Fdce xilinx

I would like to know the altera quartus primitive equivalent to the FDCE flip flop on Xilinx ISE. I think that DFFE primitive might work however I am not sure about the CE and CLR pins equivalency. Also the PRN pin confuse me. I have included a link to the altera documentation that I have been using so far.

D, Eingang. Q, Ausgang. CE FDCE is a single D-type flip-flop with clock enable and asynchronous clear. When clock enable (CE) is High and asynchronous clear (CLR) is Low, the data on www.xilinx.com. 501. ISE 6.li. 1-800-255-7778 Q <= D; end if; end if; end process; end Behavioral;.

You may use schematic methods and the FDCE flip-flop component Devices in the Xilinx 7 series architecture contain eight registers per slice, and as a preset or clear port (represented by the FDCE or FDPE flip-flop primitive). 2019年4月30日充分利用Xilinx®器件的架构特性。 1 Flip-Flops and Registers ： Vivado综合根据 HDL代码的编写方式推断出四种类型的寄存器原语： •FDCE However, for a more detailed description of each Xilinx Constraint, you can refer to the Constraints Guide Figure 8: INIT and IOB constraints of FDCE flip-flop.

synth_xilinx - synthesis for Xilinx FPGAs synth_xilinx [options] This command runs synthesis for Xilinx FPGAs. This command does not operate on partly selected designs. At the moment this command creates netlists that are compatible with 7-Series Xilinx devices.

INIT defines the initialization value of the flip-flop after powering on the FPGA. Re-coded Xilinx primitives for Verilator use. Contribute to fredrequin/verilator_xilinx development by creating an account on GitHub.

This functionality can’t be utilized by any other logic when you are using it for the shift register. Thus, the additional enable input won’t consume extra resources.
