BrianHG:
Use a different proper reset line which I have made available throughout your project.

BrianHG:
Well?

nockieboy:
No progress this week, I'm afraid.  I haven't had any time to even think about the project, let alone work on it.  The last thing I tried was a fixed reset line, no change.  Maybe I'll have some time at the weekend. :-//

nockieboy:
Have just tried with fixed reset, both high and low just in case it was active high, still getting zero from the FPU.  I'm setting A and B inputs to 7 and 9 respectively, I'm able to read the results back, and the Q output isn't changing at all - all I'm reading back is 0's.

Latest project attached so we're on the same page.

BrianHG:
Place in an absurd number.

Remember, it is floating point, the exponent needs to be set, though anything you enter besides 0 should work.

It may be a bug in the megafunction.

Can you try an integer 32x32bit multiply?
