The RSoft product family is used to design, optimize and simulate optical telecommunication devices and networks, optical components used in semiconductor manufacturing, and nano-scale optical structures. It enables engineers to design and optimize the optical components and systems found in products such as fiber optic networks, semiconductor lithography equipment, silicon optical chips and LEDs. In addition, the software supports the design, planning and simulation of complete optical telecommunication networks.

RSoft includes the following product suites to allow engineers to quickly make definitive design choices and improve time-to-revenue with greater market acceptance.

RSoft Photonic Component Design Suite 2018.12

The RSoft Photonic Component Design Suite version 2018.12 introduces new features to advance the design of optics used in augmented reality and virtual reality (AR/VR) systems. The latest RSoft release supports Synopsys’ optical design workflow for nano-textured diffractive optical elements that enable smaller, lightweight AR/VR devices with improved displays and immersive experiences.

Synopsys’ design workflow includes a seamless interface between LightTools software for virtual prototyping of light as it traverses optical and mechanical components in an AR/VR model, and the RSoft tools for fast, rigorous modeling of nano-textured optical structures. LightTools and RSoft provide a unique multi-domain simulation approach that shares Bidirectional Scattering Distribution Function (BSDF) data to help AR/VR device designers achieve superior light extraction efficiency, beam shaping, and color tuning.

In version 2018.12, the RSoft BSDF enhancements provide greater design flexibility and speed with:

  • BSDF files that can be calculated for X-, Y-, or Z-oriented structures
  • Support for LightTools zone rotations in RSoft BSDF user-defined optical properties
  • Expanded azimuthal symmetry support for faster RSoft BSDF calculations
  • Support for non-uniform wavelengths, which is useful for RGB color displays in AR/VR systems

RSoft Photonic System Design Suite Version 2017.03

RSoft Photonic System Design Suite Version 2019.03

RSoft Photonic System Design Suite (System Tools) version 2019.03 provides the following updates:

New features in OptSim and ModeSYS include:

  • OptSim
    • Support for probabilistic constellation shaping for coherent systems
    • Miscellaneous improvements and bug fixes
  • ModeSYS
    • New models for large-core fiber-based systems: Large-Core Fiber Injection, Large-Core Fiber Bend, and Large-Core Detector Coupler
    • Miscellaneous improvements and bug fixes

In OptSim™:

  • Addition of Viterbi & Viterbi (V&V) M-th power Carrier Phase Estimation (CPE) algorithm in OptSim DSP Library for MATLAB. The V&V M-th power CPE algorithm helps designers with accurate estimation of carrier phase for QPSK and PM-QPSK modulation formats.
  • Application notes and design files to illustrate new features and industry trends.

In OptSim and OptSim Circuit:

  • Interface between the RSoft OptSim and OptSim Circuit tools and Synopsys’ HSPICE tool for seamless optoelectronic analysis. With over 25 years of successful design tapeouts, HSPICE is the industry’s gold standard electrical circuit simulator and offers foundry-certified electrical MOS device models. The RSoft-HSPICE interface supports precise co-simulation of electronic components in photonic circuits in both on-chip and off-chip optical configurations. RSoft OptSim and OptSim Circuit are the only photonic simulation tools on the market that offer this capability.
  • Application notes and design files to illustrate new features and industry trends.

In OptSim Circuit:

  • Support for PhoeniX Software’s OptoDesigner elastic connectors. Constraints from packaging and design rule checks (DRC) can impose restrictive routing requirements on schematic-driven layouts. To help overcome these constraints, OptSim Circuit supports PhoeniX OptoDesigner elastic connectors, where the shape and dimensions of the connectors are determined through tight integration with layout generation, and equivalent compact models for these connectors are created and simulated in OptSim Circuit.
  • Support for the American Institute for Manufacturing Integrated Photonics (AIM Photonics) Process Design Kit (PDK) version 1.5b and new PDAFlow libraries.
  • Support for the imec Process Design Kit (PDK) version PDK ISIPP50G.

In OptSim, OptSim Circuit and ModeSYS™:

  • Ability to add comments/descriptions to component and user-defined variables. Adding comments and descriptions to user-defined and component variables not only aids collaboration, but also helps the original designer recollect the context and definition of the variables during design reviews.
