Since you support a Buffer gate with tri-state outputs (0, 1 and open), it would be useful to use a different color wire when it’s output is open. Currently it uses dark green (the same as a 0 output) when the buffer’s output is open. In the case where the outputs of multiple buffers are tied together, the wire path would be light or dark green to reflect the output of the enabled buffer, o...

The default Flip Flop is positive edge triggered, but I need a negative edge triggered flip flop. How can I implement that?

I'm trying to find a way to update the circuit elements in the simulation canvas via the developer console. The reason for this is that I'm constructing a circuit where each stage has multiple elements with individual delays. These cumulative delays will affect the output of the circuit. I started by inspecting the HTML and Javascript for the simulation canvas. The UI elements and images are...

https://circuitverse.org/users/49622/projects/subcircuit-problem I created a minimum circuit that demonstrates a problem I saw in a larger circuit. In this circuit, there's an input with a tristate gate attached to a common bus. Also on the bus is a D flip flop, with it's input from the bus, and it's output sent to a tristate gate which outputs to the bus. That's the upper circuit on the Mai...

I'm reading the book called CODE by Charles Petzold. I'm currently in page 159 and I built a 8 bit binary adding machine that has 2 8 bit inputs. The sum is saved in an 8 bit level triggered D-type latch and the output of that 8 bit latch is given to the 2nd 8 bit input of the 8 bit adder. There's an Add button in the 8 bit latch which is basically just the clock, when 0 it will not save the 8 ...

I wanna put capacitors in my circuit, but i don't see them in the circuit elements. If you can't add them, please tell me an alternative to them that i can use in my circuits.

I am making a booth algorithm multiplicator, which is due today. The project was close to finish, but out of the absolut blue, the page froze and I have not being able to use it again ever since. It happens only on this specific circuit, it loads forever, I can't interact with anything, can't copy. please help

Hi all, I couldn't find a full explanation of the delay setting on the documentation. Would someone please explain this setting in some detail? We need to have a delay to build our own edge-triggered D Flip Flop, for example, but the setting isn't working as expected. Also, how could we build a SR latch using just gates that saves in a certain state or the other, rather than randomly choosing i...
