Abstract:
1. A method of configuring a programmable integrated circuit, comprising: receiving a configuration stream having first data for programming first locations in a configuration memory and an instruction for referencing circuitry in the programmable integrated circuit; obtaining second data from the circuitry based on the instruction, the second data including device-specific data configured to compensate for at least one of process characteristics or environmental characteristics of the programmable integrated circuit; and programming second locations in the configuration memory with the second data to adjust attributes of at least one tile in a fabric of the programmable integrated circuit; wherein the first locations and the second locations comprise a frame of the programmable integrated circuit, wherein the first data programs the frame, and wherein the instruction modifies a portion of the frame by causing the second locations to be programmed in response to the second data.
