Clock system construction method, device and clock system

Abstract

The invention provides a construction method and device for a clock system and the clock system. The clock system comprises an isolation area and non-isolation areas which are arranged on a chip territory, clock devices are arranged in the isolation area, non-clock devices are arranged in the non-isolation areas, and comprise at least two loads and at least two triggers, each trigger is connected to the output end of the corresponding load in a coupled, and the at least two loads are arranged in the non-isolation areas in a balanced mode. According to the construction method and device for the clock system and the clock system in the embodiment, the isolation area and the non-isolation areas are divided on the chip territory, it is avoided that other components and parts overturn nearby the clock devices, overturning currents of nearby areas of the clock devices are effectively reduced, the influence of voltage dropping on the clock devices is reduced, and power supply noise is also isolated and prevented; meanwhile, the loads are distributed in a balanced mode, so that the loads have the good symmetries, clock deviations are reduced, and the clock performance is improved.

Description

technical field [0001] The invention relates to an integrated circuit design method, in particular to a clock system construction method, device and clock system. Background technique [0002] With the increasing integration and complexity of the chip, the number of functional modules in the chip is gradually increasing, and each functional module has different requirements for the clock, and the same clock serving the entire chip is no longer applicable. The clock system in the prior art usually consists of two parts: a global clock network and a local clock network. Usually, the clock signal of the global clock network is sent to each local clock network after frequency division, frequency multiplication, phase adjustment and other processing. [0003] The layout and wiring of chip components and metal wires are usually carried out according to the chip function and the design of the clock system. If the deviation increases, the quality of the clock signal will deteriorat...
