Compare L-Edit Photonics vs. Oasys-RTL

Create your photonic integrated circuit within a layout-focused workflow that allows designers to utilize either a drag-and-drop interface or a script-based approach. Both methods are facilitated by a comprehensive custom IC design layout editor, which also manages the physical verification and tape-out stages. L-Edit Photonics allows for rapid photonic design creation through its intuitive drag-and-drop functionality, eliminating the need for coding. Upon finalizing the design, a netlist can be generated to support photonic simulations. The PIC design is entirely integrated within an IC layout editor, enabling users to develop layouts without writing any code, thus supporting a layout-centric approach that does not require a schematic. For those who prefer a schematic flow, S-Edit is available as an optional tool. Moreover, a simulation netlist can be produced for input into a photonic simulator, and photonic simulations are seamlessly incorporated through partnerships with various providers. Additionally, multiple foundries offer photonic PDKs to enhance design capabilities. Overall, this comprehensive workflow simplifies the photonic design process while catering to various designer preferences.

Oasys-RTL meets the demand for enhanced capacity, quicker runtimes, elevated quality of results (QoR), and physical awareness by performing optimization at a more abstract level while also incorporating integrated floorplanning and placement features. This tool significantly improves the quality of results by facilitating physical accuracy, efficient floorplanning, and rapid optimization cycles, ensuring timely design closure. Its power-aware synthesis capabilities encompass support for multi-threshold libraries, automatic clock gating, and a UPF-based multi-voltage domain flow. During the synthesis process, Oasys-RTL intelligently inserts the necessary level shifters, isolation cells, and retention registers according to the power intent specified in the UPF framework. Additionally, Oasys-RTL can generate a floorplan directly from the design's RTL by applying dataflow and adhering to timing, power, area, and congestion constraints. It adeptly incorporates regions, fences, blockages, and other physical directives via advanced floorplan editing tools while automatically positioning macros, pins, and pads to optimize the layout. This holistic approach ensures that designers can efficiently manage complex designs and meet stringent performance requirements.
