Hi, Thanks for your suggestions. Can you please explain what do you mean by programmable input? There are buttons you can use and if you need Z value you can build your own circuit that will do the trick. Please see Displays in help for more details. What do you mean by clock cycle? And what is the ...

Hi Hans,
I guess you can’t disable comments on the topic on this forum software. But you still can upload multiple files in one or many topics and even if people will comment on them you might be find it valuable.

Hi Markus,
Thank you for your support and suggestion.
In latest version you can just click and hold mouse button to see the state of wire when the power is on.
I hope this will help your kids.
Thank you,
Eugene

Dave,

Yes, you are right the notation of the pin is truncated to 2 characters if it resides on the left or right sides and to 4 for top and bottom. The reason for this is small amount of space for the text on the symbol. You can use not only letters and digits there though. For example for the clock input...

Hi Hans, Thank you for sharing our thoughts. The way the program simulates the circuit is a bit more complicated than you’ve described. So first of all the drawings are translated to set of objects that can perform logical operations – gate functions. During this translation all the connections are ...

Thanks for sharing your project.
Can you please provide a bit more details on what it is doing and how it works - some sort of big picture overview?

Yes you are right the memory block has mechanism very similar to D latch. Namely it writing its data when write signal is changing. But you have more than one memory blocks chained together. So it is possible that two will be flipping their state in the same clock cycle. So having two inverters make...

In your very last circuit where AND gate does not have any inputs connected the entire circuit get optimized away. Now back to your original problem. I think you are trying to solve incorrectly defined problem. Instead try to think about your circuit as a bus with multiple data providers each of the...

Yes, I know about this effect. The root cause is in how Windows works. It has a way to schedule timer with resolution of 1 millisecond, but actually it can’t run more frequently than every 30ms or so. I was thinking how to solve this and I can reduce the range of the frequency slider to 30 instead o...
