The invention relates to the technical field of circuit
layout optimization, in particular to a low-EMI
synchronous circuit layout optimization system which comprises a
signal analysis module, a
layout adjustment module, a resource matching module, a task execution module and a
process optimization module. According to the invention, through
difference analysis of high-frequency and low-frequency
signal paths and extraction of an interference intersection dense area, accurate positioning and quantitative management of an
electromagnetic interference source are realized, a potential interference
risk area in a circuit is effectively identified, determination is carried out in combination with
coupling characteristics of component arrangement spacing and
signal line trend, the identification efficiency is improved, and the identification accuracy is improved. The positions of components are accurately adjusted through an overlapping matching mode of resource positions and adjustable areas, the signal
crosstalk and
radiation risks are reduced, the task load proportion and the scheduling time interval trend are combined, the
design process node configuration sequence is optimized, the response capability of layout adjustment and the execution priority matching precision are improved, and the layout adjustment efficiency is improved. Therefore, the cooperative improvement of the interference suppression effect and the design efficiency is realized.
