Yes there is a zoom slider under the main diagram panel. Just hoover your mouse over the narrow horizontal rectangle at the bottom and it will slide up and you’ll see a number of controls to adjust zoom and frequency of clock gates.

This version does not have text yet, but the next one will let you put a text block on the diagram. What you can do right now is to group some set of circuits and make another logical circuit out of them. This circuit will have a name, notation and description. The latest will be visible when you ho...

Hi, This software emulates logical circuits, so there is no power or ground per se. But there are some elements that can produce logical 0 or logical 1. The button is one of such elements. Its output pin produces value 0 when the button is depressed and 1 when it is pressed. Another example would be...

Hi Skyaxe, The circuit has one problem. The wire in the left upper corner is not connected to any connection point but rather just floating and only touching the side of the NAND gate. It is fairly simple to detect such kind mistakes. You need to power off the circuit and click menu Edit/Select Free...

I don’t have such circuit at the moment. The closest you can get is counters and comparers in digital clock sample on download page.

It is comming in the next version

You probably can have another counter and count clock cycles till it 1.5 sec passed. You can do it knowing your work frequency. Once you’ve counted enough, you’ll stop counter and raise signal allowing reverse operation of your car.

You can change the shape of the gates in the Options. Just click menu Tools/Options.

It is User Control Panel link on top-left corner on the forum's page.

You need to bundle 4 bits of your counter with splitter. Then you can connect splitter to the ROM’s address. Please see Splitter section of help at: http://www.logiccircuit.org/splitter.html
