. It serves as a unified platform to define material properties and structural geometries for simulation modules like 1. Core Layout and Design Object-Oriented Input

: Unlike standard CAD, RSoft uses specialized photonic objects like straight, tapered, or curved waveguides, lenses, and polygons. Symbolic Variables

: Every parameter (width, position, refractive index) can be defined using arithmetic expressions and variables. This allows you to update an entire design by changing a single variable value. Property Access

: Right-clicking any component allows you to edit its shape information and optical properties, such as refractive index profiles. Katedra mikroelektroniky 2. Essential Documentation Chapters

Based on official manuals, the CAD documentation is typically organized into several key areas: Section 3.G : Detailed instructions for computing and displaying Index Profiles : Coverage of Multi-Physics utilities (e.g., thermal or carrier effects). Chapter 10 : Advanced modeling and layout features. Appendix C : A complete list of valid Arithmetic Operators and functions for variable-based design. Appendix E : Documentation for specialized (e.g., AWG or Solar Cell utilities). 3. Simulation Setup Workflow Define Global Variables

: Set up variables for dimensions and material properties in the Symbol Table. Create Geometry

: Use the toolbar to place objects; their coordinates and properties are linked to your variables. Set Up Launch Fields

: Define the excitation type (e.g., Gaussian, mode-based) required for the specific simulation engine. Add Monitors

: Place monitors to record data such as power, phase, or field profiles during the simulation. Choose Engine : Launch the appropriate engine (e.g., for BPM) directly from the CAD interface.

4. Parametrization and Scripting (COM/API)

For power users, the manual shifts from interactive use to automation. RSoft CAD supports a COM (Component Object Model) interface. The manual includes basic scripts in VB Script and JavaScript to:

• Automatically generate a 2D array of ring resonators.
• Sweep a waveguide width across 100 simulations.
• Batch export layouts to bitmap or GDSII formats.

7.2 Naming Conventions

The manual shows examples like waveguide_1, but professionals use:

• TE0_taper_10um (polarization explicit)
• SWG_etch2 (structure + process step)
• Why: The manual’s "Batch Processor" relies on regex file naming.

Final Verdict: An Indispensable Reference

The RSoft CAD Manual is not a light read—it runs several hundred pages. However, it is the difference between guessing your layout parameters and engineering them precisely. For any serious photonics simulation engineer, this manual deserves a permanent place on the digital bookshelf (and a bookmark on the "Boolean Operations" and "GDSII Import" chapters). rsoft cad manual

Whether you are simulating a simple straight waveguide or a complex photonic crystal, the CAD manual ensures that the virtual structure you build perfectly mirrors the physical device you intend to fabricate.

Navigating the RSoft CAD Manual: A Deep Dive for Photonic Design

The RSoft CAD Environment serves as the central hub for the Synopsys Photonic Device Tools. Whether you are a researcher or an engineer, understanding the manual is the first step toward mastering the design of waveguide devices and optical circuits. 1. The Core Architecture

The manual explains that the CAD environment is more than just a drawing tool; it is a control program for multiple simulation modules. Each algorithm engine shares a common CAD interface, meaning you can design a structure once and toggle between different solvers without re-importing data. Key Simulation Engines Managed via CAD:

BeamPROP: Used for simulating waveguides and fiber applications.

FullWAVE (FDTD): Designed for complex nanotechnology, photonic crystals, and biophotonics.

BandSOLVE: Computes the band structures of photonic bandgap devices.

FemSIM: A finite element method (FEM) tool for mode solving. 2. Powerful Layout Capabilities

The manual details how to build complex structures from the ground up using both graphical and mathematical inputs.

Object-Oriented Design: Each component—whether a straight, tapered, or curved waveguide—can have its own set of properties accessed via a simple right-click.

Mathematical Expressions: A standout feature highlighted in the documentation is the ability to define parameters (like width or position) using arithmetic expressions and user-defined variables. This allows you to modify an entire circuit by changing a single variable.

Hierarchical Layout: You can build intricate structures from smaller, reusable sub-components, making it easier to manage large-scale designs. 3. Advanced Design Features RSoft CAD Environment is the central design interface

For those moving toward fabrication, the CAD manual provides instructions on several essential utilities:

Mask Integration: You can directly import mask files in CIF, DXF, and GDS-II formats, or export your designs for fabrication.

Automated Optimization: The MOST (Multi-Variable Optimization and Scanning Tool) utility allows for automated parameter scanning and virtual prototyping, significantly reducing the need for physical tests.

Material Library: The software includes a library of built-in materials and supports user-defined materials via data files or expressions. 4. Typical Simulation Workflow

According to training guides, the standard "post-CAD" process involves a repeatable loop: Draw Geometry: Use the toolbar to add fundamental objects. Define Parameters: Set material properties and variables.

Run Simulation: Select the appropriate engine (e.g., FullWAVE or BeamPROP).

Analyze Results: Use built-in monitoring tools to view and interpret the output. Conclusion

The RSoft CAD manual is your roadmap for navigating the complexities of photonics. By mastering the object-oriented environment and the integrated simulation engines, you can accelerate your "what if" scenarios and bring your designs to market faster.

7.3 When to Ignore the Manual’s Default Mesh

The manual’s suggested dx = lambda/(20*n) is overly conservative for most silicon photonics (slow). Use dx = lambda/(10*n) for initial sweeps, then refine. The manual admits this in a footnote on page 734.

What RSoft CAD is

RSoft CAD is a layout and design tool within the Synopsys RSoft Photonic Component Design Suite used to create, edit, and export 2D photonic device geometries and mask layouts for simulation and fabrication. It supports drawing primitives, boolean operations, layer management, grid/snapping, text/annotations, and exports common file formats for downstream simulators (e.g., BPM, FDTD) and mask generation.

Summary

The RSoft CAD Manual is more than just a drawing guide; it is a bridge between optical physics and engineering design. Mastery of its contents allows a photonics engineer to move seamlessly from a conceptual device sketch to a fully simulated, optimized component ready for fabrication. Whether you are a beginner setting up your first waveguide or an expert debugging complex boundary conditions, the manual remains the definitive resource for accurate photonic modeling.

The RSoft CAD Environment is the foundational layout and control program for the RSoft Photonic Device Tools suite by Synopsys. It serves as the unified interface for designing optical circuits, waveguides, and other photonic structures before passing them to specific simulation engines.
