Giga-scale SPICE Simulator – NanoSpice Giga™


NanoSpice Giga™ is the industry's first and only GigaSpice, designed for accurate verification and signoff of advanced memory designs, an area where FastSPICE is meeting fundamental limitations. With its innovative parallel simulation engine built on a big data architecture, NanoSpice Giga can handle billion-elements designs, targeting the verification and signoff of various memory circuits, custom or semi-custom digital and full-chip designs. Compared to FastSPICE, NanoSpice Giga uses a pure SPICE engine to offer much higher accuracy for power, leakage, timing and noise characterizations and verifications, Its superior parallelization technologies delivers faster simulation speed without scarifying accuracy. NanoSpice Giga directly replaces FastSPICE and serves as a golden signoff simulator for memory IP and full chip verifications.

Key Benefits

Superior accuracy: true SPICE accuracy with DC convergence, for accurate power/leakage/timing/noise
Giga-scale capacity: handles real full chip verification and signoff (>109 elements)
High performance: faster than FastSPICE and scalable to 32+ threads. Specially optimized for FinFET/FD-SOI models
No FastSPICE options: no tuning, removes guesswork from FastSPICE
Foundry validated accuracy: 16/14/10nm FinFET and 28nm FD-SOI ready


Embedded memory IP verification
Full chip memory IC verification (DRAM,SRAM,Flash)
Memory characterization
Custom or semi-custom digital: clock tree, critical path analysis
