值得了解

  • EDA工具之于芯片，如同编译器之于软件——没有它们，现代芯片无法设计

  • Cadence的仿真平台Palladium运行一台需要数百台服务器集群的算力

  • 一颗先进SoC芯片的设计数据量可达数TB，需要数月计算完成布局布线

  • 全球几乎所有智能手机和PC的芯片都经过了Cadence工具的设计或验证

  • Cadence创始人Jim Solomon曾是GE的工程师，创立前公司在PCB设计领域已有积累

  • 公司每年处理的芯片设计项目超过50,000个

  • EDA行业的竞争格局自2010年以来几乎没有变化，三巨头地位稳固

  • Cadence在AI芯片设计自动化方面投资超过10年，近期才开始大规模商用

Usage Guidance
This skill is an instruction-only company profile: it does not request any credentials, make installs, or instruct system access, so it's internally coherent and low-risk. However, the source/homepage are unspecified and the owner ID is unknown—treat the content as informational and verify any factual or financial claims (e.g., revenue, market share, product support for specific process nodes) against official filings, Cadence press releases, or reputable industry analysis before using it for investment or technical decisions. If you later see this skill modified to include network calls, downloads, or environment variables, reassess immediately.
Capability Analysis
Type: OpenClaw Skill Name: cadence Version: 1.0.0 The skill bundle consists entirely of informational content regarding Cadence Design Systems (an EDA company). It contains no executable code, scripts, or instructions that could lead to data exfiltration, remote execution, or prompt injection. All files, including SKILL.md and _meta.json, are aligned with the stated purpose of providing corporate and industry analysis.
Capability Assessment
✓ Purpose & Capability
Name/description (Cadence company profile) align with the SKILL.md content. The skill asks for nothing (no env, binaries, or paths) and only contains informational instructions appropriate for a company/industry briefing.
✓ Instruction Scope
SKILL.md is an informational document (history, business analysis, metrics) and the 'read_when' triggers are limited to queries about the company, market, or investment analysis. It does not instruct the agent to read local files, access environment variables, make external uploads to unknown endpoints, or perform unrelated system actions.
✓ Install Mechanism
No install specification and no code files are present; nothing will be written to disk or installed. This is the lowest-risk pattern for a skill of this type.
✓ Credentials
Requires no environment variables, credentials, or config paths. There is no disproportionate secret or credential access for the stated purpose.
✓ Persistence & Privilege
Flags show default behavior (not always-enabled, agent invocation allowed). There is no request to persist settings, modify other skills, or gain elevated privileges.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install cadence
  3. After installation, invoke the skill by name or use /cadence
  4. Provide required inputs per the skill's parameter spec and get structured output
