Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00078 | $0.01148 |
| Opus 5 | $0.00039 | $0.00574 |
| Sonnet 5 | $0.00016 | $0.00230 |
| Haiku 4.5 | $0.00008 | $0.00115 |
Grade A, and why
chip-impl-sdc-sva 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 11d 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.

SDC/SVA/TB 编写 Skill
任务
基于微架构时钟策略和验证要点生成 SDC 约束、SVA 断言、TB testbench。
输入
rtl_files: RTL 文件列表microarch_doc: 微架构文档port_list: 端口列表
执行步骤
- 用
Glob搜索{module}_work/ds/doc/ua/*.md获取微架构文档列表。若文件不存在,暂停并提示用户
SDC 约束
- 从微架构 §6 提取时钟定义(频率/来源)
- 生成
create_clock/set_input_delay/set_output_delay - 设置
set_false_path(复位信号) - 保存到
{module}_work/run/{module}.sdc
SVA 断言
- 从微架构 §10 提取验证场景
- 实现握手稳定性:
valid && !ready |=> valid - 实现数据稳定性:
valid && !ready |=> $stable(data) - 实现非法状态检测
- 所有 SVA 放在
`ifdef ASSERT_ON内 - 保存到
{module}_work/ds/rtl/{submodule}_sva.sv
TB testbench
- 生成基本 testbench 框架
- 时钟/复位生成
- 实例化 DUT
- 保存到
{module}_work/ds/rtl/{submodule}_tb.v
Run 脚本
- 生成文件列表
{module}_work/run/{module}.f - 生成 Lint 脚本
{module}_work/run/lint.sh - 生成综合脚本
{module}_work/run/synth_yosys.tcl
输出
sdc_file:{module}_work/run/{module}.sdcsva_file:{module}_work/ds/rtl/{submodule}_sva.svtb_file:{module}_work/ds/rtl/{submodule}_tb.vfilelist:{module}_work/run/{module}.flint_script:{module}_work/run/lint.shsynth_script:{module}_work/run/synth_yosys.tcl
Gate
无强制门禁,但 SDC 时钟周期必须与微架构 §6 一致。
Metrics
执行完成后记录到 {work_dir}/ds/report/metrics/sdc_sva.json:
{"stage_id": "sdc_sva", "duration_ms": 0, "iteration_count": 1}
使用示例
示例 1:
- 用户:「为 data_adpt 生成 SDC 约束和 SVA 断言」
- 行为:从微架构 §6 提取时钟定义生成
create_clock/set_input_delay/set_output_delay,从 §10 提取验证场景生成握手/数据稳定性断言,保存到对应目录
示例 2:
- 用户:「帮我写 buf_mgr 的 testbench 框架」
- 行为:生成基本 TB 框架(时钟/复位生成 + DUT 实例化 + 文件列表),保存到
buf_mgr_work/ds/rtl/buf_mgr_tb.v,同步生成run/lint.sh和run/synth_yosys.tcl
异常处理
| 场景 | 触发条件 | 处理动作 |
|---|---|---|
| 微架构时钟定义缺失 | §6 无时钟频率/来源 | 暂停,提示用户补充时钟策略 |
| 验证场景缺失 | §10 无验证要点 | 仅生成基础握手断言,标注 [SVA-PARTIAL] |
| SDC 时钟周期不一致 | 生成的 SDC 与微架构 §6 矛盾 | 以微架构为准,修正 SDC |
| RTL 文件未就绪 | rtl_files 列表为空 |
暂停,提示先完成 RTL 实现 |
检查点
检查前:
- 确认 RTL 文件列表非空
- 确认微架构文档包含 §6(时钟复位)和 §10(验证要点)
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.
- 11d ago First seen · 92 lines · 78 tokens per session scan A 6f5adc0e6e57
chip-impl-sdc-sva is a skill published in the GitHub repository zhaixin244-wq/fnw (29 stars, last pushed 3mo ago), licensed MIT. It adds 78 tokens to every session and 1,148 once invoked, about $0.0004 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.
