Model Quality Assurance (MQA)



Model Quality Assurance (MQA) is a collection of comprehensive SPICE model validation procedures, interfaces and utilities that provide the ability to thoroughly check SPICE model quality and automate QA and reporting procedures for both silicon and III-V technologies. Given today’s nanoscale process technologies and increasing model complexities, validating SPICE models is a significant challenge and can be very time consuming. However, SPICE modeling engineers and model users still want the models to be thoroughly checked and the model characteristics to be easily obtained. MQA satisfies this critical industry requirement by rigorously checking the model quality, plotting model charac­teristics, and customizing the output targets with its comprehensive checking rules while employing easy-to-use interfaces and utilities.

Key features

Integrates a comprehensive set of rules to ensure SPICE model quality while overlaying measurements and simulation results

Support for commercial simulators. Equipped with internal SPICE engine for fast simulation

Rules and checking functions are flexible and fully customizable

Customize user defined plots and/or tables with Python script

Measurement QA, model comparison, corner model QA and Monte Carlo analysis

Powerful plotting functions and utilities

Open interface enables flexible support of models, simulators and checking routines

Automatic QA report generation and customization

Complete parallelism support on different levels: simulator level, rule level and project level

Native support of IC-CAP mdm data and MySQL/SQLite database


Support for Python script

Generate customized plots and/ or tables by post-processing MQA results

No additional simulation is needed

Enable target calculation and data processing

Easily plug in existing user scripts


Powerful model reporting

MQA is equipped with a powerful report module:

Easily output all desired tables and plots to a report format of the user’s choice (i.e. Word, Excel, PowerPoint, HTML, PDF or OpenOffice)

Easily output all existing MQA plots to a report

Report content is rule driven and user customizable


Open interface

MQA provides an open interface for advanced users to utilize their own math functions and data process functions.

Implement more math functions with little programming

Customize/add RMS functions of your preference

MQA’s Java interface has its own engine that enables users to edit, compile and debug their own programs


Powerful plotting

Check scale, zoom in/out and digitalize the plots and apply math functions

All plots can be saved to a graphic file

The curves can also be displayed in a table

Plot Smith Chart, polar chart and noise figure

Easily view the previously generated results

Generate 3D plots
