Welcome to the latest update of Logic.ly — the educational logic gate simulator with an intuitive drag-and-drop user interface that lets you learn all about boolean logic and computers.
This update introduces a new option to disable strict mode in a document. Traditionally, most of the components in Logic.ly would treat High Impedance (Hi-Z) values the same as errors. Only the Pull Up, Pull Down, and Bus components would accept Hi-Z values. Now, when you disable strict mode, Hi-Z values will be ignored by logic gates instead. It will be as if the gate had one fewer input connection.
In practice, this makes it a bit easier to create multivibrators and other “unstable” circuits. However, it potentially comes at the cost of performance, meaning that the simulation could use a lot more CPU cycles when it gets into an unstable state, like an “infinite loop” in programming.
This update also introduces a way to edit the name and label of a custom integrated circuit. In the components picker, you can now right-click and choose Edit Properties…. This will open a dialog that allows you to edit some of the IC’s properties:
The Limit Signal Propagation Time setting has also received a revamp. Previously, you could limit the propagation time to the rendering frame rate, or it could be unlimited.
Now, there are a few longer fractions of a second available to slow down the simulation even more. These make it easier to watch propagation changes with the simulation running.
