Complete SPICE Modeling Services

Silvaco provides SPICE modeling services for the semiconductor industry. We offer an experienced staff of engineers and state-of-the-art laboratory. Our services are affordable, and designed to provide the accuracy and rapid turn around time required by our customers.

Silvaco’s modeling services are ideally suited to either compliment in-house SPICE modeling capabilities when time is critical, or to provide complete SPICE modeling services for occasional needs. We support CMOS, Bipolar, Diode, JFET, GaAs SOI, TFT and HBT technologies, as well as technologies requiring the use of macro modeling.

Modeling service is performed by using UTMOST III and UTMOST IV modeling software: Automated data acquisition, SPICE model parameter extraction, Model validation and Model generation. First released in 1984, UTMOST III today is the established industry standard for SPICE parameter extraction. UTMOST IV is a new state-of-the-art optimization and SPICE modeling software.
