METHOD AND SYSTEM FOR DESIGN SELECTION BY INTERACTIVE VISUALIZATION

摘要

A method and system for electronic circuit design selection by interactive visualization. The present invention is particularly appropriate for learning the performance and behaviour of analog circuits, and for selecting a preferred design from a dataset of candidate designs derived from a multi-objective optimization. The method consists of providing a multidimensional dataset from a multiobjective optimization, or otherwise. The multidimensional dataset is then displayed as a plurality of plots. The plots can be one-dimensional, or multi-dimensional, and can include parallel coordinate plots. By modifying at least one of the plots, the user can interactively select an evaluation dataset for further evaluation or testing. The modification can take the form of interactive filtering to reduce the dataset in a desired manner. Typically, this is done through a graphical interface, by visual selection, brushing, etc. It can also include defining or constructing constraints of one or more variables in the multidimensional dataset. The constraints can include linear and non-linear. This modification and selection process can be repeated as necessary to further restrict the dataset to a manageable number of candidate designs.
