Abstract

The invention discloses a digital integrated circuit wiring method based on binary coding and terminal equipment. The method comprises the following steps: determining a preset number of first connection modes, calculating a first fitness function value of each first connection mode according to a wiring subspace corresponding to each connection line, and processing each first connection mode according to each first fitness function value to obtain each second connection mode; selecting a first number of third connection modes from a set formed by combining the first connection mode and the second connection mode, and respectively calculating a second fitness function value of each third connection mode; and selecting an optimal connection mode from all the third connection modes accordingto all the second fitness function values obtained through calculation, and connecting standard unit pins according to the optimal connection mode. According to the method, binary coding of uniform grids is adopted, so that on one hand, the problem of uncertain coding length in a non-grid algorithm is avoided, the optimization space range is reduced, and the wiring efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of digital integrated circuits, in particular to a digital integrated circuit wiring method and terminal equipment based on binary codes. Background technique [0002] Digital digital integrated circuit (Integrated Circuit, IC), also known as chip, is a microelectronic device based on semiconductor technology. At present, digital digital integrated circuits generally use such as figure 1 The shown design method is based on the standard cell (StandardCell), wherein the standard cell is a simple circuit module containing certain functions, such as flip-flops, gate circuits, adders, buffers, registers, RAM storage units, and the like. In the process of digital digital integrated circuit design, the position of the standard cell is generally laid out according to the connection rate, etc., and then the layout of the connection is designed according to the position of the standard cell, input and output pins, an...
