Number of New Via Metals Created

Via metal types using the Array loss model are created to model your simplified vias in Sonnet. This setting controls how many via metal types are created in your translated project in order to model your simplified array. The fill factor is used to determine how many metal types are created. For more information on the fill factor and the Array loss model, please see Array Loss Model

There are three choices:

• Minimum: Creates the least number of via metal types but may be less accurate as a wider range of fill factors will be grouped together.
• Automatic: Creates the via metal types based on an algorithm that balances the trade off between accuracy and the number of via metal types produced. This is the default setting.
• Maximum: Creates the highest number of via metal types providing the most accurate answer since a via metal type is created for each unique fill factor.
