Abstract
A system and method for evolving configuration bitstreams for a programmable logic device are disclosed. A plurality of data structures having respective sets of data are established. From the sets of data, respective configuration bitstreams are generated, wherein the sets of data are mapped to positions in the bitstreams. The configuration bitstreams are then evaluated for relative suitability to meet predetermined criteria when deployed on a programmable logic device. From the relative suitability of the configuration bitstreams, next-generation data for the data structures are generated using a genetic algorithm applied to sets of data. In the various embodiments, the configuration bitstreams eliminate resource contentions, selectively eliminate asynchronous behavior, include built-in test circuits, and are relocatable. Multiple populations of configuration bitstreams can evolve in parallel over a network.
