Abstract :
High-level synthesis (HLS) tools often use parameterized RT component generators during component selection and allocation. Rapid and accurate technology-specific estimates are therefore crucial for performing effective design space exploration. We describe a fast (on-line) method for estimating the area and delay of regular-structured generic RT components tuned to a particular technology library. The estimation models are generated using a least-square approximation on a set of sample technology data points from selected component implementations. We tested these models against real data points on combinational and sequential components and observed an average error of within 10%. The estimators are integrated with a HLS system to provide on-line technology projection of RT components
