The FDCE is an asynchronously cleared, enabled D-type flip-flop. When clock enable (CE) is high, the output Q takes the value D, on a rising clock edge. If at any time the CLR signal is asserted, Q is forced low. (Source: XACT Libraries Guide, pg. 3-248, Xilinx Corporation, 1994.)

I am able to use these default modules in xilinx schematic like M2_1 MUX, FD flipflop etc.. In verilog I can able to use only elementary gates like and, or ,not,xor etc.. But can I use these built-in Multiplexer (M2_1) or Flipflop(FD) in verilog?, because if I use behavioral code, there may be poor synthesis in synopsis or xilinx for some cases.
