A pipeline of programmable serial neighborhood stages is used to automatically check for adherence to a set of predetermined geometrical constraints or design rules used in the fabrication of electronic components such as integrated circuit devices. In a disclosed embodiment, bit-map representations of several IC masks are superimposed in one composite image matrix for processing in the pipeline. Advantages in processing speed, especially for design rule checking requiring data from more than one mask, are obtained since all necessary data is available to the stages in the pipeline.
