Abstract
A method includes specifying a target memory macro with one or more parameters, finding function-blocks in the target memory macro, and determining failure rates of the function-blocks based on an amount of transistors and area distributions in a collection of base cells. The method includes generating a failure-mode analysis for the target memory macro, from a memory compiler, based on the failure rates of the function-blocks. The method includes determining a safety level of the target memory macro, based upon the failure-mode analysis of the target memory macro.
