September 3, 2004 Ossining, NY -- RSoft Design Group Inc. has announced its membership in Cadence Design Systems, Inc.'s Connections Program and the development of the OptSim Electrical Circuit Model Generator for Cadence Vituoso Circuit Simulator. RSoft Design Group will design advanced interfaces to Cadence's products for electronic circuit design and simulation.
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 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 the Virtuoso Spectre Circuit Simulator to be used 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 is expected to reduce 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, says RSoft.
