Before diving into the manual, you must understand what RSoft CAD actually controls. Unlike generic EDA tools, RSoft CAD is optimized for and finite-difference time-domain (FDTD) simulations. rsoft cad manual
The most powerful feature of the RSoft CAD is the use of variables. Instead of entering "0.5 microns" for a waveguide width, you should define a variable like w_core = 0.5 . This allows you to perform automated parameter sweeps and optimizations without manually redrawing the structure. : Set up variables for dimensions and material
