redstone.hdl

A random HDL brainstorm for Minecraft redstone.

module ComparatorClock(delay_ticks) {
    default input toggle: 1
    default output out: 1
    component comp: Comparator(mode: "subtract")
    wiring {
        toggle -- comp
        comp -- Repeater(delay: delay_ticks) -- comp.side
        comp -- out
    }
}

braces
a module is the basic component
modules have inputs, outputs, and parameters
inputs and outputs are for redstone, parameters are for config
inputs and outputs defined by their respective keyword
inputs and outputs have a width, like in verilog. here both 1
subcomponents use the function-call-like syntax
wiring defines the implemenation
-- is a redstone connection
Repeater(delay: delay_ticks) is a repeater subcomponent, with the delay set to the delay_ticks module parameter
module parameters passed by name
component is basically a variable for subcomponents
Repeater(delay: delay_ticks) -- comp.side wires a repeater to the side input of the comp (which is a Comparator)
default allows you to wire inputs/outputs without specifying them explicitly
here, the comparator has a default input, a side input, and a default output
