EDA pad package library updating/application method and system, medium and terminal

An EDA pad package library updating system, comprising:

• an extraction module for extracting a graphic data of a pad and setting information of a component based on the pad from an EDA wiring data, wherein the setting information of the component based on the pad comprises a placement angle of the component in the pad;
• a query download module for querying and downloading a graphic model of the component according to attribute information of the component;
• a simulation module for forming a simulated package pad by simulating and assembling the graphical model of the component and the graphical data of the pad according to the setting information of the component based on the pad, by drawing the graphical model of the component onto the pad according to the placement angle of the component in the pad, wherein in response to determining the placement angle cannot make all pins of the component hit the pad, the placement angle is first adjusted by 90 degrees to see if all the pins hit the pad;
• and then in response to determining the adjusted placement angle still cannot make all the pins hit the pad, the adjusted placement angle is adjusted in increments of 1 degree until all the pins hit the pad;
• a storage module for storing the simulated package pad in a model database;
• and
• an association module for updating an existed EDA pad package library by associating the simulated package pad to a predetermined keyword/words in the model database.
