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.
Comparison: The extracted layout netlist is then compared to the netlist taken from the circuit schematic. If the two netlists match, then the circuit passes the LVS check. At this point it is said to be "LVS clean." (Mathematically, the layout and schematic netlists are compared by performing a Graph isomorphism check to see if they are ...

In the automated design of integrated circuits, signoff (also written as sign-off) checks is the collective name given to a series of verification steps that the design must pass before it can be taped out. This implies an iterative process involving incremental fixes across the board using one or more check types, and then retesting the design.
A process design kit (PDK) is a set of files used within the semiconductor industry to model a fabrication process for the design tools used to design an integrated circuit. The PDK is created by the foundry defining a certain technology variation for their processes. It is then passed to their customers to use in the design process.
In December 2009, a technical subcommittee of Accellera — a standards organization in the electronic design automation (EDA) industry — voted to establish the UVM and decided to base this new standard on the Open Verification Methodology (OVM-2.1.1), [1] a verification methodology developed jointly in 2007 by Cadence Design Systems and Mentor Graphics.
Gradually, electronic design automation automated more and more of the place-and-route work. At first, it merely sped up the process of making many small edits without spending a lot of time peeling up and sticking down the tape. Later design rule checking sped up the process of checking for the most common sorts of errors. Later auto routers ...
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 ...
