DESIGN ANALYSIS TOOL AND METHOD FOR DERIVING CORRESPONDENCE BETWEEN STORAGE ELEMENTS OF TWO MEMORY MODELS

A method and system automatically generates a bit-cell correspondence between a first memory model and a second memory model of a memory. The method includes receiving data from the first and the second memory model, obtaining true-inverted fan-in cones for words in the memory models to obtain correspondence between sets of words in the two models, writing word binary sequences into the words to obtain a set of bit-cell correspondences, and using inherent structural information in memory designs to generalize bit-cell correspondence obtained on bit-cells of a pair of corresponding words to obtain bit-cell correspondence information for all the bit-cells in the memory models. Correspondence is detected if one of the bit-cell binary sequences written into a bit-cell in the first memory model is equal to or an invert of another of the bit-cell binary sequences written into a bit-cell in the second memory model.
