Ansys CML Compiler Helps CompoundTek Increase Automation for Building Compact Model Libraries

As an innovate leader in silicon photonics, CompoundTek set out to deliver 3-sigma statistical support to provide customers with best-in-class PDK models that are representative of CompoundTek’s proprietary manufacturing process.

Challenges

To deliver statistical support with minimal time-to-market, CompoundTek looked for innovative ways to improve its processes for the development and maintenance of PDKs.

Engineering Solution

• CompoundTek decided to go with CML Compiler embracing a solution for increased automation for building and maintaining compact model libraries (CMLs).
• With the addition of statistical support to CML Compiler, it was the perfect tool to help improve productivity. The statistical models enable CompoundTek customers’ designs to have a better fit of the simulation results with the actual performance, resulting in a more accurate prediction of the actual chip performance and yield.
• CML Compiler enabled integration of CMLs with 3rd party EDA tools, allowing customers to link their INTERCONNECT schematic to the layout and perform electro-optical co-simulation.
• The built-in capability of encrypting the CML was another feature that was important to CompoundTek.

Benefits

• Data requirements of CML Compiler makes it easier to identify what measurements are needed for statistical enablement of models.
• 从名义上的统计模型是东亚峰会ily accomplished by adding the required statistical data measured from CompoundTek’s actual silicon wafer.
• Built-in QA to verify statistical and nominal behavior of generated compact models.
• Ansys Lumerical’s technical support makes the process/troubleshooting easier.
