Model Library Development for Photonic PDKs

Photonic Model Development Kit

Proven, automated, cross-simulator photonic compact model library (CML) generation. CML Compiler automates the creation, maintenance and QA testing of INTERCONNECT and Verilog-A photonic compact model libraries (CMLs) from a single data source of characterization measurements and 3D simulation results.

Increased Productivity

Focus on component design and measurement and let CML Compiler do the rest:

Automated and reproducible generation of version-controlled CMLs
Structured input with template and data validation
Automated test case generation
Supports multiple source data formats including .mat and .json

IP Protected INTERCONNECT and Verilog-A Models from a Single Data Source

Generate Verilog-A and INTERCONNECT from a single data source using characterization data augmented by simulation data

When characterization data is not available or not possible, augment using Lumerical’s industry-leading 3D component-level simulation tools
Generate both fixed and parameterized elements
Augment rich existing set of models with your own custom models
Offers IP protection through CML encryption

CMLs Support Multiple EPDA Workflows

Generate high-quality CMLs from a single data source that can be used in multiple EPDA tools and workflows:

The industry’s only offering of cross-simulator Verilog-A photonic models
Co-simulate using Lumerical’s photonic integrated circuit simulator with 3rd party electrical simulation tools

High-Quality Compact Models

Comprehensive model set offers high accuracy and optimized efficiency in the time and frequency domain
Automatically generated QA tests ensures models accurately predict measured performance
Has been extensively used to generate CMLs for production foundry PDKs including those from AIM Photonics, CompoundTek, imec and TowerJazz

Statistical Support

Generates statistically enabled compact model libraries
Generated CML can be loaded in INTERCONNECT and Virtuoso for Monte Carlo and Corner analysis
Encrypts statistical model data to protect foundry IP

“Protecting the IP of Hewlett Packard Enterprise (HPE) and our foundry partners is critical … and CML Compiler allows us to do so by its inherent encryption and seamless integration into modern EDA simulation tools” Ashkan Seyedi, HPE

“Our customers use both Verilog-A and Lumerical INTERCONNECT at various stages of their designs and it is critical that they give consistent results, as CML Compiler enables” K.S. Ang, CompoundTek

“The Verilog-A models produced by the Lumerical CML Compiler leverage the same data that is used to create the optical models for Lumerical INTERCONNECT, ensuring consistency of simulation results, regardless of the simulation approach” Gilles Lamant, Cadence
