A system for automatic recording and prediction of design quality metrics

We present recent extensions to METRICS [10] infrastructure that allow optimization of design processes at the flow level, rather than only at the individual tool level. As previously reported, METRICS infrastructure allows automatic recording of design and process information. Our extensions include (i) the collection of design Row information for use in flow optimization, and (ii) integration with datamining tools to allow automatic generation of design and flow QOR predictors. Our flow optimization experiments try to optimize incremental multilevel FM partitioner runs in an incremental (ECO-oriented) design flow. We also demonstrate QOR predictors that are generated automatically from the METRICS data warehouse by the Cubist datamining tool for industry placement, dock tree generation, and routing tools.
