An integrated circuit comprising a field programmable gate array including a plurality of logic tiles, wherein, during operation, each logic tile is configurable to connect with at least one other logic tile, and wherein each logic tile includes: (1) a normal operating mode and test mode, (2) an interconnect network including a plurality of multiplexers, wherein during operation, the interconnect network of each logic tile is configurable to connect with the interconnect network of at least one other logic tile in the normal operating mode and (3) bitcells to store data. The FPGA also includes control circuitry, electrically connected to each logic tile, to configure each logic tile in a test mode and enable concurrently writing configuration test data into each logic tile of the plurality of logic tiles when the FPGA is in the test mode.
