chip-impl-parallel-dev

chip-impl-parallel-dev is a skill for Claude Code from zhaixin244-wq/fnw. It costs 68 tokens per session (1,578 once invoked), scanned A, original, MIT.

A workflow for developing multiple RTL hardware modules in parallel. RTL is code that describes how digital circuits operate, and a submodule is one part of a larger chip design.

In plain words
What is it for?
Planning, assigning, linting, synthesizing, integrating, and reviewing multi-module RTL projects.
Why use it?
It organizes dependencies, separate work folders, checks, and final integration so independent hardware modules can be developed at the same time.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

chip-impl-parallel-dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

并行开发 Skill

任务

多模块并行开发流程:分析→调度→集成→确认。

流程

Phase 1: Plan Mode 分析

  1. Glob 搜索 {module}_work/ds/rtl/*.v 获取子模块 RTL 文件列表。若文件不存在,暂停并提示用户
  2. 确认输入:PR/FS/UA 文档
  3. RAG 检索 CBB 依赖
  4. 划分模块,评估依赖关系
  5. 确定并行组(无依赖模块可并行)

输出格式

### 模块开发清单
| 模块名 | 依赖 | 复杂度 | 预估工时 | 并行组 |
|--------|------|--------|----------|--------|
| buf_mgr | sync_fifo | 中 | 2h | Group-A |
| ctrl_fsm | 无 | 高 | 3h | Group-A |
| top_int | buf_mgr, ctrl_fsm | 低 | 1h | Group-B |

Phase 2: 并行 Subagent 开发

为每个可并行模块启动独立 subagent:

Agent({
  description: "RTL 开发 - {模块名}",
  subagent_type: "chip-code-writer",
  prompt: "开发 {module_name} 模块 RTL..."
})

调度规则

规则 说明
依赖优先 有依赖的模块必须等待依赖完成
无依赖并行 无依赖模块可同时启动
独立工作目录 每个模块使用独立 {module}_work/
独立检查 每个模块独立执行 Lint + 综合

Phase 3: 顶层集成

所有子模块完成后:

  1. 顶层 Lint 检查(ALL PASS)
  2. 顶层综合检查(ALL PASS + 面积达标)
  3. 检查模块间接口一致性

Phase 4: PR/FS/UA 确认

确认维度 检查方法
功能覆盖 对照 FS §4 功能列表
接口一致 对照 FS §6 接口定义
PPA 达标 对照 FS §8 PPA 规格
需求追溯 对照 RTM(FS §14)

冲突检测

监控路径

文件类型 路径模式 冲突级别
顶层 RTL {module}_work/rtl/{top_module}.v Critical
CBB 清单 {module}_work/ds/doc/*_cbb_list.md Major
SDC 约束 {module}_work/syn/{top_module}.sdc Major
子模块 RTL {module}_work/rtl/{submodule}.v Info(独立目录不冲突)

文件锁机制(跨平台)

Linux/macOS — flock 原子锁

lock_file="{module}_work/.lock.{file_type}"
exec 200>"$lock_file"
if ! flock -n 200; then
  echo "[CONFLICT] $lock_file held by $(cat $lock_file)"
  exit 1
fi
echo "{agent_id}:$(date +%s)" >&200
# ... 执行 ...
exec 200>&-  # 释放

Windows — PowerShell Mutex

$mutex = New-Object System.Threading.Mutex($false, "Global\{module}_{file_type}")
if (-not $mutex.WaitOne(0)) {
  Write-Error "[CONFLICT] Mutex held by another process"
  exit 1
}
# ... 执行 ...
$mutex.ReleaseMutex()
$mutex.Dispose()

平台检测逻辑

if command -v flock >/dev/null 2>&1; then
  # Linux/macOS: 使用 flock
  ...
elif command -v powershell >/dev/null 2>&1; then
  # Windows: 调用 PowerShell mutex
  powershell -File lock.ps1 ...
else
  # fallback: 文件存在性检查(有竞态风险,仅用于开发环境)
  ...
fi

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

chip-impl-parallel-dev is a skill published in the GitHub repository zhaixin244-wq/fnw (28 stars, last pushed 3mo ago), licensed MIT. It adds 68 tokens to every session and 1,578 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
