OSSINING, N.Y. –- RSoft Design Group, Inc. announced today its membership in Cadence Design Systems, Inc.'s Connections Program and the development of the OptSim™ Electrical Circuit Model Generator™ for Cadence Virtuoso® Circuit Simulator. RSoft Design Group, a leader in modeling, simulation, and design tools for the photonics, optoelectronic components, semiconductor, and optical communications industries will design advanced interfaces to Cadence's industry-leading products for electronic circuit design and simulation. The semiconductor, photonics, and optical communications industries will benefit by improved time-to-market and lowered costs through this unprecedented integration.

The first product interface to be developed by RSoft through the Cadence Connections Program is the OptSim Electrical Circuit Model Generator for Virtuoso Spectre Circuit Simulator. An application of this new tool is modeling a semiconductor laser. Semiconductor lasers, including VCSELs, can be modeled very accurately in OptSim based on manufacturer data sheets, measured data, or simulation results from a device-level laser simulator such as RSoft's LaserMOD™. This model can output to Virtuoso Spectre Circuit Simulator to be utilized in laser driver circuit simulations that include accurate semiconductor laser performance characteristics. Accurate laser models are important for laser driver circuit simulation and design because of the tight nonlinear coupling between semiconductor lasers and the laser driver circuit, as well as the strong impact the final output optical waveform from the laser has on overall optical link system performance.

This new capability to include accurate laser models in laser driver circuit simulations represents a major advancement in reducing the time-to-market and overall product costs for laser driver manufacturers. Users will benefit from the most accurate overall simulation across both circuit and system-level. This breakthrough mixed-level simulation accuracy is critical for optimizing the component design as well as the system design for laser drivers, semiconductor lasers including VCSELs and optical communication systems.
