**result**: warning

**message**: Yosys ABC 无法判断等价性（可能是假阴性）

**details**:
```
======== ABC command line "cec /home/openclawer/Projects/Partition/workspace/merge_1ed885e2/traffic.blif /home/openclawer/Projects/Partition/workspace/merge_1ed885e2/merged.blif"
Line 10: Cannot find the model for subcircuit $reduce_or.
Reading network from file has failed.

```

**说明**: Yosys ABC CEC 无法完成等价性检查。这可能是由于：
1. BLIF 格式中包含 ABC 不支持的算子（如 $reduce_*、$mux 等）
2. Yosys 综合过程中的内部优化导致格式不兼容
3. 工具本身的限制

**后续行动**: 请使用 Icarus Verilog (iverilog) 编写 testbench 进行仿真验证。例如：
```bash
iverilog -o tb.vvp -s tb original.v merged.v
vvp tb.vvp
```

**method**: Yosys BLIF + ABC CEC
**original**: /home/openclawer/Projects/Partition/workspace/merge_1ed885e2/traffic.v
**merged**: /home/openclawer/Projects/Partition/workspace/merge_1ed885e2/merged.v
