Abstract

A circuit arrangement for supplying configuration data in an FPGA device includes a plurality of output flip flops allocated to respective configurable logic cells of the FGPGA device. Each output flip flop comprises at least one data input and one data output and a data input of a first output flip flop of the plurality of output flip flops is switchably connected to a data output of a second output flip flop of the plurality of output flip flops for forming a shift register by means of a switching device integrated in the FPGA device.
