A key feature of the RSoft CAD is its use of symbolic variables. Rather than entering static numerical values for lengths or widths, users can define variables (e.g., "width = 0.5"). This allows for easy parametric sweeps and optimization, as changing a single variable updates all dependent objects in the design.

Proper grid spacing is vital. A rule of thumb is to have at least 10–20 grid points per wavelength inside the material. Boundary Conditions (BCs):
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.
You can directly import mask files in CIF, DXF, and GDS-II formats, or export your designs for fabrication.
