Multiple Driver Conflict
A status generation circuit asserts an alarm flag when both primary sensors detect an event and the manual override is disabled.
Expected behavior:
| A | B | Override | Status | |-----|-----|------------|----------| | 0 | 0 | 0 | 0 | | 0 | 0 | 1 | 0 | | 0 | 1 | 0 | 0 | | 0 | 1 | 1 | 0 | | 1 | 0 | 0 | 0 | | 1 | 0 | 1 | 0 | | 1 | 1 | 0 | 1 | | 1 | 1 | 1 | 0 |
Simulation shows Status = X for input A=1, B=1, Override=1. The output resolves to an unknown state instead of the expected logic level. Inspect the circuit and correct the fault.
Constraints
- Do not change the module port list.
- Consolidate the logic to ensure only one driver controls the output.
