Any Tool. Any Scale. Any Time.
As an ECO tool, Tweaker optimizes a design incrementally and locally, with minimal impact to the existing performance. In all of the ECO fixing operations, Tweaker only focuses on only critical portions of a design, known as the "ECO Domain". For this reason, Tweaker can handle large designs in a very short turn-around time.
Aside from MMMC support, Tweaker is most celebrated for its physical awareness, which is essential to precise RC and timing estimation. In contrast with other timing ECO solutions that lack physical awareness, Tweaker’s ability to analyze and apply physical information produces a reduction in ECO iteration count. In Tweaker’s manual ECO mode, users can see the input physical layout to choose optimal ECO cell locations. As a result, Tweaker consideration of physical information eases communication between a project’s logic team and physical team.
