1. A method performed by a computer system for estimating a trial PPA metric for a memory component design evaluated at a trial design point, the method comprising: receiving the memory component design; receiving a reference PPA (power, performance, area) metric for the memory component design evaluated at a reference design point; accessing a PPA database that contains PPA metrics for test components evaluated at multiple design points; determining, by the computer system, a scale factor for the memory component, the scale factor based on: scaling from (a) the reference design point to (b) the trial design point, of an equivalent test component to the memory component; and applying the scale factor to the reference PPA metric to determine the trial PPA metric at the trial design point, wherein the memory component design is providable for subsequent design and manufacturing of the memory component.
