よくある質問

よくある質問

What is a logic gate diagram and when do I need one?

A logic gate diagram shows how Boolean logic is implemented in hardware — inputs flow through gates (AND, OR, NOT, etc.) to produce outputs. You need one when designing digital circuits, explaining combinational or sequential logic, or documenting a safety interlock or control system.

Which gate types does the diagram support?

The generator supports all standard combinational gates (AND, OR, NOT, NAND, NOR, XOR, XNOR, BUF), output buffers (TRISTATE_BUF, OPEN_DRAIN, SCHMITT), flip-flops (DFF, JKFF, SRFF, TFF), latches (LATCH_SR, LATCH_D), and complex blocks like MUX, DEMUX, DECODER, and COUNTER.

Can I customize the diagram after it's generated?

Yes. Describe the change in the chat — for example, "add an active-low enable input" or "group the output stage into a separate module" — and the AI updates the circuit and its labels in seconds.

Can I export the diagram?

Yes. Export as PNG from the editor toolbar, or copy the diagram to paste into lab reports, design documents, presentations, or datasheets.

Is it free to use?

With a free account, you can create diagrams for free. No credit card is needed. You can save your circuits and generate diagrams.
