Database driven place and route for coarse-grain reconfigurable architectures

Abstract

This application provides an example method, an example system, and an example non-transitory computer-readable medium for database driven place and route. One example method includes receiving an unplaced unit graph. The example method also includes classifying the unplaced unit graph against a database of previously placed reference unit graphs using a graph neural network (GNN) to identify a nearest matching previously placed reference unit graph of the database. The example method further includes placing configurable units of the unplaced unit graph onto positions in a configurable units array based on placement position attributes of at least a portion of configurable units of the nearest matching previously placed reference unit graph. The example method also includes generating configuration data that enables the configurable units array to execute at least a portion of the unplaced unit graph.
