Easy to use and very helpful

I’m using this app while studying The Elements of Computing Systems from O’Reilly. I tried a few other apps, but this one has been the least frustrating to use.

I’ve only been using it for a short time, but I really like it so far. I hope the developer keeps improving it!

FAQ

What is Logic Circuits Simulator?

Logic Circuits Simulator is a digital design tool for building and simulating logic circuits. It includes standard gates, sequential logic, Karnaugh maps, and features schematic-quality wire routing. The app is designed for educational purposes, particularly for students studying digital design.

What kind of logic gates are available in Logic Circuits Simulator?

Logic Circuits Simulator supports a full set of IEEE-standard gates including AND, OR, NOT, NAND, NOR, XOR, and XNOR. Gates can be scaled from 2 to 8 inputs, and constants like Ground and VCC are available for clean schematic structure.

Can I simulate sequential logic with Logic Circuits Simulator?

Yes, you can build and simulate sequential logic components such as counters, registers, and state machines. The app provides an adjustable-speed clock with pause and single-pulse control, along with D, T, JK flip-flops, and SR latches.

How does Logic Circuits Simulator handle circuit visualization?

The app features schematic-quality wire routing that automatically creates orthogonal paths with rounded corners, hop bridges over crossings, and junction dots. This ensures your circuits look like professional textbook diagrams rather than tangled messes.

Does Logic Circuits Simulator offer Karnaugh map functionality?

Yes, Logic Circuits Simulator can flip any truth table into a Gray-coded Karnaugh map for 2-4 variables. It visually highlights covering groups in color and generates the minimized sum-of-products expression using the Quine-McCluskey algorithm.

Can I create and reuse custom circuits in Logic Circuits Simulator?

Absolutely. You can package any combinational circuit as a custom integrated circuit (IC) with named pins. These custom chips can then be stamped into larger designs, and your chip library syncs across devices via iCloud.

How can I share my work created with Logic Circuits Simulator?

You can export circuits as .lcs files to share via email or messaging apps, with embedded chips included. Additionally, you can export PNG snapshots of your circuits and CSV truth tables for reports.

Does Logic Circuits Simulator have ads?

No, Logic Circuits Simulator is ad-free. The developer explicitly states that the app is always ad-free, with no in-app purchases or subscriptions.
