Classification: CPC G | IPC G

Claim 11:
12. An integrated circuit design system comprising:
a computer having a processor and memory;
a software application, run by the computer processor, and residing in the computer memory;
the software application comprising a plurality of software modules comprising:
a place and route module configured to receive a photonically-enabled integrated circuit design and to place a grating coupler of the received photonically-enabled integrated circuit design in an allocated location on a semiconductor substrate;
a physical layout generation module coupled to a predefined layout model and configured to:
receive a parametrized wavelength of an optical beam, a parametrized first refractive index of the grating coupler, and a parametrized second refractive index of a cladding layer;
receive a parametrized taper length of the grating coupler, a parametrized width of the grating coupler, a parametrized grating length of the grating coupler, and a parametrized incident angle of the optical beam incident onto the grating coupler;
generate a physical layout for the grating coupler based on the received parametrized wavelength, the parametrized first refractive index, the parametrized second refractive index, the parametrized taper length, the parametrized width, the parametrized grating length, and the parametrized incident angle and the predefined model; and
a routing module configured to output a physical layout of the photonically-enabled integrated circuit design for manufacturing under a semiconductor fabrication process.
