Disclosed is an approach to implement snapping techniques that aid the interactive, assisted, or automatic placement of layout instances or groups of layout instances for generating a legal placement layout while reducing or entirely eliminating any subsequent or separate performance of design rule checking with respect to the relevant design rules, constraints, or requirements governing the legality of the instances or groups of instances placed in the placement layout.

Method, system, and computer program product to implement snapping for an electronic design

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing decision models. In one aspect, a method includes providing data that cause presentation of a model development user interface receiving first model rule data through the user interface. The first model rule data specify a first characteristic of a violating resource and a threshold score for the first characteristic. Additional model rule data are received through the user interface. The additional model rule data specify one or more additional model rules. Relationship data are received through the user interface for each of the additional model rules. The relationship data specify sets of the additional model rules that violating resources satisfy. Data that cause a hierarchical presentation of the first model rule and the additional model rules are provided.
