Abstract
Aspects of the disclosed technology relate to techniques of generating guiding patterns for via-type feature groups. A guiding pattern is constructed based on seeding positions for a via-type feature group. The initial seeding positions are derived from targeted locations of via-type features in the via-type feature group. A potential energy function is then determined for the guiding pattern. Based on the potential energy function, simulated locations of the via-type features are computed. The seeding positions are compared with the targeted locations and may be adjusted based on differences between the simulated locations and the targeted locations. The above operations may be repeated until one of one or more termination conditions are met.
