Abstract

A method includes specifying a target memory macro, and determining failure rates of function-blocks in the target memory macro based on an amount of transistors and area distributions in a collection of base cells. The method also includes determining a safety level of the target memory macro, based upon a failure-mode analysis of the target memory macro, from a memory compiler, based on the determined failure rate.
