Example embodiments of the present disclosure provide methods and devices for optimizing performance of hardware accelerators. The accelerator device may detect status information of a current acceleration task being executed. The detected status information is provided to a host associated with the accelerator device. The host makes preparation for a subsequent acceleration task based on the status information before termination of the current running acceleration task. The accelerator device may execute the subsequent acceleration task based on the preparation. In this way, the performance of hardware accelerator is optimized.

Performance optimization of hardware accelerators

A computer program product for calculating a path delay in static timing analysis (STA) for a circuit design includes determining a connectivity between a first device and a second device in a path of the circuit design, generating a delay constraint associated with the first device and the second device based on the connectivity, the delay constraint specifying a correlation between a first device delay of the first device and a second device delay of the second device, and calculating a path delay of the path based on the first device delay and the second device delay that satisfies the delay constraint.
