Four-Bit Bus Multiplexer
Every datapath is full of forks: two 4-bit values arrive, one control bit decides which continues. Doing this with four scalar 2:1 muxes works, but the bus multiplexer says what you mean — one component, one select, whole operands.
Build a circuit that routes one of two 4-bit buses to the output:
Y = SEL ? B : A
When SEL = 0 the output follows A; when SEL = 1 it follows B.
Constraints
- Use the Bus MUX 2:1 component from the Buses palette group.
A,B, andYare pre-placed at 4-bit width — connect them as buses.

Solve this problem
Place the gates, wire them up and watch the signals settle. Every submission runs on the same simulation engine that grades it.
