Physical Design and optimization method of a feedthrough signal line based on low-power integrated circuit

In view of the contradiction between the optimization of chip area and the closure of signal timing in the physical design of low-power Integrated Circuit, by planning the input and output signals and calculating the resource of routing channel, as well as a deep understanding of the global macro unit of the chip, a new way to design and implement the signal line is proposed, which not only satisfies the demand of the chip's compressed area cost, but also satisfies the timing optimization of the key input and output signals, it lays a solid foundation for further improving the performance of the chip in the later period.
