Joiner
Joiner: combines n single-bit wires into one n-bit bus.
Pins
b(n−1)…b0 on the left, highest bit at the top; one n-bit output on the right.
How to use it
Assemble switch or gate outputs into a number for a value display, a register or a RAM address.
Usage example
The opposite of a splitter: combines four single-bit signals into one bus. b3–b0 = 1011, shown as 0xB (that's 11).
Common mistakes
The joiner's width must match the bus pin it feeds: 8 bits for a RAM's Din, the RAM's address width for A.
