All Versions of LoCAD

7.6

February 9, 2024

This update fixes a display error in the IC interior view. Due to a programming error when hiding dummy leads (see version 7.0), some short leads that lead to component connections are not displayed in the internal view of ICs. As this is only a display problem, it has no effect on the function of the ICs.
More

7.5

February 2, 2024

This update fixes a display error in the LED matrix and contains further stability improvements.
More

7.4

November 6, 2023

This update • contains stability improvement • adds a diode to the basic elements and an LED matrix and an enlarged seven-segment display with integrated decoder to the block elements. This ensures the exchange of circuits between the macOS and iOS versions.
More

7.2

September 13, 2023

This update contains some improvements for editing cutouts.

7.1

August 30, 2023

This update • improves the algorithm for automatic dragging of lines in connection with the basic element location options added in version 7.0. • eliminates the short line pieces for creating gaps (see version 7.0) from the IC internal circuit
More

7.0

August 14, 2023

This update contains the following changes: • By popular request, the position options of the basic elements have been added, so that the outputs can now also be directed to the left and upwards. The desired position can be selected via the arrows in the second row. • When creating ICs, input lines without a connection to a component that are a maximum of 3 grid units long are not drawn as a connection at the IC edge but are entered as a gap in the row of connections.
More

6.4

July 29, 2023

This update • fixes a problem that occurs when deleting nested ICs • now also considers the possibly existing negation points at IC inputs when
 initializing a circuit • shows the exact delay value in the signal delay window.
More

6.3

July 22, 2023

This update • prevents the possible wrong positioning of ICs with a very short click on the touchpad • fixes a bug when using negation points at IC outputs.
More

6.2

July 9, 2023

This update removes a minor ambiguity regarding connection designations when creating ICs.
More

6.1

February 7, 2023

This update fixes a bug regarding the language setting.

Price History of LoCAD

Description of LoCAD

LoCAD is a software for designing and simulating digital circuits. Special emphasis is given to simple creation and graphical visualization of a circuit's functioning. The inputs and outputs of the elements can be wired quite simply. Usually, two touches are sufficient. The system searches a convenient way by itself. In the simulation, you can watch the current flow and thus follow the cycle of state changes. This way, your understanding of a circuit's functioning is enhanced, and your perception of circuit faults is improved. It is possible to produce your own elements (ICs) with discretionary levels of nesting. Like this, you can build big and complex circuits in a clearly arranged way. During the simulation, you can watch the state changes in all ICs. A detailed introduction facilitates your familiarisation with the software.

Reviews of LoCAD

  • Excellent

    I am a retired physician and an electronics hobbyist. I came upon LoCAD after some success and excitement with electronic simulation programs like icircuit. I was surprised that LoCAD was not really reviewed! At first I thought that it was simply a simulator, like iCircuit. But I discovered that it was also an entire educational course that teaches Boolean electronic concepts.

    LoCAD is a simulator available for the Mac or iPad (apparently, it also works on Vision Pro!) in combination with two iBooks on electronic logic and microprocessors. With the LoCAD program you can teach yourself how a microprocessor works FROM THE TRANSISTOR LEVEL UP. The books show how basic digital Boolean gates are made. With the Boolean gates and their combinations (provided), you can make your own complex integrated circuits. Using the books and the program together will allow you to make a simple microprocessor with its own assembly language in short order.

    LoCAD LV is the free MacOS version. A maximum of 9 components can be used with this version. The LV version can be upgraded to a full version. The LoCAD SV version is the MacOS school version, which already contains the activation for the full version to enable distribution via the Apple School Manager.

    LoCAD and LoCAD Lite are the iOS versions that run on iPad and via Mac Catalyst on Macs. LoCAD is the full version, and in the free Lite version a maximum of 13 components can be used.

    My advice is to purchase the LoCad full version and the two iBooks when you start.

    I think people are downloading this program and not purchasing the inexpensive, well-written books which make the programming SO MUCH more understandable, unless perhaps you are already an EE chip designer. The LoCAD interface does not always adhere to the Mac interface (zooming, moving on the work area, right click menus for example), so there is a bit of a learning curve with the program interface.

    The iBooks on the Mac did not allow text size adjustments, perhaps because that would interfere with the interactive examples. I have not yet explored the same parts of the iBook and program on the iPad. Overall it really is an amazing introduction to electronic logic and its application. If you want to try it, purchase the two iBooks along with LoCad. With a little effort you won't be disappointed.

    Thank you Karl for the education!

  • Great app but a problem

    I love this app! I can’t toggle the switches when the clock pulse generator is running.
