Abstract: A dynamic memory management method for layout verification tools that maximizes main memory usage and minimizes required disk storage capacity. Layout data generated during each given geometric operation is retained in main memory at the end of the given geometric operation.

Layout data file(s) are then selected based on minimizing the amount of transferred layout data needed to provide the required estimated amount. A Distributed File Manager then transfers the selected layout data file(s) from main memory to disk storage, thereby facilitating execution of the current geometric operation at peak operating speed.
