Hi,
Thank you for sharing your thoughts and ideas. Adding comments to circuit is on radar for the next version.
Can you please explain what kind of hints did you get and how did you find them?
Thanks,
Eugene

Hi Peter,
Thank you for your suggestion. This feature is high priority for the next version.
In the meantime the tooltip is shown when you hovering your mouse over the pin.
Thanks,

Sorry, this extension was not allowed. I’ve enabled it. Can you please try again?

Thank you for your wonderful contribution. Can you also upload the project file itself so people will just need to copy/paste what they want?

Hi Bill, There are could be either a bug in the program or you did not actually connected wire to pin. Please do the following: click the wire that is not working properly and see if it ends at the right places. If it is drawn correctly, then please save this file and send to me. You can attach it h...

Hi Bill,
You can upload your circuit right here or create a new topic.
Thanks,
Eugene

Hi, Your JK is level controlled flip-flop which usually make it really hard to get in sync. If you want to simulate the actual schematics of 4000 series and you are sure it uses such flip-flops, than we probably need to figure out their design. If you care about logical side only then there is a JK ...

There are no delays per se, but gates get evaluated in same way as real signal will be spread. That means that if you need to have your signal delayed you can add two inverters and they do the trick. However this technic is not reliable both in the program itself as well as in the real life circuit....

Thank you for your suggestions. Labels on the body of circuit’s symbol is really good idea and it will definitely deserve some time spent implementing this feature. So you can expect it in one of the next versions. Meanwhile there is a tool tips shown when you hover your mouse over the input/output ...

Hi Soc, You don’t have flip-flops on the palette because there are only either primitive gates there or circuits you’ve created. So just create a new circuit call it D flip-flop and it will be on your palette. You can reuse any circuit from other project as well, just open this project in another in...
