Problems solved by technology

This will make the analysis of the circuit time-consuming in today's increasingly complex circuit architecture.
[0004] In addition, in the existing technical field, designers often only consider the number of registers in the circuit, so the adjustment of the offset value in this way can improve the circuit efficiency is limited

Abstract

The invention provides an adjusting device and an adjusting method for circuit signal offset. The circuit signal offset adjusting method comprises the following steps: providing a controller to execute the following steps: based on each of a plurality of clock signals, segmenting the circuit according to a network link table of the circuit to generate a plurality of circuit partitions; respectively performing clustering action on the circuit partitions to obtain a plurality of circuit clusters; recognizing adjacent states of the layout positions of the circuit groups; and adjusting the offset value of each circuit group according to the adjacent state.

Description

technical field [0001] The present invention relates to a circuit signal skew adjustment device and adjustment method, in particular to a circuit signal skew adjustment device and adjustment method based on a clock tree (clock tree) analysis. Background technique [0002] In the field of circuit design, based on the operation of the circuit, there may be a large number of registers, and a transition phenomenon occurs at the same time, resulting in a situation where the operating voltage is instantaneously and greatly pumped, resulting in a voltage drop. In order to avoid such a situation, it is necessary to adjust the offset value (skew) appropriately in the circuit. [0003] In the existing technical field, the designer needs to consider various variables in the circuit, such as the structure of the clock signal, the power consumption of the circuit, and the layout position of the entity, in order to effectively adjust the offset value. This will make the analysis of the c...
