VLSI layout of an inverter circuit using Magic software. Magic is an electronic design automation (EDA) layout tool for very-large-scale integration (VLSI) integrated circuit (IC) originally written by John Ousterhout and his graduate students at UC Berkeley. Work began on the project in February 1983.
Another approach is deductive verification. [5] [6] It consists of generating from the system and its specifications (and possibly other annotations) a collection of mathematical proof obligations, the truth of which imply conformance of the system to its specification, and discharging these obligations using either proof assistants (interactive theorem provers) (such as HOL, ACL2, Isabelle ...

The Universal Verification Methodology (UVM) is a standardized methodology for verifying integrated circuit designs. UVM is derived mainly from OVM (Open Verification Methodology) which was, to a large part, based on the eRM (e Reuse Methodology) for the e verification language developed by Verisity Design in 2001.
The VLSI Project was a DARPA-program initiated by Robert Kahn in 1978 [1] that provided research funding to a wide variety of university-based teams in an effort to improve the state of the art in microprocessor design, then known as Very Large Scale Integration (VLSI).
Historically, one way to check the equivalence was to re-simulate, using the final netlist, the test cases that were developed for verifying the correctness of the RTL. This process is called gate level logic simulation. However, the problem with this is that the quality of the check is only as good as the quality of the test cases.
The Electric VLSI Design System is an EDA tool written in the early 1980s by Steven M. Rubin. [ 3 ] [ 4 ] [ 5 ] Electric is used to construct logic wire schematics and to perform analysis of integrated circuit layout.
This check is typically run after a metal spin, where the original and modified database are compared. This is done to confirm that the desired modifications have been made and no undesired modifications have been made by accident. This step involves comparing the two layout databases/GDS by XOR operation of the layout geometries.
