Basic, over-minimalistic logic gate simulator. RIS Gates Page.
Warning: The evaluation aspect of this project may display flashing lights.
It uses a grid to place four types of tiles:
- IO (Input/Output): Allows you to toggle its state in evaluation mode.
- Negate (2 NOT gates): Inverts the input. One gate is horizontal, the other is vertical. This allows you to cross over two lines by connecting three negates.
- Conjoin (3-way OR Gate): Outputs towards the direction it is facing and takes input from every other direction.
- Disjoin (3-way split): Takes input from the direction it is facing and outputs every other direction.
Negate and IO do not output or take input themselves. Rather, a Conjoin or Disjoin which is connected to them will.
In evaluation mode, you can either toggle IO states or step through the changes in every tick. A tick consists of first updating all non-Negate tiles, and then updating the input of Negate tiles. Therefore, updates in logic gates using Negates may take more than one tick to propagate. Because of that, there is also the option to skip to the next stable tick. A stable tick is any tick where no updates happen. Note that if a logic gate has any cycles will not allow for a stable tick to happen.
