VLSI Craft is a hardware generation toolchain for Minecraft inspired by VLSI CAD: Logic to Layout course. It allows you to translate simple Verilog programs into Minecraft logic gates and wires.

• Combinational logic mapping
• Simple 2D placing
• Multilevel routing with conflicts resolving
• G-code generation

All other things like milti-level logic optimization and technology mapping are done by yosys and abc.

• yosys (tested with version 0.5)
• ComputerCraft mod v1.6 or later with HTTP API enabled
• redlogic mod (tested on 57.2.1)
• Qt (tested on 5.4.0)

• Compile yosys and place binaries into tools directory
• Compile all other tools from this project and place them into tools directory
• Go to examples/full_adder directory
• Adjust *_job.xml files according to your world coordinates
• Run make
• You will get result.gcode file, transfer it to the Pastebin
• Load Minecraft, place wireless turle on the origin point
• Place PC+wireless modem somewhere
• Load chests with items
• Cleanup working area
• Load GTurtle client and server software (found in the gturtle directory) into the turtle and pc, respectively
• Run client software
• Connect to the turtle with server software

• Gates can be rotated incorrectly
• Turtle can overflow and behave wrong if the number of items in chest is not a multiple of 16 (ComputerCraft bug).

• Routing without "ladders".
• Sequential logic is not supported for now (but can be easily added)
• 3D gate placer
• Fast placement by turtle without useless rotations
• Support for massive fan-out networks
