Give a formal or descriptive definition for each of the following terms. 、ITRS：International Technology Roadmap for Semiconductor. 、Gate-Equivalent：It’s used to measure the basic unit of the complexity of the digital circuit, and based on to complete a circuit function, the number of logic gates are independent of each other.A gate equivalent stands for a unit of measure which allows specifying manufacturing-technology-independent complexity of digital electronic circuit. 、Technology Nodes：A Technology Nodes is defined as the ground rules of a process governed by the smallest feature printed in a repetitive array. 、Feature size：A single graphic minimal size.The minimum scale in integrated circuit devices.roughly half the length of the smallest transistor. 、IC design complexity sources：It contains chip size, power dissipation, heterogeneity, variability and reliability. 、Behavioral representation：It represents a design as a black box and describes its outputs in terms of its inputs and times.It indicates no geometrical information or structural information and takes the forms of textual,mathematics,or algorithmic description. 、Abstraction hierarchy：Abstraction hierarchies are a?human?invention designed to assist people in engineering very complex systems by ignoring unnecessary details. A set of interrelated representation levels that allow a system to be represented in varying amounts of detail. 、IC design：A design is a set of transformations from one representation of a system to another until a representation that can be fabricated exists.Integrated circuit design involves the creation of electronic components, such as? HYPERLINK /wiki/Transistors \o Transistors transistors,? HYPERLINK /wiki/Resistors \o Resistors resistors,? HYPERLINK /wiki/Capacitors \o Capacitors capacitors?and the metallic? HYPERLINK /wiki/Interconnect \o Interconnect interconnect?of these components onto a piece of semiconductor, typically? HYPERLINK /wiki/Silicon \o Silicon silicon. 、Synthes
