VERILOG
LAB HUB

Every gate, adder, subtractor and mux from the lab — with a live truth-table simulator baked into each card so you can flip bits and watch the logic think before you even open ModelSim.

Basic Logic Gates

The OG boolean besties. Toggle the inputs on each card and watch the LED do its thing.

➕combinational · arithmetic

Adders

Bits that carry the group. Half adder, full adder, and a structural build made from two half adders.

➖combinational · arithmetic

Subtractors

When bits gotta borrow from a neighbor. Half and full subtractor, borrow-out included.

🧮combinational · 4-bit

4-Bit Adders

Four full adders, ripple-carry chained. Toggle all 9 input bits and watch the sum roll over.

🔀combinational · routing

Multiplexer & Demultiplexer

Pick a lane, or split the signal. 2x1 up to 8x1 muxes, a structural build, and both demux sizes.

// no modules match that query — try "mux", "adder", "xor"...
