Idea

The idea for this program came to mind shortly after I made my little alu representation. I was building a little ripple carry adder in the popular sandbox game Minecraft when I suddenly got the idea for this program.

Use cases

This program can be used to understand how logic gates work, visualize complex structures or just play around with different gates.

Controls

• Hold left click to drag nodes / draw connections
• Right click to remove a node
• Hold middle click to move the whole screen

Available gates

• AND, OR, XOR, NOT (Inverter)
• Splitter (Takes a signal and outputs the same signal twice)
• BCD to 7-segment display gate

The following are not really gates, but I don't know where else I could list them:

• Input (Can be altered by the user; Double click to toggle the state)
• BCD Input (Converts a decimal into a binary-coded decimal)
• Output
• 7-Segment display output

Known bugs

• StackOverflowError when creating infinite recursion (#1)

Todo

• Finish javadoc comments (#2)
• Add Json exporter and importer (#3)
• Add a tool to create custom gates from Json exports (#4)
• Maybe add more gates?
