||||
```dart
|
||||
class DifferentialPairRouter {
|
||||
DifferentialPairNet createDifferentialPair(...);
|
||||
List<Trace> routeDifferentialPair(...);
|
||||
List<Trace> addLengthMatching(...); // 等长补偿

|
||||
}
|
||||
```
|
||||
|
||||
**配置参数**:

|
||||
class BusRouter {
|
||||
BusNet createBus(...);
|
||||
List<Net> routeBus(...);
|
||||
List<Trace> autoFanout(...); // 自动扇出

|
||||
|
||||
**配置参数**:
|

|
||||
config: BusConfig(
|
||||
name: 'DATA',
|
||||
bitCount: 8,
|
||||
busPattern: 'D[%d]', // D[0], D[1], ... D[7]

|
||||
endPoint: Offset(400, 100),

||||
endComponentId: 'MEMORY',
|
||||
);

||||
|
||||
### 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 |
|
