chip-spyglass-rdc-resolver

chip-spyglass-rdc-resolver is a skill for Claude Code from zhaixin244-wq/fnw. It costs 75 tokens per session (1,971 once invoked), scanned A, original, MIT.

An RTL review helper for SpyGlass RDC reports. It reads reset-domain crossing violations, ranks them, and suggests RTL fixes or creates waiver files for accepted findings.

In plain words
What is it for?
Use it to process rdc_summary.log and related SpyGlass reports before RDC sign-off, review violations in RTL, and generate fix recommendations or waivers.
Why use it?
It reduces the manual work of finding the root cause of RDC violations and deciding which findings need a fix or an exception.

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-spyglass-rdc-resolver 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 9d 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.

Chip SpyGlass RDC Resolver

分析 SpyGlass RDC 报告,通过 LLM 与知识库中的 RDC 规则信息,对 RTL 进行分析,给出修改建议或生成 waiver 文件。

When to Use

  • 处理 chip-spyglass-rdc-chk 生成的 RDC 报告(rdc_summary.logrdc_verify.log
  • 需要分析 RDC 违例的根因并给出 RTL 修改建议
  • 需要为可接受的违例生成 waiver 文件
  • RDC 签核前的违例清理

核心工作流

0. 加载 Blackbox 模块列表
1. 解析 RDC 报告 → 提取 (rule, severity, file, line, message) 元组
2. 过滤 Blackbox → 模块在 blackbox 列表中的违例自动 waive
3. 按优先级分类违例 → P0~P4
4. 对 P0/P2 违例:必须修复,LLM 分析 RTL 给出修改方案
5. 对 P1/P3/P4 违例:LLM 分析判断是否真问题,修复或 waive
6. 输出:RTL 修改建议 + waiver 文件

Step 0: 加载 Blackbox 模块列表

读取 blackbox-modules.md(本 SKILL.md 同目录),加载 blackbox 模块列表。

判定规则:

  • 模块名匹配 blackbox 列表条目,或
  • 违例文件路径包含 blackbox 模块名

如果 blackbox-modules.md 为空或不存在,跳过此步骤。

Step 1: 解析 RDC 报告

RDC 报告来自 chip-spyglass-rdc-chk 的输出,典型路径:

  • {module}_work/ds/report/rdc/rdc_summary.log — 汇总报告
  • {module}_work/ds/report/rdc/3_rdc_verify.log — 亚稳态检查
  • {module}_work/ds/report/rdc/4_rdc_verify_corrupt.log — 数据损坏检查

SpyGlass 日志格式:

Warning [<rule_name>] <file>:<line> <message>
Error [<rule_name>] <file>:<line> <message>

提取:rule_name、severity、file path、line number、violation message。

Step 2: 过滤 Blackbox 违例

对每个解析出的违例,检查其模块是否在 blackbox 列表中。Blackbox waive 的违例在 waiver 文件中单独一节输出。

Step 3: 按优先级分类违例

rdc-rules-reference.md(本 SKILL.md 同目录)中的规则映射表。

如果规则不在映射表中,标记为 "unknown rule" 并提示用户手动分类。

Step 4: 执行优先级动作

优先级 动作 输出
P0 (Async Reset Metastability) 必须修复。 添加复位同步器或设置 reset ordering RTL 修改建议
P1 (Reset-less Path Corruption) 分析判断。 添加 qualifier 或 safe-stating 逻辑 修复或 waive
P2 (RDC on Clock Path) 必须修复。 复位信号禁止组合逻辑驱动时钟 RTL 修改建议
P3 (Reset Convergence) 分析判断。 检查复位是否正确分组 修复或 waive
P4 (Power Domain RDC) 分析判断。 需 UPF 确认隔离/开关 修复或 waive

关键规则:P0 和 P2 绝对禁止 waive,必须从设计层面修复。

Step 5: 生成输出

5a. RTL 修改建议 (rdc_fix_proposal.md)
# RDC Fix Proposal

## Summary
- Total violations: N
- Blackbox waived: N
- P0 must-fix: N (Async Reset Metastability)
- P2 must-fix: N (RDC on Clock Path)
- P1/P3/P4 reviewed: N
  - Fix required: N
  - Waived: N
- Unknown rules: N

## P0 — Must Fix (NEVER Waive)

What ships with it

What this file has done since we first saw it

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.
