发明名称 Method and System for Verifying Performance of an Array by Simulating Operation of Edge Cells in a Full Array Model
摘要 A method and system for verifying performance of an array by simulating operation of edge cells in a full array model reduces the computation time required for complete design verification. The edge cells of the array (or each subarray if the array is partitioned) are subjected to a timing simulation while the center cells of the array are logically disabled, but remain in the circuit model, providing proper loading. Additional cells are specified for simulation if calculations indicate a worst-case condition due to a non-edge cell. Wordline arrivals are observed to determine worst-case rows for selection. For write operations, the difference between the wordline edges and the data edges is used to locate any non-edge "outlier" cells. For read operations, the wordline delays are summed with the bitline delays determined from edge column data to locate any outliers.
