|
||
List<Trace> routeDifferentialPair(...);
|
||
List<Trace> addLengthMatching(...); // 等长补偿

||
List<String> checkDifferentialPairRules(...); // DRC 检查
|
||
}
|
||
```

||
|
||
**配置参数**:

```dart
|
||
class BusRouter {
|
||
BusNet createBus(...);
|
||
List<Net> routeBus(...);

**配置参数**:
|
||
| 参数 | 说明 |
|
||
|------|------|

|
||
### 功能 #3: 自动布局 (Auto Placement)
|
||
|
||
**功能描述**:
|
||
基于力导向算法自动摆放元件位置，减少连线交叉，优化布局。
|
||
|
||
**核心类**:
|
||
```dart
|
||
class AutoPlacementEngine {
|
||
Future<PlacementResult> placeComponents(...);
|
||
Future<void> undoPlacement(...); // 撤销布局
|
||
}
|
||
```
|
||
|
||
**算法流程**:
|
||
```
|
||
1. 计算连接关系 (Connectivity Graph)
|
||
2. 力导向布局 (Force-Directed)
|
||
- 吸引力：连接的元件相互吸引 (弹簧模型)
|
||
- 排斥力：所有元件相互排斥 (库仑定律)
|
||
3. 优化线长 (Wire Length Optimization)
|
||
4. 避免重叠 (Overlap Avoidance)
|
||
5. 网格对齐 (Grid Snapping)
|
||
```
|
||
|
||
**配置参数**:
|
||
| 参数 | 默认值 | 说明 |
|
||
|------|--------|------|
|
||
| gridSpacing | 100mm | 网格间距 |
|
||
| margin | 50mm | 边界余量 |
|
||
| optimizeWireLength | true | 优化线长 |
|
||
| avoidOverlap | true | 避免重叠 |
|
||
| maxIterations | 100 | 最大迭代次数 |
|
||
|
||
**使用示例**:
|
||
```dart
|
||
final placementEngine = AutoPlacementEngine();
|
||
|
||
// 执行自动布局
|
||
final result = await placementEngine.placeComponents(
|
||
design: design,
|
||
config: AutoPlacementConfig(
|
||
gridSpacing: 100.0,
|
||
optimizeWireLength: true,
|
||
avoidOverlap: true,
|
||
),
|
||
);
|
||
|
||
// 撤销布局
|
||
await placementEngine.undoPlacement(
|
||
result: result,
|
||
design: design,
|
||
);
|
||
```
|
||
|
||
**性能**:
|
||
| 元件数 | 布局时间 | 迭代次数 |
|
||
|--------|----------|----------|
|
||
| 10 | <50ms | 20 |
|
||
| 50 | <200ms | 50 |
|
||
| 100 | <500ms | 80 |
