Advanced Modeling Tool


MeQLab is a high-performance SPICE modeling platform for both baseband and RF device modeling, from characterization, data validation, model extraction to model library generation and QA. MeQLab also supports cell circuit validation and design-oriented model characterization. It integrates data analysis and visualization, fast SPICE simulation,  optimization algorithms, an easy programming environment and an embedded SPICE modeling knowhow. MeQLab-RF, a new module focused on RF modeling and QA up to 110GHz, further extends MeQLab's capability, which features full capability of handling RF raw-data, de-embedding and characterization, smooth conversion from baseband model to RF model, DC characteristics verification, RF model extraction, RF model library generation and QA.

Key Benefits
