Abstract: The present disclosure relates to a computer-implemented method for automated generation of ASIC design files for machine learning workloads. A computing system receives a representation of one or more machine learning models, along with an initial configuration of configurable hardware elements and an initial mapping of workloads associated with model execution.

Simulation and update operations are iteratively performed until a termination condition is satisfied, producing progressively improved configurations or mappings. Upon completion, one or more ASIC design files are generated based on the final configuration and/or mapping.
