+# Vivado 联动功能需求文档
+
+## 1. 项目背景
+
+### 1.1 当前状态
+
+IC Coder Plugin 目前支持：
+
+- iverilog 仿真（内置 Windows 版本）
+- VCD 波形查看
+- Verilog 代码生成和文件操作
+
+### 1.2 需求来源
+
+用户需要在 VS Code 中直接调用本地 Vivado 工具，并将产出文件自动导入到项目中，完成从仿真到 FPGA 部署的完整流程。
+
+### 1.3 Vivado 是什么？
+
+**Vivado** 是 Xilinx（现 AMD）的 FPGA 开发工具，用于将 Verilog 代码部署到 FPGA 硬件：
+
+- **综合（Synthesis）**：将 RTL 代码转换为门级网表
+- **实现（Implementation）**：布局布线，映射到具体 FPGA 芯片
+- **生成比特流（Bitstream）**：生成 .bit 配置文件用于烧录
+
+**与 iverilog 的区别**：
+
+- iverilog：只做**仿真验证**（软件层面验证逻辑）
+- Vivado：做**综合+实现+生成配置文件**（真正部署到硬件）
+
+**典型开发流程**：
+
+```
+编写 Verilog → iverilog 仿真验证 → Vivado 综合 → Vivado 实现 → 生成 .bit 文件 → 烧录到 FPGA
+```
+
+## 2. 功能目标
+
+### 2.1 核心目标
+
+- **前端提供原子工具**：前端只提供独立的 Vivado 命令工具，不控制流程
+- **后端AI控制流程**：所有执行顺序、依赖检查由后端AI决策
+- **工具职责单一**：每个工具只负责执行一个具体命令
+- **结果透明返回**：执行结果完整返回给后端，由后端决定下一步
+
+### 2.2 设计原则
+
+- 前端不做流程判断，只执行命令
+- 前端不检查依赖关系，由后端保证顺序
+- 前端返回详细的执行结果，包括成功/失败、输出、报告等
+- 后端AI根据结果智能决策是否继续
+
+## 3. 功能详细需求
+
+### 3.1 前端提供的工具
+
+前端提供 4 个独立的工具，每个工具只负责执行一个命令：
+
+#### 3.1.1 createVivadoProject - 创建工程
+
+- **输入**：项目名称、芯片型号、源文件列表、约束文件（可选）
+- **输出**：工程文件（.xpr）
+- **说明**：创建 Vivado 工程，不执行任何构建操作
+
+#### 3.1.2 runVivadoSynthesis - 综合
+
+- **输入**：工程路径或源文件、芯片型号、顶层模块、约束文件（可选）
+- **输出**：.dcp 文件、综合报告
+- **说明**：执行综合，前端不检查工程是否存在。约束文件在此阶段可选，主要用于时序约束
+
+#### 3.1.3 runVivadoImplementation - 实现
+
+- **输入**：综合后的 .dcp 文件路径、约束文件（必需，包含管脚约束）
+- **输出**：实现后的 .dcp 文件、时序报告
+- **说明**：执行实现，前端不检查 .dcp 是否存在。**管脚约束是必需的**，否则无法完成布局布线
+
+#### 3.1.4 runVivadoBitstream - 生成比特流
+
+- **输入**：实现后的 .dcp 文件路径
+- **输出**：.bit 文件（可下载到 FPGA 的配置文件）
+- **核心依赖**：
+  1. 实现已完成
+  2. 工程指定目标芯片型号
+  3. 已完成管脚约束（无管脚约束无法生成）
+- **说明**：生成比特流，前端不检查 .dcp 是否存在
+
+### 3.2 配置管理
+
+#### 3.2.1 配置项
+
+```json
+{
+  "vivado": {
+    "enabled": true,
+    "executablePath": "C:/Xilinx/Vivado/2023.1/bin/vivado.bat",
+    "workingDir": "${workspaceFolder}/vivado_project",
+    "part": "xc7a35tcpg236-1", // FPGA 型号
+    "commands": {
+      "synthesis": "vivado -mode batch -source synth.tcl",
+      "implementation": "vivado -mode batch -source impl.tcl",
+      "bitstream": "vivado -mode batch -source bitstream.tcl"
+    },
+    "outputFiles": {
+      "synthesis": ["*.dcp", "*_synth.rpt"],
+      "implementation": ["*.dcp", "*_timing.rpt", "*_utilization.rpt"],
+      "bitstream": ["*.bit"]
+    }
+  }
+}
+```
+
+#### 3.2.2 存储位置
+
+- 全局配置：VS Code Settings（`settings.json`）
+- 项目配置：`.vscode/ic-coder-vivado.json`（优先级更高）
+
+### 3.3 工具调用接口
+
+#### 3.3.1 通用响应格式
+
+所有工具返回统一的响应格式：
+
+```typescript
+interface VivadoToolResponse {
+  success: boolean;           // 是否成功
+  command: string;            // 执行的命令
+  executionTime: number;      // 执行时间（毫秒）
+  output: string;             // 完整输出日志
+  error?: string;             // 错误信息（如果失败）
+  outputFiles?: string[];     // 产出文件路径列表
+  reports?: {
+    resources?: string;       // 资源使用摘要
+    timing?: string;          // 时序信息摘要
+  };
+}
+```
+
+#### 3.3.2 各工具的参数定义
+
+**createVivadoProject**
+```typescript
+{
+  projectName: string;        // 项目名称
+  part: string;               // 芯片型号
+  topModule: string;          // 顶层模块
+  files: string[];            // 源文件列表
+  constraints?: string;       // 约束文件（可选）
+  mode: 'gui' | 'batch';      // 执行模式
+}
+```
+
+**runVivadoSynthesis**
+```typescript
+{
+  projectPath?: string;       // 工程路径（可选，如果有工程）
+  part: string;               // 芯片型号
+  topModule: string;          // 顶层模块
+  files?: string[];           // 源文件（如果没有工程）
+  constraints?: string;       // 约束文件（可选）
+  mode: 'gui' | 'batch';      // 执行模式
+}
+```
+
+**runVivadoImplementation**
+```typescript
+{
+  dcpFile: string;            // 综合后的 .dcp 文件路径
+  constraints: string;        // 约束文件（必需，包含管脚约束）
+  mode: 'gui' | 'batch';      // 执行模式
+}
+```
+
+**runVivadoBitstream**
+```typescript
+{
+  dcpFile: string;            // 实现后的 .dcp 文件路径
+  mode: 'gui' | 'batch';      // 执行模式
+}
+```
+
+### 3.4 后端AI的职责
+
+后端AI负责：
+1. 询问用户必要参数（芯片型号、执行模式等）
+2. 理解用户意图，决定调用哪些工具
+3. 按正确顺序调用工具（遵循依赖关系）
+4. 检查每步执行结果，决定是否继续
+5. 汇总结果并展示给用户
+
+#### 3.4.1 询问用户参数
+
+后端必须询问：
+- **芯片型号**（必需）："请提供 FPGA 芯片型号（例如：xc7a35tcpg236-1）"
+- **执行模式**（必需）："选择执行模式：1) 图形化 2) 后端执行"
+- **约束文件**（必需）："请提供约束文件（.xdc），包含管脚约束和时序约束"
+
+#### 3.4.2 理解依赖关系
+
+后端AI需要理解：
+```
+创建工程 → 综合 → 实现 → 生成比特流
+```
+
+如果用户说"做实现"，后端应该：
+1. 先调用 `createVivadoProject` 创建工程
+2. 再调用 `runVivadoSynthesis` 执行综合
+3. 最后调用 `runVivadoImplementation` 执行实现
+
+#### 3.4.3 逐步调用工具
+
+```
+步骤1: 调用 createVivadoProject
+       检查 response.success
+       如果失败 → 停止并报错
+
+步骤2: 调用 runVivadoSynthesis
+       检查 response.success
+       如果失败 → 停止并报错
+
+步骤3: 调用 runVivadoImplementation
+       检查 response.success
+       返回最终结果
+```
+
+### 3.5 UI 交互
+
+#### 3.5.1 配置界面
+
+- 在设置页面添加 "Vivado 配置" 选项
+- 支持配置 Vivado 路径、FPGA 型号
+- 支持测试 Vivado 可用性（点击按钮测试）
+
+#### 3.5.2 调用界面
+
+- 在聊天面板中，AI 可以建议使用 Vivado
+- 用户确认后，显示执行进度对话框
+- 实时显示日志输出（可折叠）
+- 显示执行状态：准备中 → 执行中 → 完成/失败
+
+#### 3.5.3 结果展示
+
+- 执行成功：显示执行时间、资源使用、时序信息
+- 执行失败：显示错误信息、建议解决方案
+- 导入文件：高亮显示已导入的文件，支持点击打开报告
+
+### 3.6 后端集成
+
+#### 3.6.1 工具定义
+
+后端注册 4 个独立工具：
+
+```json
+{
+  "name": "createVivadoProject",
+  "description": "创建 Vivado 工程。需要先询问用户芯片型号和执行模式。",
+  "parameters": {
+    "projectName": "项目名称",

+  }
+}
+```
+
+#### 3.6.2 后端调用示例
+
+**场景：用户要求完整流程**
+
+```
+用户: 用 Vivado 跑完整流程
+
+AI: 请提供芯片型号和执行模式
+用户: xc7a35tcpg236-1，后端执行
+
+AI 执行:
+1. [调用] createVivadoProject({ projectName: "counter", part: "xc7a35tcpg236-1", ... })

+
+4. [调用] runVivadoBitstream({ dcpFile: "counter_impl.dcp", ... })
+   [结果] { success: true, outputFiles: ["counter.bit"] }
+
+AI 回复: 完成！已生成 counter.bit 文件
+```
+
+## 4. 用户场景
+
+### 4.1 场景一：完整流程执行
+
+**用户输入**："用 Vivado 跑完整个 FPGA 流程"
+
+**AI 交互**：
+```
+AI: 好的，我将使用 Vivado 执行完整的 FPGA 开发流程。请提供以下信息：
+
+1. FPGA 芯片型号（例如：xc7a35tcpg236-1）
+2. 请选择要执行的步骤（可多选）：
+   - 综合（Synthesis）
+   - 实现（Implementation）
+   - 生成比特流（Bitstream）
+3. 执行模式：
+   - 图形化模式：打开 Vivado GUI
+   - 后端执行：自动在后台执行
+4. 约束文件路径（.xdc，必需）
+
+用户: xc7a35tcpg236-1，全部步骤，后端执行，约束文件是 counter.xdc
+
+AI: 收到！执行计划：
+1. 创建工程
+2. 综合
+3. 实现
+4. 生成比特流
+
+开始执行...
+
+[步骤 1/4] 创建工程...
+✓ 工程创建成功（耗时 2s）
+
+[步骤 2/4] 综合中...
+✓ 综合完成（耗时 45s）
+  资源使用：LUT 32/20800 (0.15%), FF 8/41600 (0.02%)
+
+[步骤 3/4] 实现中...
+✓ 实现完成（耗时 120s）
+  时序：WNS 5.234ns, TNS 0.000ns（满足要求）
+
+[步骤 4/4] 生成比特流...
+✓ 比特流生成完成（耗时 15s）
+
+所有步骤执行完毕！产出文件已导入到 vivado_output/ 目录。
+```
+
+### 4.2 场景二：只执行实现（自动补充依赖）
+
+**用户输入**："用 Vivado 做实现"
+
+**AI 交互**：
+```
+AI: 请提供以下信息：
+1. FPGA 芯片型号
+2. 执行模式（图形化/后端执行）
+
+用户: xc7a35tcpg236-1，后端执行
+
+AI: 注意：实现依赖综合，我将自动执行以下步骤：
+1. 创建工程
+2. 综合（前置依赖）
+3. 实现（您选择的步骤）
+
+是否继续？
+
+用户: 是
+
+AI: 开始执行...
+[自动执行创建工程 → 综合 → 实现]
+```
+
+### 4.3 场景三：图形化模式
+
+**用户输入**："打开 Vivado 图形界面做综合"
+
+**AI 交互**：
+```
+AI: 请提供芯片型号：
+用户: xc7a35tcpg236-1
+
+AI: 正在创建工程并打开 Vivado GUI...
+✓ 工程已创建
+✓ Vivado 图形界面已启动
+
+您现在可以在 Vivado 中手动操作。完成后，产出文件将保存在工程目录中。
+```
+
+### 4.4 场景四：执行中断处理
+
+**执行过程**：
+```
+[步骤 1/3] 创建工程...
+✓ 成功
+
+[步骤 2/3] 综合中...
+✗ 综合失败
+错误：ERROR: [Synth 8-439] module 'counter' not found
+
+AI: 综合失败，发现以下问题：
+- 找不到模块 'counter'
+
+建议检查：
+1. 模块名是否正确
+2. 文件中是否定义了该模块
+3. 是否有语法错误
+
+执行已停止，请修复错误后重试。
+```
+
+## 5. 技术约束
+
+### 5.1 平台兼容性
+
+- Windows：支持 `.bat` 可执行文件
+- Linux：支持 shell 脚本
+- 路径分隔符自动适配
+
+### 5.2 性能要求
+
+- 命令执行不阻塞 UI
+- 综合时间可能较长（分钟级），需要进度提示
+- 日志输出实时更新，限制缓冲区大小
+
+### 5.3 安全性
+
+- 工作目录限制在项目范围内
+- 许可证路径不记录到日志
+
+## 6. 验收标准
+

+
+## 2. 前端职责
+
+- 接收后端工具调用
+- 生成对应的 TCL 脚本
+- 执行 Vivado 命令
+- 捕获输出日志
+- 解析报告文件（提取资源和时序摘要）
+- 返回执行结果
+
+**前端不做**：
+- 不检查依赖关系
+- 不验证执行顺序
+- 不控制流程
+
+## 3. 后端职责
+
+- 询问用户参数（芯片型号、执行模式等）
+- 理解依赖关系（创建工程 → 综合 → 实现 → 生成比特流）
+- 按正确顺序调用工具
+- 检查每步的 `success` 字段
+- 如果失败，读取 `error` 字段并提示用户
+- 汇总结果展示给用户
+
+## 4. 调用示例
+
+```
+用户: 用 Vivado 做综合
+
+后端:
+1. 询问芯片型号 → xc7a35tcpg236-1
+2. 询问执行模式 → batch
+
+3. 调用 createVivadoProject(...)
+   返回: { success: true, outputFiles: ["counter.xpr"] }
+
+4. 调用 runVivadoSynthesis(...)
+   返回: { success: true, outputFiles: ["counter_synth.dcp"], reports: {...} }
+
+5. 展示结果给用户
+```
+
+## 5. 错误处理
+
+如果某步失败：
+```typescript
+{
+  success: false,
+  error: "ERROR: [Synth 8-439] module 'counter' not found",
+  output: "详细日志..."
+}
+```
+
+后端应该：
+1. 停止后续步骤
+2. 提取 `error` 字段
+3. 给用户提示和建议

+
+```
+后端 AI
+  ↓ 调用工具
+前端 Extension (messageHandler.ts)
+  ↓ 调用
+VivadoRunner (utils/vivadoRunner.ts)
+  ↓ 生成 TCL 脚本并执行
+本地 Vivado
+```
+
+## 2. 核心模块
+
+### 2.1 VivadoRunner
+
+**职责**：执行单个 Vivado 命令
+
+**主要方法**：
+- `createProject()` - 创建工程
+- `runSynthesis()` - 执行综合
+- `runImplementation()` - 执行实现
+- `runBitstream()` - 生成比特流
+
+**实现要点**：
+- 根据参数生成 TCL 脚本
+- 启动子进程执行 Vivado
+- 捕获输出日志
+- 解析报告文件
+- 返回结果
+
+### 2.2 TCL 脚本生成
+
+**创建工程**：
+```tcl
+create_project {projectName} {workDir} -part {part} -force
+add_files -norecurse {files}
+set_property top {topModule} [current_fileset]
+```
+
+**综合**：
+```tcl
+synth_design -part {part} -top {topModule}
+report_utilization -file utilization.rpt
+write_checkpoint -force synth.dcp
+```
+
+**实现**：
+```tcl
+open_checkpoint {dcpFile}
+opt_design
+place_design
+route_design
+report_timing_summary -file timing.rpt
+write_checkpoint -force impl.dcp
+```
+
+**生成比特流**：
+```tcl
+open_checkpoint {dcpFile}
+write_bitstream -force output.bit
+```
+
+### 2.3 MessageHandler 集成
+
+```typescript
+// 处理工具调用
+async function handleToolCall(toolName: string, params: any) {
+  switch(toolName) {
+    case 'createVivadoProject':
+      return await vivadoRunner.createProject(params);
+    case 'runVivadoSynthesis':
+      return await vivadoRunner.runSynthesis(params);
+    case 'runVivadoImplementation':
+      return await vivadoRunner.runImplementation(params);
+    case 'runVivadoBitstream':
+      return await vivadoRunner.runBitstream(params);
+  }
+}
+```
+
+## 3. 配置管理
+
+**配置文件位置**：
+- 全局：`settings.json` 中的 `ic-coder.vivado`
+- 项目：`.vscode/ic-coder-vivado.json`
+
+**配置项**：
+```json
+{
+  "vivado": {
+    "enabled": true,
+    "executablePath": "C:/Xilinx/Vivado/2023.1/bin/vivado.bat",
+    "workingDir": "${workspaceFolder}/vivado_project"
+  }
+}
+```
+
+## 4. 文件结构
+
+```
+src/
+├── utils/
+│   ├── vivadoRunner.ts       # Vivado 执行器
+│   ├── vivadoConfig.ts       # 配置读取
+│   └── tclGenerator.ts       # TCL 脚本生成
+└── utils/
+    └── messageHandler.ts     # 工具调用处理（新增部分）
+```
+
+## 5. 实现要点
+
+### 5.1 子进程执行
+
+```typescript
+const process = spawn(vivadoPath, ['-mode', 'batch', '-source', tclPath]);
+
+process.stdout.on('data', (data) => {
+  output += data.toString();
+});
+
+process.on('close', (code) => {
+  resolve({ success: code === 0, output });
+});
+```
+
+### 5.2 报告解析
+
+从 `.rpt` 文件中提取关键信息：
+- 资源使用：LUT、FF、BRAM 数量
+- 时序信息：WNS、TNS
+
+### 5.3 错误处理
+
+捕获常见错误：
+- Vivado 未配置
+- 文件不存在
+- 综合/实现失败
+- 时序不满足
+
+返回清晰的错误信息给后端。
+
+## 6. 测试
+
+**单元测试**：
+- TCL 脚本生成正确性
+- 配置读取
+
+**集成测试**：
+- 完整流程测试（需要本地 Vivado）
+- 错误处理测试
