Show HN: 为什么系统建模应该像代码，而不是PPT
1 分•作者: twopowerX•8 个月前
系统工程师使用各种工具对价值数十亿美元的航天器、救生医疗设备和自动驾驶汽车进行建模，但这些工具甚至无法进行像样的 diff/merge/版本控制，即使配备了昂贵的基础设施。
我构建了 Sylang 来解决这个问题。
什么是 Sylang？
一种基于文本的语言，用于对复杂系统进行建模。编写声明式代码，自动获得可视化图表、可追溯性矩阵、FMEA 分析和合规性报告。与 Git、VSCode 和 AI 代码助手配合使用。
示例：
```
def requirement BrakeActivation
description "系统应在 100 毫秒内激活制动器"
safetylevel ASIL-D
testedby ref testcase EmergencyBrakeTest
derivedfrom ref safetygoal PreventCollision
allocatedto ref block BrakeController
```
这会生成：
- 架构图（分解图、内部模块图）
- 可追溯性矩阵（需求 ↔ 测试 ↔ 模块 ↔ 安全目标）
- 覆盖率分析（哪些需求缺少测试？）
- 合规性报告（功能安全、ASPICE 等）
为什么基于文本的建模有效：
您的 AI 代码助手（Cursor、GitHub Copilot、Claude、Gemini）可以：
- 从安全目标生成需求
- 从需求创建测试用例
- 从架构草拟 FMEA 分析
- 通过语义理解在文件之间进行重构
- 建议缺失的关系
真正有效的 Git 工作流程：
```
git diff requirements.req # 查看更改内容
git merge feature/new-sensors # 合并架构分支
git blame safety-goals.sgl # 谁定义了这个安全目标？
```
没有 XMI。没有数据库导出。没有 PowerPoint。只有可读的文本，可以生成您所需的一切。
您将获得：
23 种文件类型，涵盖完整的工程生命周期：
- 产品线和变体 (.ple, .fml, .vml)
- 架构 (.blk, .fun, .ifc)
- 需求和测试 (.req, .tst)
- 行为模型 (.ucd, .seq, .smd)
- 安全分析 (.haz, .sgl, .sam, .flr, .fta)
- 仪表板和规范 (.dash, .spec)
- 自动化 (.agt, .spr)
所有文件都会自动生成可视化图表：特征模型、分解图、序列图、状态机、可追溯性矩阵。
当前状态：
- 语言稳定 (v0.9.27)
- VSCode 扩展可用（在扩展中搜索“Sylang”）
- 与 Cursor、GitHub Copilot、Claude、Gemini 代码助手配合使用
- 图表渲染、可追溯性、覆盖率分析工作正常
- 独立开发者，兼职，公开构建

Systems engineers model billion-dollar spacecraft, life-saving medical devices, and autonomous vehicles in tools that can't even do a proper diff/merge/version control even with large expensive infrastructure.<p>I built Sylang to address that.<p>What is Sylang?<p>A text-based language for modeling complex systems. Write declarative code, get visual diagrams, traceability matrices, FMEA analyses, and compliance reports automatically. Works with Git, VSCode, and AI code assistants.<p>Example:<p><pre><code> def requirement BrakeActivation
description "System shall activate brakes within 100ms"
safetylevel ASIL-D
testedby ref testcase EmergencyBrakeTest
derivedfrom ref safetygoal PreventCollision
allocatedto ref block BrakeController
</code></pre>
This generates:<p>- Architecture diagrams (decomposition, internal block diagrams)
- Traceability matrix (requirement ↔ test ↔ block ↔ safety goal)
- Coverage analysis (which requirements lack tests?)
- Compliance reports (functional safety, ASPICE, etc.)<p>Why text-based modeling works:<p>Your AI code assistant (Cursor, GitHub Copilot, Claude, Gemini) can:
- Generate requirements from safety goals
- Create test cases from requirements
- Draft FMEA analyses from architecture
- Refactor across files with semantic understanding
- Suggest missing relationships<p>Git workflows that actually work:<p><pre><code> git diff requirements.req # See what changed
git merge feature/new-sensors # Merge architecture branches
git blame safety-goals.sgl # Who defined this safety goal?
</code></pre>
No XMI. No database exports. No PowerPoint. Just readable text that generates everything you need.<p>What you get:<p>23 file types covering the full engineering lifecycle:
- Product lines & variants (.ple, .fml, .vml)
- Architecture (.blk, .fun, .ifc)
- Requirements & tests (.req, .tst)
- Behavioral models (.ucd, .seq, .smd)
- Safety analysis (.haz, .sgl, .sam, .flr, .fta)
- Dashboards & specs (.dash, .spec)
- Automation (.agt, .spr)<p>All auto-generating visual diagrams: feature models, decomposition diagrams, sequence diagrams, state machines, traceability matrices.<p>Current state:<p>- Language stable (v0.9.27)
- VSCode extension available (search "Sylang" in Extensions)
- Works with Cursor, GitHub Copilot, Claude, Gemini code assistants
- Diagram rendering, traceability, coverage analysis working
- Solo dev, part-time, building in public<p>Download at:<p><a href="https://marketplace.visualstudio.com/items?itemName=balaji-embedcentrum.sylang" rel="nofollow">https://marketplace.visualstudio.com/items?itemName=balaji-e...</a><p>Website: <a href="https://sylang.dev" rel="nofollow">https://sylang.dev</a><p>GitHub: <a href="https://github.com/balaji-embedcentrum/sylang" rel="nofollow">https://github.com/balaji-embedcentrum/sylang</a><p>Feedback welcome—especially from engineers who've wished their modeling tools worked more like their code editors.
