Description

Electronic chip internal voltage distribution method and system

Technical field

The present invention relates to the field of electronics, and in particular, to a method and system for voltage distribution inside an electronic chip.

Background technique

Chip, English is Chip; Chipset is Chipset. The chip generally refers to the carrier of the integrated circuit, and is also the result of the integrated circuit after being designed, manufactured, packaged, and tested. It is usually an independent whole that can be used immediately. The words "chip" and "integrated circuit" are often mixed. For example, in the common discussion topic, integrated circuit design and chip design say that the chip industry, the integrated circuit industry, and the IC industry are often also meanings. . In fact, these two words are related and different. Integrated circuit entities often exist in the form of chips, because narrowly defined integrated circuits emphasize the circuit itself, such as a phase-shifted oscillator that is simply connected with only five components. When it is still on the drawing, we It can also be called an integrated circuit. When we want to use this small integrated circuit for application, it must be a separate piece of real object, or embedded in a larger integrated circuit, relying on the chip to play its role; Focusing on the design and layout of the circuit, the chip emphasizes the integration, production and packaging of the circuit. The generalized integrated circuit, when it comes to the industry (different from other industries), can also contain various meanings related to the chip.
