital, and mixed-signal circuits. Combining a sophisticated simulation engine with a modern graphical user interface, SIMetrix 9.1 provides a comprehensive environment for everything from simple DC operating point checks to advanced transient, AC, and noise analysis, making it an indispensable tool for IC design, power electronics, and board-level verification.
Core Philosophy: Accuracy Meets Usability
SIMetrix bridges the gap between the raw power of traditional SPICE and the need for a streamlined, user-friendly design flow. It retains the depth and precision required for professional work—including support for advanced device models and convergence controls—while offering features like schematic-driven simulation, interactive probing, and automatic model library integration that dramatically improve productivity.
