A computer-implemented method for creating an integrated circuit, IC, test engine for testing a proposed IC memory array using new memory structural model. An IC designer inputs the number of words that can be stored and a column multiplexer ratio in a proposed IC memory array. A selection of one or more procedures is made from a library of computer-readable procedures. Each of the procedures is to produce one or more structural primitives that describe certain physical layout features of the proposed IC memory array, without analyzing a CAD layout file of the proposed IC memory array. The library of procedures as a whole translates between a physical model of a family of IC memory arrays and a user interface model of the family. A data background, DB, pattern is produced to be used by the test engine in testing the proposed IC memory array. This is done by executing the selected one or more procedures, wherein these procedures take as input the received number of words and column multiplexer size. Other embodiments are also described.
