The application discloses an excitation automatic generation method and system and a computer readable medium, and relates to the technical field of electronic design. The method comprises the following steps: based on a pre-acquired test case file, a target test case is acquired from a plurality of pre-stored test cases; case key information of the target test case is acquired, and the case key information is used for representing basic signals to be simulated by the target test case; and based on the case key information, an excitation signal is generated. Therefore, in the face of different target test cases, a control excitation signal with a unified style is automatically generated based on the case key information of the target test case, thereby reducing the dependence of cases on manual checking of logic functions and manual writing of excitations for the functions, and improving the design and development efficiency of integrated circuits.

This invention relates to the field of tunnel boring machine (TBM) design technology and discloses a tool layout method for a circular cutterhead of a TBM. The method includes: constructing a mathematical model of tool layout incorporating cutting force data from a CSM model; determining the optimization objective and constraints for minimizing eccentric force and eccentric moment; initializing a gray wolf population by mapping discrete permutations to continuous vectors using a continuous encoding strategy and calculating fitness values; executing a global iteration of the gray wolf optimization algorithm, using social hierarchy to guide population updates; embedding a tabu search strategy in the global iteration to perform local neighborhood search on the optimal individual to generate and selectively replace the optimal solution; and finally outputting the tool layout scheme and verifying its feasibility. This invention effectively solves the problem of tool layout easily getting trapped in local optima through the synergistic cooperation of the gray wolf algorithm and tabu search, improving the mechanical balance and solution efficiency of the cutterhead design, and reducing design and production costs.
