ello there!
I'm new to FPGAs but I'm wondering how one would treat this problem.
There are two buttons as input and each one has a corresponding output say SWA/SWB and LEDA/LEDB.
Basically if SWA is pushed, LEDA should be 'latched' until the system is reset. Same for SWB which would latch LEDB.
Now here's the tricky bit - if both are pushed simultaneoulsy then we 'toggle' between LEDA and LEDB for each successive simultaneous pushes.
Does one treat this like an F.S.M. problem, with Mealy model? I tried doing a state table/state diagram and hit a brick wall with the latching part.
I have come up with a design that involves simple logic but I'm wondering if there is a much better way of doing this. The way I set about it is how a caveman would - no proper planning and thinking how this would work...
So any help in solving this to give:
state diag
state table
expanded state table
minimization
final system diag
Thanks a lot!
