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. According to this model, the development of hardware is perceived within ...
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 telecommunication technologies.
In VLSI design, the H tree may be used as the layout for a complete binary tree using a total area that is proportional to the number of nodes of the tree. [3] Additionally, the H tree forms a space efficient layout for trees in graph drawing , [ 4 ] and as part of a construction of a point set for which the sum of squared edge lengths of the ...
Bottom–up and top–down design. Bottom–up and top–down are both strategies of information processing and ordering knowledge, used in a variety of fields including software, humanistic and scientific theories (see systemics ), and management and organization. In practice they can be seen as a style of thinking, teaching, or leadership.
High-level synthesis ( HLS ), sometimes referred to as C synthesis, electronic system-level (ESL) synthesis, algorithmic synthesis, or behavioral synthesis, is an automated design process that takes an abstract behavioral specification of a digital system and finds a register-transfer level structure that realizes the given behavior. [ 1][ 2][ 3]
The rectilinear Steiner tree problem, minimum rectilinear Steiner tree problem ( MRST ), or rectilinear Steiner minimum tree problem ( RSMT) is a variant of the geometric Steiner tree problem in the plane, in which the Euclidean distance is replaced with the rectilinear distance. The problem may be formally stated as follows: given n points in ...
Standard cell. A rendering of a small standard cell with three metal layers ( dielectric has been removed). The sand-colored structures are metal interconnect, with the vertical pillars being contacts, typically plugs of tungsten. The reddish structures are polysilicon gates, and the solid at the bottom is the crystalline silicon bulk.
VLSI Project. 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). The VLSI Project is one of the most influential research ...
