Abstract
In one aspect, QoR metrics for different candidate macro placements are estimated using machine learning models. A set of candidate macro placements of hard macros within a circuit design is assessed by estimating a quality metric for each candidate macro placement, as follows. Model-specific estimates of the quality metric are predicted by applying different machine learning models to the candidate macro placements. The different machine learning models are trained using sets of completed macro placements for other circuit designs. The model-specific estimates of the quality metric are combined based on an applicability of (a) the set of macro placements used to train that model to (b) the set of candidate macro placements being evaluated.
