Abstract:
A computer implemented method for generating a netlist for a memory comprising:a) acquiring a set of user inputs describing parameters of the netlist through a graphical user interface, wherein the parameters comprise an array size, a defect rate, and a leaf cell design and wherein the memory comprises redundant circuitry comprising redundant data paths and redundant address paths for redundant columns;b) generating one or more leaf cells from a subset of the user inputs; andc) automatically generating, from the leaf cells, a design database for the netlist from the user inputs, wherein the design database reflects physical hierarchies of the netlist, and wherein the step of automatically generating further comprises the steps of; i) automatically generating redundant circuitry when the memory contains at least 256 K bits, and ii) automatically generating redundant circuitry when a user input has met a predetermined value.
