The Mead–Conway VLSI chip design revolution, or Mead and Conway revolution, was a very-large-scale integration design revolution starting in 1978 which resulted in a worldwide restructuring of academic materials in computer science and electrical engineering education, and was paramount for the development of industries based on the application of microelectronics.
Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions or billions of MOS transistors onto a single chip. VLSI began in the 1970s when MOS integrated circuit (metal oxide semiconductor) chips were developed and then widely adopted, enabling complex semiconductor and telecommunications technologies.

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. It can also handle hardware description languages such as VHDL and Verilog.
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.
In 1985, as design shifted to VLSI, Gateway Design Automation introduced Verilog, and Intermetrics released the first completed version of the VHSIC Hardware Description Language . VHDL was developed at the behest of the United States Department of Defense's Very High Speed Integrated Circuit Program (VHSIC), and was based on the Ada ...
Technology files and design rules are essential building blocks of the integrated circuit design process. Their accuracy and robustness over process technology, its variability and the operating conditions of the IC—environmental, parasitic interactions and testing, including adverse conditions such as electro-static discharge—are critical in determining performance, yield and reliability.
