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 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.
Eshraghian was the co-author of 6 influential books in his field such as Basic VLSI and Principles of CMOS VLSI Design: A Systems Perspective. He is the author and/or co-author of more than 200 articles in scientific journals, proceedings of international conferences and symposia.
Engineer using an early IC-designing workstation to analyze a section of a circuit design cut on rubylith, circa 1979. Integrated circuit design, semiconductor design, chip design or IC design, is a sub-field of electronics engineering, encompassing the particular logic and circuit design techniques required to design integrated circuits, or ICs
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).
Here, data structures and data flows are defined. In the geometric view, the design step of the floorplan is located. The logical level is described in the behaviour perspective by boolean equations. In the structural view, this is displayed with gates and flip-flops. In the geometric domain, the logical level is described by standard cells.
In the early days of VLSI, a chip consisted of a few thousand logic circuits that performed a simple function at speeds of a few MHz. Design closure was simple: if all of the necessary circuits and wires "fit", the chip would perform the desired function. Modern design closure has grown orders of magnitude more complex.
