Most of the FPGAs have 7-segment decoders. These 7-seg displays are of following type:
When I started working with VHDL and FPGAs, the first ever project that came to my mind was blinking an LED. But since we all know that most of the development boards have high frequency clocks from around 20MHz to as high you can get. So if we directly connect that clock to LED the blink rate will be so high that it will not be visible to our naked eye.
