A waveguide abutment between two sections of the waveguide. A single database unit (DBU) (usually 1В Ојm, or less) difference can introduce a sliver between the facet and as a result significant light reflection, an example of which can be seen in Fig. The main issue of such discontinuity is snapping of the endpoints of the facets of a waveguide to database points (required for manufacturing) in the independent representations. In our case, we must ensure that the methodology we follow guarantees continuity вЂњby abutmentвЂќ across independent mathematical models.

In a system where capacity is not really an issue (like for small design, PC-based systems), it is possible to represent the full design in one mathematical space, resolve the continuity problem in that space, and have to deal with only the discretization of a continuous-by-design mathematical model. The second challenge is accentuated in an EPDA system that targets allowing hierarchical separation of the design elements, as mathematical representations of different elements is done independently. Indeed, the Virtuoso Design Framework offers the ability to integrate a third-party shape generation engine through interprocess communication in addition to allowing users to write their own in SKILL or use built-in functions.Дiscretization of the underlying mathematical model of the design brings two challenges: generating the optimal number of points to represent the curve and ensuring that different element вЂњstitchвЂќ perfectly together. Both approaches have been proven with working design tapeouts. It is, however, possible to plug in alternative shape generation engines into the CadenceвЂ™s Virtuoso Layout Editor Tool suite and have, for example, a different strategy, such as manhattanization of the shapes. CadenceвЂ™s approach, driven by the need for accuracy and precision, supports a methodology that has a mathematical foundation and a discretization algorithm that minimizes error while maintaining the on-grid characteristic of the design. We will review a commercially available approach developed by Cadence (supported for simulation by Lumerical Inc.) to provide a solution. Rich Goldman, in Optical Fiber Telecommunications VII, 2020 5.7.1 Photonics layout: curvilinear, non-Manhattan, and extremes of scaleДЄs stated in the introduction, photonics layout brings into the design platform the need for curvilinear layout. System programming languages such as C, C++, and Javaв„ў are designed to allow programmers to build data structures, algorithms, and-ultimately-applications from the ground up. A component-level netlist refers to a circuit representation at the level of individual components. The netlist will also specify the connections (wires) between the various gates and functions. A gate-level netlist refers to a circuit representation at the level of individual logic gates, registers, and other simple functions. There are a wide variety of programming languages available, but-excepting specialist application areas-the most commonly used by far are traditional C and its object-oriented offspring, C++.

ELECTRONIC SCHEMATIC SOFTWARE VERIFICATION

The term вЂњautomationвЂќ refers to the ability for end-users to augment, customize, and drive the capabilities of electronic design and verification tools by means of a scripting language and associated support utilities. The companies promoting front-end tools for schematic capture and simulation classed them as Computer-Aided Engineering (CAE). These integrated circuit and circuit board layout programs became known as Computer-Aided Design (CAD) tools. Other companies like Racal-Redac, SCI-Cards, and Telesis created equivalent layout programs for printed circuit boards. Over time, these early computer-aided drafting tools evolved into interactive programs that performed integrated circuit layout. The term Electronic Design Automation (EDA) refers to the tools that are used to design and verify integrated circuits (ICs), printed circuit boards (PCBs), and electronic systems, in general.
