This sounds consistent with the guidance in Xilinx WP272 (Get Smart About Reset...). Why then, do the 7-series/Zynq devices have a FDCE primitive? Granted, this question assumes that the term 'set' and 'preset' are synonymous, as are the terms 'clear' and 'reset'. Jul 30, 2018 · FDRE D-type flip-flop of the Xilinx 7 series FPGAs. Image courtesy of Xilinx.
