The layout versus schematic (LVS) is the class of electronic design automation (EDA) verification software that determines whether a particular integrated circuit layout corresponds to the original schematic or circuit diagram of the design.
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 ...

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.
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.
Layout Versus Schematic (LVS) – Also known as schematic verification, this is used to verify that the placement and routing of the standard cells in the design has not altered the functionality of the constructed circuit. Design rule checking (DRC) – Also sometimes known as geometric verification, this involves verifying if the design can ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
A circuit design language (CDL) is a kind of netlist, a description of an electronic circuit. [1] It is usually automatically generated from a circuit schematic. It is used for electronic circuit simulation and layout versus schematic (LVS) checks. It is similar to SPICE netlists, but with some extensions.
