Xilinx FDCE flip-flop primitive. Most FPGA architectures have flip-flops with an optional enable (E) or clock enable (CE) input. 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.

Can't vivado just infer which signal is the clock based on which ever signal is going to "posedge" or "rising_edge" statement? Vivado knows what all the clocks are (after all it gives you a warning on your clock pin), but it does not know the parameters of that clock: frequency, duty cycle etc.

The GUI of the editor simplifies entering the constraints by guiding you through the constraint creation without having to understand the UCF syntax.

A counter is a device which stores the number of times a particular event or process has occurred, often in relationship to a clock signal. There are two types of counters: ☞up counters ☞down counters. Up counters In 2018, Xilinx announced a product line called Versal. Versal chips will contain CPU, GPU, DSP, and FPGA components.

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.
