HI, I am doing an ASM for a fibonacci sequence, but I am getting this error from logisim. Can someone help me fix this, I have been trying to for hours already but no success.

 

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.

 

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.

 

Can You please describe where the start, reset, stop point going? Which circuit is it?

hey, can you explain me how you did the circuit? or send me what you did? that will help alot

 

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:
0000 0000 1111 start with 0,0,15
0000 0111 1000 shift left 3 times
0000 0011 1000 add 3 to center group
0000 1010 1000 result
0001 0101 0000 shift left 1 time, result is 1,5,0 which is read "15" in bcd.
There is a little more to it so you'll have to read up on it.
