if you just insert clock only in add3:

always @ (posedge clock)

I tried using CLOCK_50 which I think should work on my DE1? And the display just read 0

Check with pencil and paper! Perhaps you can give a numerical example of what you want to achieve.

Thats what is driving me absolutely crazy. I have done it hundreds of times on pen and paper and it's work.

I'm trying to convert binary like 01011 to 0001 0001.

Here's a run through.

TENS|ONES|01011

0000|0010|11 SHIFT 3 (no +3)

0000|0101|1 SHIFT 4 (ones is >4 so +3)

0000|1000|1

0001|0001| SHIFT 5

And the 5th shift gives you the BCD!
