Disclosed herein is a method of storing data results of simulation processing of a hardware description language (HDL) model based upon keywords. In accordance with the method, result data obtained by simulation of at least one HDL model are received. In association with the result data, a plurality of value sets is received, where each value set includes at least one keyword having an associated value. Each keyword identifies a parameter external to the HDL model that affected the result data. The data results are stored within a data storage subsystem in association with the plurality of value sets such that particular result data are attributable to particular ones of the plurality of value sets. In one embodiment, a keyword table is built in the data storage system that indicates which data subdirectories store result data associated with particular value sets. The result data can then be queried based upon selected keywords of interest, for example, by reference to the keyword table.
