This application provides an OPC model training method and an OPC model training device, relating to the field of model training technology. The method includes: cutting a chip design layout file to obtain multiple basic blocks; adding noise to the multiple basic blocks to obtain multiple noisy blocks; training a graph generator based on the multiple noisy blocks and corresponding real noise; using the graph generator to generate multiple test graphs based on multiple preset noise vectors; and training the model based on the multiple test graphs to obtain an OPC model. By training the graph generator based on the multiple noisy blocks and corresponding real noise, the graph generator implicitly learns the data distribution of the graphs, that is, it learns the rules of chip design. This results in multiple test graphs generated by the graph generator having more diverse forms and conforming to design rules. The OPC model trained based on these multiple test graphs is also more accurate and reliable.

Edge plug-in connection system of a modular toy and method of construction thereof
This invention provides an edge-plugging connection system for modular toys and its construction method. The system includes at least two assembly modules, each with an edge face featuring an opening and a plugging space. Adjacent assembly modules interlock via their respective edge face plugging structures, with the inner wall of the plugging space forming a surface contact with the corresponding module's plate and edge face, achieving multi-directional rigid constraint and self-supporting detachable connection. After multiple modules are sequentially plugged in, the supporting contact surfaces connect along the structural extension direction to form a continuous force path, allowing external loads to be transmitted and dispersed in an orderly manner along this path, forming a self-stabilizing spatial structure system that can be constructed as a load-bearing structure, climbing structure, or dynamic movable structure. This invention achieves multi-directional rigid constraint, stable force transmission, and strong load-bearing capacity solely through its own structure, solving the problems of discontinuous force transmission paths and insufficient self-stability caused by existing technologies relying on additional connectors or elastic clamps.
