Welcome to your first circuit. A “circuit” here is nothing more than a piece of wire: whatever value appears on the input should appear on the output, at every instant, with no delay and no logic in between.
This introduces the basic shape every problem on this site will use: a module (or entity) with a fixed set of ports that you must implement to match the given interface exactly.
Interface
| Signal | Direction | Width | Description |
|---|---|---|---|
in |
input | 1 | The value to be copied |
out |
output | 1 | Must always equal in |
Notes
- Use a single continuous assignment (
assignin Verilog/SystemVerilog, a concurrent signal assignment in VHDL). No clock is involved — this is a purely combinational circuit. - The VHDL port names are
in_bit/out_bitbecauseinandoutare reserved keywords in VHDL and cannot be used as identifiers.
