Could you describe your design and how you are attempting to solve the problem?

Nevermind, I got it working. I have to display the digits on a 7 segment display, I am thinking of using binary to bcd, but how do I start on it? Do I make a state table first?

Binary to BCD can be done combinatorially.

But that can require a lot of logic.
Here's a discussion on other approaches for binary to BCD.

Hi,

How many digits do you have to show?
If it is a small amount then logic works ok, but if you need like 6 digits probably do it in code. There's an algorithm on the web called something like "double dabble" which i have used several times and it doesnt take up a huge amount of memory space.
Example:
