Design method of repeater chip

Abstract

The invention provides a design method of a repeater chip, wherein the designed repeater chip can realize the interconnection of joints and the functions of receiving, classifying, storing, transmitting, sequencing and transmitting message sequences of the repeater chip so as to achieve the effective extension of high-speed transmission links among the joints to reduce the design difficulty and the design risk of hardware. The repeater chip structurally consists of an interface detection unit, a sequence storage unit, a sequence transmission unit, a sequence judgment unit and a sequencing unit. According to the design method of the repeater chip, disclosed by the invention, the integration of multipath processors or multi-joint interconnection systems is realized, the wire arrangement of the hardware with high design difficulty is achieved effectively, and the problem of interconnection wiring design difficulty and design risk in a multipath CPU (central processing unit) system is effectively solved; and the repeater chip has the sky-high application value in an interconnected joint system with maximum PCB (printed circuit board) wiring difficulty, can effectively prolong the wiring length of interconnected joints, meets the requirements of a wiring rule, greatly reduces the wiring complexity of the hardware and reduces the design difficulty and the design risk of the PCB.

Description

technical field [0001] The invention relates to the fields of high-end server design and large-scale integrated circuit design, in particular to a design method of a repeater chip. Background technique [0002] With the rapid development of computer technology and integrated circuit technology, in order to meet the needs of economic and social development, multi-channel computer systems or multi-node interconnection systems have become one of the bottlenecks restricting the key areas of social development. Information fields such as huge data calculation and data analysis, complex graph analysis and scientific budgeting have extremely high requirements on the performance of computer systems. Therefore, it is necessary to build a huge multi-channel computer system in order to better adapt to the application requirements in various fields today, but on the other hand, it is also caught in the technical difficulties of interconnecting multi-channel computer systems. The limited...

Therefore, it is necessary to build a huge multi-channel computer system in order to better adapt to the application requirements in various fields today, but on the other hand, it is also caught in the technical difficulties of interconnecting multi-channel computer systems. The limited PCB area is multi-channel or multi-node interconnection. The design of the interconnection system brings difficulties. At the same time, the high-speed interconnection system also design specifications for the transmission length of the link, which further increases the difficulty of the design of the node interconnection system.
