Yes i use splitter now for 8bit+ components, it is very helpfull to clarify design. thks again.

Effectively, there is not 0 default value for pin not connected, i think program try to get a value with hasardous memory location because object on pin does not exist. We must connect them to à constant value. May it be an interresting evolution to program to take a default value 0 when a pin is no...

ok, there it is.

hi again, i am trying to experiment substration between two 8bit binary numbers. 1 bit adder is working perfectly. when i chain it to 8bit adders, some error where done: this is my adder 1 bit, and the 8bit adder: adder.png This is the main board to substract B to A: adder2.png Woaaah!! 0-0=3 a Quan...

ugh! i hope i dont need clocks... i already tryed it, but it is not not working yet. too newbie i think.
thanks anyway.

hi,

first thanks for this soft! it was a very helpfull laboratory for me.
I have a problem to simulate this specific circuit:
Just wanting to make a flipflop button.
error when pushing button in left : oscillations!

any idear ?
