Combinational Feedback Loop
A handshake controller asserts a ready signal based on the incoming valid and enable control signals.
Expected behavior:
| valid | enable | ready | |---------|----------|---------| | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 1 |
Simulation shows ready = 0 for input valid = 1, enable = 1. The synthesis logs also report a combinational loop warning on the ready net. Inspect the circuit and correct the fault.
Constraints
- Only rewire the existing gates to fix the logic path.
- Do not add flip-flops or clocks to the circuit.
Topics
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.
