Electronic design automation is used extensively to ensure that designers do not violate design rules; a process called design rule checking (DRC). DRC is a major step during physical verification signoff on the design, which also involves LVS ( layout versus schematic ) checks, XOR checks, ERC ( electrical rule check ), and antenna checks.
Physical verification is a process whereby an integrated circuit layout (IC layout) design is verified via EDA software tools to ensure correct electrical and logical functionality and manufacturability. Verification involves design rule check (DRC), layout versus schematic (LVS), XOR (exclusive OR), antenna checks and electrical rule check ...
A successful design rule check (DRC) ensures that the layout conforms to the rules designed/required for faultless fabrication. However, it does not guarantee if it really represents the circuit you desire to fabricate. This is where an LVS check is used.
CircuitMaker supports design rule configuration and real time design rule checking. Some advanced features, including differential pair routing, interactive length tuning, [23] and polygon pour management, are also available. [24] Production files can be exported directly, although an external Gerber viewer must be used to check the exports.
DipTrace is a proprietary software suite for electronic design automation (EDA) used for electronic schematic capture and printed circuit board layouts. DipTrace has four applications: schematic editor, PCB editor with built-in shape-based autorouter and 3D preview, component editor (schematic symbol), and pattern editor (PCB footprint).
PCB-Investigator provides features for PCB design and manufacturing, supporting various file formats like ODB++, Gerber, and IPC-2581. [6] It includes tools for design rule checks (DRC) and other analyses to verify compliance with industry standards. The software also offers 3D visualization of PCBs and supports scripting for task automation ...
OrCAD PCB Designer is a printed circuit board designer application, and part of the OrCAD circuit design suite. [26] PCB Designer includes various automation features for PCB design, board-level analysis and design rule checks (DRC). The PCB design may be accomplished by manually tracing PCB tracks, or using the Auto-Router provided.
In integrated circuit design, physical design is a step in the standard design cycle which follows after the circuit design.At this step, circuit representations of the components (devices and interconnects) of the design are converted into geometric representations of shapes which, when manufactured in the corresponding layers of materials, will ensure the required functioning of the components.
