New Support for Multimode Simulations for PICs
Most Photonic Integrated Circuits (PIC) are designed with fundamental modes. However, applications for multimode silicon photonics are on the rise. These applications include mode-division multiplexing, multimode coupling, on-chip nonlinear photonics, on-chip polarization handling devices and multimode gratings, and quantum photonics. To be able to model multimode photonic applications, the photonic simulators need to evolve from supporting few modes (TE, TM and crosstalk) to supporting multimode simulation, analyses and visualization.
- Synopsys OptSim 2022.06 adds new model templates and modeling capabilities as enumerated below to facilitate multimode PIC simulations:
- Additional model templates for:
- Mode Adder
- Mode Splitter
- Mode Combiner
- Polarized Mode Splitter
- Polarized Mode Combiner
- New multimode support in the Waveguide model template
- New multimode support in the Multiport Optical Device Bidirectional model template
Added Support for Monte Carlo Analyses
Variations in manufacturing processes and component parameters require rigorous Monte Carlo analyses in order to get realistic estimates of the yield and commercial viability of the design. The Synopsys OptoCompiler platform provides powerful capabilities for Monte Carlo and corner analyses. Since traditional CMOS designers are a key user group of electronic-photonic design automation (EPDA), it is necessary to augment the design experience by providing EDA-like Monte Carlo features to the design flow. Synopsys OptSim v2022.06 adds a new support for statistical expressions during Monte Carlo simulation (e.g., UNIF, AUNIF, GAUSS, AGAUSS, LIMIT) in Synopsys OptoCompiler.
Enhancements to Electronic-Photonic Co-Simulation
Synopsys OptoCompiler and the Synopsys PrimeWave design environment provide designers with seamless schematic entry and simulation setup for both electronics and photonics on the same chip or combination of chips. Designers choose a desired Synopsys PrimeSim electrical simulator (e.g., Synopsys PrimeSim Spice or PrimeSim HSPICE) for co-simulation with Synopsys OptSim. Synopsys OptoCompiler v2022.06 extends co-simulation support to schematics with multi-level, mixed-domain hierarchies including electronic and photonic devices.
