Model Quality Assurance
Model Quality Assurance
Challenge:
SPICE model validation is a critical step in the design flow and difficult to conduct automatically.
Model validation encompasses more than overlaying the measurement results to model's simulation results.Foundry and design teams require improved communication.
Model validation procedures and documentation must be automatic and customizable.
Solution:
MQA (Model Quality Assurance) provides the complete solution and framework to fabless design companies, IDMs, and foundries for SPICE model library validation, comparison, and documentation. MQA provides semiconductor technology alliances and industry SPICE model QA standard and allows an open communication environment. MQA performs Model QA, comparison, and documentation automatically and ensures design success using advance process technologies.

Listen to what our customers say about MQA
"We use it as a QA tool to evaluate models from our foundries and use the results as one of the criteria for accepting and releasing new models to our design team. MQA tool provides us a convenient way to check changes between new model and previous versions, and evaluate all critical model parameters for BSIM based device models as well as device DC and certain RF performances. The user interfaces are very user friendly. As a first time user, I was able to run it without spending too much time. Accelicon MQA support team did a great job in supporting my requests, and fixing bugs and problems in a timely manner. In general, we had a good experience with the tool and support." --Modeling Engineer
"MQA has tremendously improved the model release cycle time while enhancing model quality. Whether using it on foundry supplied or internally generated models, MQA has helped our customers find and solve modeling issues in a timely manner. It's flexibility with different simulators and model formats plus the ability to do customized tests makes it a must for any design house." - Foundry Interface Engineering Manager.
