Method for programming a field programmable gate array and network configuration
A method for programming a Field Programmable Gate Array (FPGA) via a network, the network being operated according to a predetermined communications protocol, can include: establishing a communication connection between the FPGA and an external master, setting the FPGA into a programming mode, the master providing an FPGA programming image to the FPGA in a sequence of frames so that the frames can be parsed and enabling the FPGA to write only during receiving the payload section of the frames. The FPGA programming image and parsing the sequence of frames can be performed by a permanently programmed or hardwired logic component. A network, FPGA, and a communication system can be configured to utilize embodiments of the method.
MULTIPLE PARTITIONS IN A DATA PROCESSING ARRAY
An apparatus includes a data processing array having a plurality of array tiles. Each array tile can include a random-access memory (RAM) having a local memory interface accessible by circuitry within the array tile and an adjacent memory interface accessible by circuitry disposed within an adjacent array tile. Each adjacent memory interface of each array tile can include isolation logic that is programmable to allow the circuitry disposed within the adjacent array tile to access the RAM or prevent the circuitry disposed within the adjacent array tile from accessing the RAM. The data processing array can be subdivided into a plurality of partitions wherein the isolation logic of the adjacent memory interfaces is programmed to prevent array tiles from accessing RAMs across a boundary between the plurality of partitions.

Hybrid synchronous and asynchronous control for scan-based testing
An integrated circuit includes an intellectual property core, scan data pipeline circuitry configured to convey scan data to the intellectual property core, and scan control pipeline circuitry configured to convey one or more scan control signals to the intellectual property core. The integrated circuit also includes a wave shaping circuit configured to detect a trigger event on the one or more scan control signals and, in response to detecting the trigger event, suppress a scan clock to the intellectual property core for a selected number of clock cycles.

Techniques for reducing uneven aging in integrated circuits
A programmable integrated circuit includes configuration circuitry configured to receive configurations of a user design for the programmable integrated circuit. Each of the configurations implements the user design using at least some unique circuitry in the programmable integrated circuit relative to the other ones of the configurations.
