What is the purpose of the UCF file?

UCF is a special file format you can use to display rich media files in WebEx sessions, as well as share any type of document, including PowerPoint and Excel files. UCF files can contain the following types of rich media content: WebEx WRF recordings (for more information about WRF files, see Recording and Playback.

How do I create a UCF file?

You can do it from the ISE -> User Constraints -> Generate Timing Constraints. That will open a GUI that will help you generate the UCF.

What does UCF mean in a VHDL file?

The UCF file usually (I have never seen done it in other ways) refers to signals in your top file. In this top file, then, you can instantiate other VHDL files that are in your project. As for the clock divider, in many applications you need to get lower clocks (e.g. you need to interface with a slower external device).

How are flip flops used in a clock divider?

A flip-flop is an edge-triggered memory circuit. In this project, we will implement a flip-flop behaviorally using Verilog®, and use a bunch of flip-flops to implement a clock divider that blinks the LEDs. Before you begin, you should:

When to use a clock divider in VHDL?

You can use the system clock if it meets your needs. Very often, real designs require clocks at a specific (lower) frequency, or multiple clocks at different frequencies, which is where clock dividers would be used. A gentle dead tree introduction to VHDL programming for Xilinx I can recommend is this book.
