hello,
i’m currently working on project #4 and i have two questions:
-
in the multiplication circuit, are we supposed to use a tree of only 4:2 adders and a single csa? or can we use any amount of 4:2 and csas?
-
i’ve been experiencing some technical difficulties with logisim for a while now, but it’s gotten really bad in the past few days - it started with just multicoloured wires, but now
circuits that worked completely fine are suddenly not working anymore (with certain outputs randomly marked with X instead of 0 or 1), and then miraculously coming back to life. it’s also been working increasingly slowly, to the point of freezing every time i try to work on the project.
i’ve tried resetting the simulation and a few other things but nothing i do seems to directly fix the issue.
have i possibly done something wrong with one of the circuits or is this a bug with logisim? how can i fix this ?
thank you
