chip-budget-allocator

chip-budget-allocator is a skill for Claude Code from zhaixin244-wq/fnw. It costs 73 tokens per session (871 once invoked), scanned A, original, MIT.

A planner for distributing system-level PPA targets across chip submodules. PPA means performance, power, and area; the planner also checks whether the submodule budgets add up to the system target.

In plain words
What is it for?
Use it to allocate latency, throughput, power, area, and frequency targets to submodules, then review the totals and identify budget risks.
Why use it?
It replaces ad hoc budget splitting with a visible allocation and highlights modules that exceed their limits or lack enough margin.

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-budget-allocator 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.

What it actually says

Chip Budget Allocator

任务

将系统级 PPA 指标自顶向下拆解到子模块,并确保预算闭合。

执行步骤

  1. 收集系统级目标:
    • Latency Budget、Throughput Budget、Power Budget、Area Budget、Frequency Target。
  2. 分析模块层次结构,识别关键子模块及其交互关系。
  3. 基于经验公式和快速模型,将系统指标分配到各子模块:
    • Latency:按流水线级数或路径延迟比例分配。
    • Throughput:按数据宽度和处理速率分配。
    • Power:按活动因子、翻转率、SRAM 容量分配。
    • Area:按逻辑门数、SRAM、布线通道估算分配。
  4. 计算预算总和,检查是否与系统目标闭合(含 10-20% 裕量)。
  5. 对超出预算或裕量不足的模块标注风险并建议优化方向。

输出格式

### PPA 预算分配表

#### Latency Budget (@ 1GHz)
| 子模块 | 预算 (cycles) | 占比 | 裕量 | 备注 |
|--------|---------------|------|------|------|

#### Power Budget (mW)
| 子模块 | 动态功耗 | 漏电流 | 占比 | 裕量 |
|--------|----------|--------|------|------|

#### Area Budget (kGates + mm²)
| 子模块 | 逻辑门 | SRAM | 总面积 | 占比 |
|--------|--------|------|--------|------|

**闭合检查:X/Y = Z% (建议 ≥ 85% 且 ≤ 100%)**

使用示例

示例 1:系统级 PPA 拆解

用户:帮我把 data_adpt 的 PPA 目标拆到子模块,目标延迟 10 cycles @ 1GHz,面积 150kGates,功耗 15mW

预期行为:

  1. 列出 data_adpt 的子模块(buf、crc、align 等)
  2. 按流水线级数分配延迟,按逻辑复杂度分配面积,按活动因子分配功耗
  3. 输出闭合检查,超预算项标红

示例 2:检查预算闭合

用户:检查 data_adpt 各子模块的 PPA 预算是否闭合

预期行为:汇总各子模块预算,与系统目标对比,输出闭合率

异常处理

场景 触发条件 处理动作
系统目标缺失 用户未提供 PPA 目标 暂停,列出需要的指标清单,等待用户补充
子模块未确定 模块层次不清晰 先输出建议的子模块划分,用户确认后再分配
预算不闭合 总和 > 系统目标 标红超预算项,建议优化方向(降频/减并行/缩缓存)
估算无依据 经验公式不适用 标注"待综合验证",建议用 DSE Skill 进一步探索

检查点

  • 分配前:展示系统级目标和子模块列表,用户确认后开始分配
  • 分配后:展示闭合检查结果,超预算项需用户确认是否接受

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-budget-allocator is a skill published in the GitHub repository zhaixin244-wq/fnw (29 stars, last pushed 3mo ago), licensed MIT. It adds 73 tokens to every session and 871 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.
