ABSTRACT:
Various approaches for indicating completion of configuration of programmable logic devices are disclosed. In one embodiment, a plurality of configuration memory cells are arranged for storage of a configuration bitstream for implementing a circuit design on the programmable logic circuit. A plurality of configurable resources are coupled to the configuration memory cells, and each configurable resource implements a function based on data stored in one or more of the configuration memory cells coupled to the configurable resource. A logic circuit is coupled to a subset of the configuration memory cells and is configured to assert a done signal in response to states of the subset of the configuration memory cells.
