Abstract
Systems and methods are disclosed herein to provide an improved approach to the configuration of integrated circuits such as programmable logic devices (PLDs). In one example, a method of operating a PLD includes receiving a configuration data bitstream at a slave serial peripheral interface (SPI) port of a PLD from a master SPI port of a first external device. The method also includes passing the configuration data bitstream through the PLD from the slave SPI port of the PLD to a master SPI port of the PLD. The method further includes providing the configuration data bitstream from the master SPI port of the PLD to a slave SPI port of a second external device.
