Abstract
A method and system are provided for tuning parameters of a synthesis program for a design description. The method includes (a) ranking individual parameter impact by evaluating a design-cost function of each of the parameters. The method further includes (b) creating a set of possible parameter combinations that is ordered by an estimated-cost function. The method additionally includes (c) selecting, from the set of possible parameter combinations, top-k scenarios having best estimated costs to form a potential set, and running at least some of the top-k scenarios in parallel through the synthesis program. The method also includes (d) repeating steps (b)-(c) for one or more iterations until at least one of a maximum iteration limit is reached and an exit criterion is satisfied.
