Introduction

NanoSpice Giga is industry's Giga-scale SPICE simulator, its innovative parallel simulation engine is built using big data architecture that effectively handles billion-element designs. This capability makes NanoSpice Giga ideally suited for verification and signoff of memory, custom or semi-custom digital circuits, and fullchip designs.

NanoSpice Giga is designed for accuracy verification and signoff of advanced memory designs, an area where traditional FastSPICE has fundamental limitations. Pure SPICE engine of NanoSpice Giga offers significantly higher accuracy for power, leakage, timing/ noise characterizations and verification. NanoSpice Giga's superior parallelization technologies deliver faster simulation speed without sacrificing accuracy. With high accuracy and performance, NanoSpice Giga can serve as the golden signoff simulator for memory IP and full chip verification.
