Introduction to RSoft CAD Manual

Useful commands and file structure

• xbcad or RSoft CAD Layout — launches CAD GUI.
• Project folders typically contain subdirectories: /docs (manuals), /examples, /readme, /results, /input.
• Printable manuals and help files: the software installs help in a help subdirectory and PDF manuals in a docs subdirectory; example/tutorial files are in /examples.

RSoft CAD Manual — Quick Guide and Overview

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. xbcad or RSoft CAD Layout — launches CAD GUI

The manual isn't just a list of buttons; it is a roadmap for moving from a physical concept to a simulated mathematical model. Here is how it typically guides a user through a design workflow:

1. Geometry Creation: RSoft CAD allows users to create complex geometries using a variety of tools, including 2D and 3D modeling, extrusion, and sweeping.
2. Material Properties: The software provides a comprehensive database of material properties, allowing users to accurately model the behavior of various materials in their designs.
3. Electromagnetic Simulation: RSoft CAD offers advanced electromagnetic simulation capabilities, including finite-difference time-domain (FDTD) and finite element method (FEM) solvers.
4. Post-Processing: The software provides a range of post-processing tools for visualizing and analyzing simulation results, including field plots, spectra, and power flow analysis.
