1. A layout method, configured to design a layout of a bridging circuit between a source circuit and a destination circuit of a circuit system, comprising:
categorizing the bridging circuit into a plurality of sub-regions according to physical structural characteristics;
obtaining a plurality of default sub-region model units corresponding the plurality of sub-regions from a database;
setting the plurality of default block model units using a plurality of parameters to obtain a plurality of sub-region models;
using an electromagnetic simulation software to extract a plurality of electrical models from the plurality of sub-region models, respectively;
using a circuit simulation software to cascade the plurality of electrical models to obtain an overall electrical model;
evaluating whether the overall electrical model meets a specification requirement for the bridging circuit required by the circuit system; and
when the overall electrical model meets the specification requirement, obtaining a layout rule according to the plurality of sub-region models.
