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.
By the early 1990s, VLSI had not been timely in adopting a 1.0 μm manufacturing process as the rest of the industry moved to that geometry in the late 1980s. VLSI entered a long-term technology partnership with Hitachi and finally released a 1.0 μm process and cell library (actually more of a 1.2 μm library with a 1.0 μm gate).
The Gajski–Kuhn chart (or Y diagram) depicts the different perspectives in VLSI hardware design. [1] Mostly, it is used for the development of integrated circuits. Daniel Gajski and Robert Kuhn developed it in 1983. In 1985, Robert Walker and Donald Thomas refined it.
This process was aided by the recent introduction of depletion mode NMOS logic, which greatly simplified the conceptual model of the active elements. [6] The mid-1970s were a period of rapid change as new processes were being introduced at different companies at a rapid pace. Each new process led to a set of design rules that often ran to 40 pages.
Python 2.0 was released on October 16, 2000, with many major new features, such as list comprehensions, cycle-detecting garbage collector (in addition to reference counting) and reference counting, for memory management and support for Unicode, along with a change to the development process itself, with a shift to a more transparent and ...
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.
The Tcl programming language was created in the spring of 1988 by John Ousterhout while he was working at the University of California, Berkeley. [14] [15] Originally "born out of frustration", [11] according to the author, with programmers devising their own languages for extending electronic design automation (EDA) software and, more specifically, the VLSI design tool Magic, which was a ...
